Break-in a new shampoo brush
Before using a new shampoo brush on carpet or rugs, breaking-in the brush is required to prevent possible damage to the carpet itself.
Here is the correct way to do it; Mount the new shampoo brush onto your floor machine. Run the brush on rough, unfinished concrete. Run DRY for about 15 minutes, making sure that the brush fill takes on a slight set or lean.
Breaking-in the brush will remove burrs and reduce drag. Rinse off the shampoo brush to remove burrs and soil. If your shampoo brush has a center glide, remove it before breaking-in to prevent damage to the glide.
Your shampoo brush is now ready for use on carpet and rugs.
Cleaning and Disinfectant Applications
Follow the Centers for Disease Control and Prevention (CDC) www.cdc.gov for protocols on: how to clean and disinfect. And follow label directions on your EPA registered disinfectants.
Wear Appropriate personal protective equipment (PPE). Read and follow EPA label directions.
Clean Frequently touched surfaces. Wear disposable gloves to clean and disinfect. High touch surfaces include: Tables, doorknobs, light switches, hand railing, drawer pulls, countertops, handles, desks, phones, keyboards, toilets, faucets, sinks, faucet handles, soap pumps, buttons, etc. wash hands immediately after removing gloves.
Disinfect using EPA registered disinfectant. Follow label instructions.
- Keep surface wet for the appropriate period of time as per label direction.
- Provide ventilation during application of disinfectant.
- Wear PPE as per label directions.
- COVID-19: Make sure to use a disinfectant that meets EPA criteria for use against SARS-CoV-2, the virus that causes COVID-19. These disinfectants will appear on the EPA list N (www.cdc.gov). For example we recommend a chlorine dioxide based EPA registered virucide, BioVex/Oxine, EPA reg no.9804-1. Or use other EPA list N disinfectant.
- Fogging: Fog only disinfectants that label directions state that they may be applied by fogging, wear appropriate PPE for fogging. Evacuate everybody not wearing appropriate PPE. Fully ventilate before allowing access to the area again.
- Never make a kill claim. Do not claim sterilization, disinfection or even sanitation. Claim only, application of (name of product) as per label directions.
- For long term microbiostatic protection, apply MonoFoil D EPA registered disinfectant (EPA no. 90856-4-92366) for up to one week of 24/7 microbiostatic protection. Or apply MonoFoil M EPA registered bacteriostatic, fungistatic and algistatic finish (EPA no. 90856-2-92366) for up to 3 months of 24/7 microbiostatic protection.
Soft surfaces such as carpet, rugs and upholstery. Clean with solution appropriate for the textile. Use the warmest temperature appropriate for each item. Dry completely. Heat dry if possible. For long term microbiostatic protection apply MonoFoil D, EPA registered disinfectant (EPA no. 90856-4-92366) for up to one week of 24/7 microbiostatic protection. Or apply MonoFoil M, EPA registered bacteriostatic, fungistatic and algistatic finish (EPA no. 90856-2-92366) for up to 3 months of 24/7 microbiostatic protection.
Laundry items should be washed according to the manufactures instructions, use the warmest temperature appropriate for each item. Dry completely. Heat dry if possible. Do not shake laundry. Do not make contamination air-borne. Clean and disinfect clothes hampers. Wash hands as soon as you remove your disposable gloves. For long term microbiostatic protection apply MonoFoil D, EPA registered disinfectant (EPA no. 90856-4-92366) for up to one week of 24/7 microbiostatic protection. Or apply MonoFoil M, EPA registered bacteriostatic, fungistatic and algistatic finish (EPA no. 90856-2-92366) for up to 3 months of 24/7 microbiostatic protection.
Electronics such as tablets, touch screens, keyboards, remote controls and ATMs. Consider putting a wipeable cover on electronics. Follow manufacturers instructions for cleaning and disinfecting. If no guidance, use alcohol-based wipes or sprays containing at least 70% alcohol. If applying long term microbiostatic protection with MonoFoil D or M, lightly spray solution on surface, allow to dry, then repeat 2 or 3 more times. Or apply solution to a microfiber towel and apply to surfaces, allow to dry then repeat 2 or 3 more times. The goal is to achieve the 10 minutes of dwell time.
Workers must be trained to recognize the symptoms of COVID-19 and be provided instructions on what to do if they develop symptoms. (www.cdc,gov)
Cleaning must be performed using the proper Personal Protective Equipment (PPE), including fit testing, proper donning (putting on) and doffing (taking off), and how to properly dispose of used PPE.
Workers must be trained on the hazards of cleaning chemicals used in accordance with OSHA’s hazard communication standard (29 CFR 1910.1200).
Workers must comply with OSHA’s standards on blood borne pathogens (29 CFR 1910.1030), including proper disposal of regulated waste and PPE.
Make sure to check with your insurance provider to ensure that you have the proper coverage.
Cleaning Oriental Rugs On-location
In rare cases it may be necessary to clean rugs on-location (i.e. customer will not allow you to remove the rug from their site or sight). Keep in mind these additional concerns. Proper dry soil removal is go¬ing to make a mess. You may have to do it outside or cleanup afterwards. The floors must be protected from water and cleaning agents, dyes may bleed during cleaning or drying. You may need to take ex¬tra measures to ensure fast drying. You may have to return the following day to inspect results, make corrections (while explaining why this is nothing to be concerned about) and pick up drying equipment. Floor cleaning or restoration may now be required. We do not recommend on-location cleaning of rugs, as your primary mode of operation.
If you have to, first complete a thorough inspection of the rug(s). Test for colorfastness. We do not recom¬mend cleaning bleeders or other “problem” rugs on-location. Next, set up a work area. It needs to be a clean area and it also needs to be protected from any damage from your cleaning activities. Remove dry soils as best as you can on-location.
On-location rug cleaning is best accomplished with dry cleaning. For decades, rug cleaners have found the Ultra Dry System effective and satisfying for their customers. This is also a great system for cleaning rugs which cannot be immersion cleaned (i.e. cloth backed rugs & composite rugs with shrink¬age issues or rugs too large for plant and pit clean¬ing). Pre-spray the face pile and fringe with Ultra Dry Natural & Fine Fibers. Work in with hand groomer or nap brush. Allow a five to ten minute dwell time, but do not allow the rug to dry out. Reapply Ultra Dry if necessary.
Low moisture rinse the rug with Ultra Catalyst Natural & Fine Fibers solution. Mix Ultra Catalyst at 16:1 (8 oz./gal.) with warm (100° to 130°F) water. Submerse Ultra Clean Pads into the Ultra Catalyst solution and wring out excess solution with a pad squeezer. Place wrung out Ultra Clean Pad on the heaviest soiled area of the rug.
Immediately spin Ultra Clean Pad over the entire rug surface and fringe with side-to-side overlapping passes with a low speed (approximately 175 rpm) floor machine. Clean up to about 50 square feet, then flip the pad over and reclean area just covered, put aside spent Ultra Clean Pads and wring out a new pad for further cleaning. Do not reuse soiled pads until laundered. Never place soiled pads back into Ultra Catalyst solution, always use “new” clean pads. Never run pads on dry rugs.
Comb out fringes with a fringe brush, groom the face and speed dry the rug with air movers. If fringes need more attention, use Fringe Cleaner and /or Fringe Whitener.

Fragile, Problem or Weak Rugs
Dry Cleaning can be a great tool in your arsenal of cleaning methods, allowing you to clean rugs that others turn down or worse, damage. Some complain that dry cleaning does not remove water based spots and soils, but tricks of the trade come into play here. Pre-treating with Sublime helps to remove water based soils, and improves cleaning results. Experienced dry cleaners know that water based soils often wick up during dry cleaning just like they do in wet cleaning. Upon post cleaning inspection, spots and soils will often wipe off easily with a damp cotton towel. For best results use diluted LST (8oz per gallon) solution on a wrung out towel to wipe off wicked spots and soils, some cleaners, damp wipe the entire rug pile with LST Solution. DO NOT OVER WET! Towel dry to finish, avoid over aggresive agitation. Fringes may require more cleaning attention. See ” How Do I Clean Fringes.”
Even the most fragile textiles can respond well to dry cleaning. Silks do not lose their hand and bleeders behave and hold onto their colors, fragile rugs survive cleaning and old rugs live on. Dry cleaning is more expensive, and customers are accustomed to paying more for it. Many cleaners charge in the $10.00 to $20.00 per square foot rate for custom dry cleaning. Note also that applying a moisture barrier like Flurosolve is a good idea on those moisture sensitive rugs. Flurosolve will help protect the rug from water based soils and spills. Make sure to offer Flurosolve on every “Dry Clean Only” rugs as clients will appreciate the added protection.
Alternative Dry Cleaning method: Absorbent compound As noted above, some rugs will crock or bleed with solvent only cleaning. Absorbent compound may be an option. Animal skin rugs and rugs made with leather may also be good candidtes for absorbent compound, and some people like this method from some unknown reason. Complete a through inspection of the rug(s). Document all pre-existing damage, and consider having a Release Of Liability form signed. Dust or remove dry soil as noted above in paragraphs 3 and 4. After dusting, we would normally pre-treat the rug with a cleaning solution, but this may not be an option on difficult crocking and bleeding dyes. If however water based solutions will not cause problems, as with most animal skins and most leather, pre-treat with your LST solution of 5 ounces per gallon of warm water (100 degrees f to 115 degrees f). Spray apply lightly, Do Not Overwet. Work in solution with gentle agitation. Allow dwell time 3 to 5 minutes, then apply your dry compound (host, drymatic, capture, etc.) follow manufactures directions. After drying, throughly and meticulously vacuum up all dry compound and soil.
Fringes - Cotton
Always pre-inspect for this damage by pulling on the fringe in several areas. Also look for signs of bleeding, browning, physical damage, old tea dye, mold and dry rot. Some cleaners charge an additional (i.e. $2.00 to $7.00 per foot) fee for fringe cleaning. Remember that many believe, the finer the fringe, the finer the rug. So, the finer the fringe cleaning, the finer the cleaner. Clean the rug first. Often, good cleaning on the entire rug will result in nice clean fringes. To improve your odds of getting clean fringes with your first cleaning, pretreat the fringes with Fringe Cleaner. To prevent browning, immediately after cleaning spray with diluted Rug Soure, comb out fringes with a fringe brush and speed dry.
Sometimes fringes will need more attention after normal rug cleaning. Use a product designed specifically for cotton fringe cleaning. Avoid products using oxidation, the majority of products out there have oxygen producing chemicals in them – do not use these products – they permanently damage rugs. Proper chemistry for cotton will use reduction, the exact opposite of oxidation. Mix up a small amount of Fringe Cleaner with warm water (100�f to 120� f ) as per label directions. Mix up only what you will use as unused solution should be discarded after four hours. Label directions are as follows:
- After inspecting fringes, dust, brush vacuum or blow-out with compressed air.
- Pretest in small inconspicuous area.
- Pretreat oily, greasy, or heavily soiled fringes with Sublime or other anhydrous solvent prespray to break oily bonds.
- Dilute Fringe Cleaner at 4 to 1 (32oz./gal) with warm water.
- Carefully apply to fringe, knots, and kilim strip only – avoid face fibers. Use paint brush, sponge, upholstery brush, or other application device. Agitate by tamping or brushing as construction allows.
- Hot water extract with clear, clean, hot water using a fringe cleaning tool or other extraction device. Use extra vacuum only, passes.
- Treat clean fringe with diluted Rug Soure to prevent browning and to accelerate the cleaning action of Fringe Cleaner.
- Comb out fringe and dry as fast as possible.
Fringes - Heavily Soiled
Fringe Whitener covers over discolorations without damaging the cotton fibers. Some rugs have fringes that are henna, antique or tea dyed.
Sometimes this color is removed during cleaning. You can replace this color loss with Tea Dye, or use it when white fringes are not wanted by your customer
Fringes - Other
For wool and silk use Ultra Dry Neutral pH, simply spray on fringe and groom in. Allow five minutes of dwell time. Then clean as normal. For synthetic fringes, use a pre-spray solutions appropriate for the fiber. Often cleaners find Ultra Dry Original to be a great fringe cleaner for synthetic fibers.
Hand Tufted Rugs
- Check for latex odor and advise customer that it will not come out.
- Stenciling. Grin the face pile and look for stencil ink on the primary backing at color
change areas. Look on the back of the rug. Many times the red or blue stencil will have
already bled into the secondary backing. Turn down rug or surface clean only.
- Color run. Some rugs will be susceptible to color bleeding. Test for colorfastness, both
crocking and bleeding.
- Check squareness of rug. Is it misshaped?
- Never fold or crease a hand tufted rug, especially when wet, as it will leave permanent
marks or even delamination.
- Avoid aggressive agitation or heavy rollers as they may delaminate the rug.
- The latex used decays over time and leaves a powdery residue on the customer’s floor.
this decay will make the rug limber and weak. Look for delamination.
- If cloth backing is delaminated from the foundation or the latex is powdery, quote cost and
get approval to replace cloth backing and re-latex.
- Look for pulled tufts and voids.
- The fringe may be unglued: hems can come un-sewn or un-glued. Quote repairs before
- Talk about the staining and soil on the backing, since the backing is not seen, we will
clean but, we have low expectations on stains and watermark removal.
- Make customer sign a release.
- Air dust or use a vacuum only. Vacuum thoroughly. Do not put through a duster or tumble dust.
- Spray with Sublime including fringes, if oily soil is present.
- Wet out rug with clear, cool water. If the rug fails the crocking test, wet out with diluted
Anti Dye. If it fails the bleeding test, wet out with Dye Release Solution.
- Apply diluted LST over entire face pile of rug. Do not apply to backing.
- Work in with hand brush if the rug is weak, or use shampooer, cimex, or other method on
fringe and face pile only, not on backing.
- Rinse rug with clean water front and back.
- Squeegee, extract or centrifuge to remove excess water.
- If using a flat bed washer, run through as normal.
- Groom pile and fringes.
- Flat dry, face down, with air movers blowing across the back to speed up the drying

11. During drying, run a weighted roller over rug to help soften the leather. Reapply diluted leather conditioner if necessary.
Moisture Sensitive Rugs
Some rugs can be damaged with over wetting. Lower moisture methods can avoid problems with cellulosic rugs that are likely to brown, composite rugs that may have differential shrinkage, latex backed rugs or hand tufted which may suffer from latex migration, rugs with ink stencils which can bleed, secondary backings which can shrink or water mark and rugs which are not very soiled, so therefore not requiring deep, aggressive cleaning methods.
Bonnet cleaning with LST has proven to be a very good method for dealing with the above mentioned cleaning challenges. You can save yourself and your customer untold troubles, plus, you can make tremendous profits using LST. First complete a through inspection of the rug(s), (see “Rug Inspection”) document any preexisting damage, and consider having a release of liability form signed. Remove dry soils with your best method of dusting (see “How to Perform Dry Soil Removal”). Prepare LST solution by mixing 8 oz. of LST into each gallon of warm (100� to 115�) water, and place into a pump-up or electric sprayer with an 06 size jet. Spray apply LST solution to the entire face pile of the rug, do not over wet. Include fringes too. Using a standard rotary floor machine (175 RPM) with pad driver and bonnets or pads, or a Cimex machine, you can obtain safe and effective results. Spray your bonnet or pad with LST solution to ensure that both the carpet pile and the bonnet are lubricated with LST. Spin bonnet over the rug surface. After cleaning approximately 30 to 60 sq ft. flip bonnet over, spray with LST solution, and continue cleaning. Once both sides are soiled, use a fresh clean bonnet, spray with LST and continue cleaning. Usually only 2 or 3 bonnets will be required to clean a 9″ x 12″ rug.
Remember to get the fringes too. If you find that the rug is too wet, you may want to spin a dry bonnet over the pile surface. Be careful to not over agitate and watch for shedding, do not over dry or over agitate rug. Speed dry with air movers or place in dry room to speed drying. Fringes may require more cleaning (see “How To Clean Fringes”) after the rug has dried. Because LST will physically trap soils, post drying vacuuming is required. Simply dry vacuum the rug pile after drying is complete, use a high quality, high performance vacuum for best results.
Rayon Viscose Rugs
1. Test and inspect rug. Complete pre-inspection form and photograph rug. Note all
pre-Existing conditions, including:
2. Look for yarn slippage.
3. Document texture issues.
4. Look for yellowing and other discolorations.
5. Test for bleeding and crocking.
6. These rugs often become stiff and change texture if not washed with proper chemistry
7. Avoid any aggressive dusting. Do NOT air dust.
8. Must have customer sign a release of liability waiver before washing.
- Gently dust or vacuum with care.
- Wet out rug with cool water and Rayon Rug Shampoo mixed at two ounces per gallon.
Apply to both sides of rug. Allow two or three minutes of dwell time.
- If colors/dyes crock off, apply Anti Dye heavily.
- Apply Rayon Rug Shampoo mixed at eight ounces per gallon. Apply to both sides,
- Work in with rotary, Cimex, hand brush or other method, to shampoo into rug.
- Rinse with cold, clear water until rinse water is clear.
- Squeegee, roll, ring out, extract, centrifuge or use other method to remove as much
excess water as reasonably possible.
- Groom pile with the primary lay of the pile.
- Speed dry the rug. Rayon is very slow drying and some will brown or discolor during
drying.Speed dry as soon as possible. Dry upside down to prevent browning to the face.
If hanging to dry, ensure proper spacing to avoid rugs flapping against one another.
- After drying, groom again, going with the primary and secondary lay of the pile.
- If the rug pile is stiff or distorted, lightly apply Silky Soft Solution and groom again. If
yarn slippage is an issue, use the hand wash brush for silk to groom.
- Tactfully advise the customer to never buy rayon rugs again.
1. Always inspect and pretest. Note all pre-existing damage including:
A. Texture change issues
B. Color migration issues
C. Yarn slippage issues (avoid aggressive over grooming or brushing)
2. Air dusting at high-pressure can carve or streak the pile. Lower the air
pressure of dusting tools.
3. Avoid alkalinity. Do not use high pH. Use only acid pH solutions. The isoionic point for silk
is 4.5 therefore the pH of 4.5 is your goal when cleaning silk.
4. Do not use acid rinses or cleaners that contain phosphoric acid as this
specifically damages silk.
5. Work quickly. Wash silk rugs fast and efficiently.
Wet cleaning procedures:
1. Dust rug, avoiding high pressure when air dusting.
2. Spray the entire rug, including fringes, with Fringe Pretreatment or pre-wet with cold clear
water. If colors are crocking, pre-wet with AntiDye Solution. If colors/dyes are
bleeding, consider dry cleaning instead of wet cleaning.
3. Apply Silk Rug Shampoo solution to the entire rug, including fringes, front and back.
4. Hand shampoo or use rotary, Cimex or other method to work solution into the rug, front
5. Rinse with cold, clear water or run through flatbed washer or other system.
6. Squeegee, roll, ring out, extract or centrifuge to remove all possible excess water.
7. Groom pile with the primary lay of pile yarns.
8. If needed, lightly apply Silky Soft solution and groom in, going with the primary lay of the
9. If colors/dyes can possibly migrate during drying, flat dry in dry room on cotton towels or
quilts. place upside down, with airflow over the rugs backing. Use heat,
dehumidification or other method to speed dry.
10. After drying, groom again with a silk carding brush. Apply Silky Soft if needed. Groom in
with the primary and secondary lay of the pile. If yarn slippage is an issue, use a hand
wash brush for silk, or other appropriate grooming brush.
Dry cleaning procedures:
1. Dust rug. Avoid high pressure when air dusting.
