Chemically Sensitive Rugs: Dangers

This article was originally published in Cleanfax.

There are four main concerns with cleaning technicians attempting to deal with chemically washed rugs.

1. Color fade and change from sun or spot removers

These rugs fibers, especially the luster and antique washed ones, are damaged fibers. Those more aggressively-treated rugs become much more sensitive to sun fade and also more prone to color change with use of some spotting solutions.

Avoid drying these rugs in direct sunlight. Always test spot removers in small areas before attempting any larger use.

2. Pile distortion and fiber breaking


High sheen wool rugs have fibers that can easily get distorted and break from the use of extractors, brushes or other tools. They also can be damaged from foot traffic in a way that creates shadowing that may not be correctable with washing.

Avoid heavy scrubbing on high sheen wool rugs. Make sure that your extraction strokes are with the pile direction, not against it. Wands with a Teflon head will help prevent fiber breaking. Use softer brushes for grooming, and a gentle hand with tools going with the grain. Never rake the field of these rugs with a carpet groomer.

3. More susceptible to staining

With luster and antique washed rugs, the protection of their wool cuticles has been compromised, and this makes them more susceptible to permanent staining. Be aware of this before you promise a client that spots/spills are “no problem.” They may be a problem on a chemically washed rug.

With tea washed rugs, it is not unusual to have a spot remover remove the brown dye treatment and create a bright white area on the rug. Remember, these applications are not permanent, so stay gentle in your cleaning solution choices.

4. Odor and sensitivities

Some chemically washed rugs have residue of their treatments absorbed inside the rug’s cotton foundation fibers. I have had several consumers contact me regarding having chemical sensitivities to “tea washed” rugs from India after flood incidents. These rugs tend to have thicker foundation wefts that may not release the solutions as easily as thinner fibers would.

If a rug is woven (you can see the knots on the back side of the rug), most odors can be removed through fully washing the rug and using the appropriate solutions targeting the type of contaminant causing the odor.

Inspection is the best protection. When a rug is covered up in soil, it can be a surprise when cleaning uncovers “problems” like pile damage, dye damage or discolorations due to past chemical wash treatments. The more time you spend inspecting a rug, the less time you will spend trying to correct problems that are not your fault.

Determine if a rug has been chemically washed, and then discuss those issues with the client before the wash. When you address the issues beforehand, you are educating the client, and also protecting yourself in the process.
