Fugitive dyesIf the red is shown to not be colorfast during your

dye test, it could bleed from improper exposure to water from a flood or a poor cleaning attempt.

Your dye testing process will show you the potential risk of dye migration during cleaning, and you can de-termine what dye stabilizing solution and cleaning solu-tion to use.

‘Excess’ dyeIf the rug has never been cleaned previously, there

might be a bit of “excess” dye in the fibers that may wash out on the first cleaning, just as with a new color-ful shirt in the laundry.

Or, if the rug is from a weaving area that does not have access to a thorough washing of the wool prior to the weaving, there may be excess dye in the wool wait-ing to be released.

You see this in some American Indian weavings, some Afghanistan rug weaving and some other tribal weavings where water may be scarce.

There are a variety of reasons a rug might “bleed” on you.

Let’s go through different scenarios that you, as a professional cleaner, may encounter. This knowl-edge will help you identify, and then avoid, potential problems.

Here is a picture of a wool and silk Nain rug that has bled, where the red dyes have migrated into the neigh-boring off-white areas.

What could create this type of dye migration? Several things could have happened.

CARPET AND RUG CLEANING

Yes, we are speaking of pet urine, which starts off as an acidic stain, and then turns alkaline over weeks and months.

If it is not cleaned up right away, this can create permanent dye damage that deval-ues the rug.

A rug may have colorfast dyes, but all of the areas with urine exposure may bleed no matter which steps are taken to prevent it.

It’s important if you are washing a rug that has pet stains to have a release so that the owner understands that any dye dam-age existing from the pet urine contamina-tion is not reversible, and although you will take great care in washing the rug, you will

The next photo is an example of an India rug that has been tea washed because it had bled.

Another common technique to “color up” a rug is to use ink to hide flaws or to enhance the colors of a rug with poor qual-ity fibers or dyes. The problems with this type of “painting” of the rug today is that if it is using ink, this often bleeds out when wet because a dye stabilizing solution is not going to work on ink.

A proper dye test will show you if ink has been used.

Something else that can be “added” to the rug is done by “accident,” and you can see the result in the next photo.

Over-dyed applicationsSome rugs are given an “over-dye” ap-

plication after the weaving process.The most common is a “tea wash” treat-

ment, where a brown dye mixture is ap-plied to the rug to make it look older, or with softer colors. This is also called henna-wash, or gold wash, or antiquing.

As with anything, there are both poor quality and high quality versions of a tea wash.

In the poor quality, it is sprayed on, and will crock off on to a dry towel during a dye test.

Here is an example of a poor quality tea wash Chinese rug.

A better quality tea wash will hold strong during a future washing, but over time will fade, first most noticeably on the fringe tas-sels (which will turn from beige to white) and then in the rest of the field of the rug over time.

Worth noting is that, sometimes, a “tea wash” is applied to hide flaws, such as prior dye migration or past stains.

It’s important to closely inspect tea washed rugs on the front and back to look for any warning signs. (Concluded on next page)

Rug cleaning concerns

High heat or high alkalinity A colorfast dye may bleed even with the proper application of a

dye stabilizing solution if it is improperly combined with either high temperature during cleaning or high alkalinity (such as with many traffic lane cleaners).

If you plan to clean the rug outside of recommended pH and tem-perature ranges, then always test the dye with that temperature/alkalinity to make sure you do not create dye damage.

Past in-home cleaningsThe biggest problem with in-home cleaning of rugs is the residue

(and soil) left behind in the fibers. If the residue build-up is buffered on the alkaline side, it will lead to

long-term problems to wool rugs. Over time, it can create a “bleeder” of a rug with acid dyes. It may clean up decently the first or second time, but on the third time it can unexpectedly bleed on you, and this is why. The buildup caused the dye problem.

Natural fiber rugs are meant to be washed, so it is best to remove them from the house in order to clean them properly.

making any unintentional marks on the front of the rug with your dye test (or if the rug is so filthy you cannot get to the dyes from the front to test them).

Walk from the bleedersWith the right training, and the right so-

lutions, it is possible to wash rugs that are “bleeders.” But if you do not feel confident in that area, it may be a better choice to seek out someone else who is. Leave it to the rug plant professionals.

If your dye tests come up as troubling, most rug plants have the chemicals, tools, wash system and water removal equipment to handle the trickiest textiles. It’s always good to have a plant you can subcontract to when you know you have a bleeder on your hands, and most will extend a professional discount to you.

If you do take on the risk yourself, be-cause you feel you have the right training, solutions and tools, then at the very least send some photos to others in your net-work to get any additional insight before you begin.

It never hurts to seek out support before your work begins, and can end up saving you from a disaster if you happen to have some knowledgeable cleaners in your cir-cle to give you some guidance in the pro-cess. CF

Test, test, testMost rug dye migration disasters can be

avoided by thoroughly testing the dyes of the rug before you clean it, so you know which rugs to run from.

To see a video on how to properly test for potential dye problems, visit www.Clean-fax.com/DyeTest.

1. Test with hot water or a high pH spotter. It is important if

you are testing the front side of the rug that you “grin” open the fibers so you are test-ing the entire fiber, and not just the “tips” of the fibers.

2. Test with your dye stabilizer or dye lock solution as directed. If

your first hot water test shows migration, then you test with your stabilizing solution (acetic acid, citric acid, etc.) to see if it also migrates with this test. If there is no improve-ment in the transfer during the test, then you need to look more closely as to whether you have bad dyes on your hands, or perhaps ink.

3. Test the back of the rug, too. Sometimes the bleed is not com-

ing from the face fibers, but coming from dyed weft threads. Test the back of the rug to make sure the wefts will not bleed. You can also test the back if you are afraid of Circle 209

Are you insured?Rug cleaning is a tricky business. Sometimes, your policy may cover

the rug in transport, in case of theft, or in case of any damage due to ac-cidents while in your care (“care, custody and control” coverage), but not if the rug bleeds or is damaged during the cleaning process.

Sometimes, a policy may cover a rug when it is cleaned in the home, but not if it is cleaned in a rug cleaning facility (or vice versa).

It’s important to find out your coverage before you need it. Ask your agent what is covered and what is not, so that you know which risks you are willing to take, and what you are not — or if you want to add additional coverage to your work.

Usually when cleaners find out they are not insured is when they need it the most.
