Forum Title: Cotton couch - vinegar cleaning solution
We recently had our cotton couch cleaned by a upholstery cleaning service and a day later our cushions appear to change from green to orange. We advised the cleaning service and was told that the issue is related to sun fading. We know for a fact that the couch was not oramge before the cleaning. The outfit advised us they use a vinegar based cleaning solution. Would this have any affect on the changing color of our couch? Johnny

Johnny, It may be that you have what is known as an indicator dye. If so it is acid sensitive and this has brought about a colour change. Though the cleaner cannot be blamed for not knowing of this potential problem, a fully 'professional' cleaner should know of the rectification procedure.

John, It could be a dye that caused the problem. Do you notice the color change everywhere on the couch, or just in spots? If you still have some of the cleaner, or can get some, you could test the pH and see if that potentially damaged the couch. PH strips are pretty cheap. Did the cleaner offer to do anything about the damage? I'd be pretty upset if that happened to me. Best of luck resolving the issue.

Bungee, From the orriginal post it is clearly a low pH cleaning agent. This problem is becoming increasingly common and I have corrected and reversed the colour change several times of other cleaners. It does require some understanding of colour repair so is not something to be tackled on a D.I.Y. basis.
