I have a customer thats has a pet urine stain on a white wool rug. They first put about 2 cups of vinager with water on it witch in turn made it turn pink. Then they put some pet stain remover on it and then it just spread bigger. I think they put to much water & vinager on it the first time and made the carpet backing (jute) bleed through. What do you guys think, and can it be removed with anything. Thanks alot, Harold

I would clean but explain that no guarantee applies with this combo of urine & wool!

How old is the urine?

Being white, it may already be shot.

If you do decide to try anything, definitely make sure that they are aware it's already stuffed and let you off the hook with any results etc.

Also, don't do it onsite. Take it away to your shop/garage/whatever you have available to you.

I'd go first with a mild alkaline detergent mainly to flush out the many spotting products taht are already on there and then rinse with an acid rinse.

Apply 20vol H2O2 in a small test area and see what happens. The residual pH from the detergent should be sufficient to boost the H2O2.

Thoroughly rinse, and follow up with something like a yellowing treatment... sodium metabisulfite based product. I don't know your brands available to you.

Finish it off with a mild wool approved alkaline detergent, agitate lightly if it will stand that and then rinse using an acid rinse.

Speed dry it upside down if possible with air movers and that should prevent any return of the cellulosic browning.

Chances are, it'll still have a yellowing effect but you never know.

Others may have other options that may work as well or better.
