yellow carpet

[lust1kiddo]

I used formula 90 on a comercial style carpet in a store and a day later..part of it turned yellow. I should acid rinse to get rid of it right? I have all fiber textile rinse from chemspec and also have pro chem axiom rinse. Just wanna make sure I am in the right ball park.
Thanks!!

YES

5% acetic acid (vinegar) will usually do it. Smells like a pickle till it dries.

So should I use the acid? I have that too. Just re rinse the rug with it?

Just spraying the all fiber rinse and grooming in will help with the yellowing if it is due to high pH or over wetting. Then, give it a quick rinse.

If the store has a black to parking lot or is located right off of the street, the yellow might have been there hidden by the soil. The petroleum in the tar can cause olefin to turn yellow. I haven't been able to remove it 100% of the time.

I fixed it with chemspec all fiber rinse. Looked pretty good when I left.
Thanks Guys
