I have used Oxyclean a lot. Just one time, and it was recent, did it bleach something out. I put a heavy application on a pair of new jeans that Jonah had on. I looked out my mom's window to see him being pulled around by his arms by his cousins. LOL. First time he wore them, and they were heavily grass stained. So, the jeans now have no grass stain, but, small white bleachy looking stains. I put a ton of the stuff on, and left it on.

Maybe a lighter application? The scrubbing does unravel the carpet weave.
