I tried everything I had labeled "carpet cleaner" in the house then decided to go for plain old hydrogen peroxide. I did not fear it bleaching the polypropelene fibers. Even if it did, I would rather see that than the yucky brown mystery spots he left behind.
I was equally shocked to see the stains fade before my eyes! At 69 cents a bottle, what a great money saver it was. I just sprayed it on and used a rag to wipe it up after about 15 minutes.
Again, peroxide may fade some colored fabrics but, in this case, I was very happy to see the the stain "fade" with no noticable change in the carpet fibers. I would be real sure my colors would not fade before trying this on a darker colored carpet. For me, it would have meant buying new carpet as bad as the stains were.

What a good idea. But I have a question? As peroxide comes in different volumes,which one did you use?
