I AM A CARPET STAIN REMOVER
I remove bleach stains, coffee stains, kool-aid/Red Stains, food stains, grease, paint or oil stains, chemical stains.
I remove this pet vomit stain from a large dog on a very expensive wool rug. Hot vomit alkalizes after about 2 months and browned the wool rug. I removed the brown and added back the lost color! This is a complicated wool carpet repair, but very effective.
