This is the best smell/stain remover I have found after over a decade of trying different products, and BY FAR the most simple. Literally just douse the carpet and let it dry. First round I had to do two sessions but it completely cleared EVERYTHINGGG!

I tried something else recently that was highly recommended online, due to having had run out unknowingly and needing it immediately and just no. Making sure I have some on hand for back up now always.
