I'm sorry, I thought I posted a response.
Well, no, the stuff didn't work!!! They say it won't work if you've used previous chemicals on the rug...and I used tons!!! Windex, other pee cleaner, Bissell carpet cleaner, etc. So, if you find someone that never used a chemical on their rug, it might work. But, find me that person who has Yorkies and never put chemicals on it!! LOL
Someone on YT a while back posted about a GREAT pee cleaner that worked wonders. I can't actually find the thread. Anyone remember what the stuff was called?
