That's why I was thinking of the OSR since it has Sodium percarb in it. I was more concerned about the urine that has soaked into the grout. Probably no big deal, because the customer has done nothing with it. So whatever I do will make a big difference. I have some odorcide, but was figuring go with OSR first and then odorcide.
Thanks for the help. We are definitely going to have hook up Harp.
