I had my carpets cleaned the other day.....various sick-cat messes....won't go into detail...I'm sure you get the picture....:-)
but anyway, the carpet cleaner guy told me that for pet messes, one should use an acid (vinegar) to clean up the acid messes (urine, vomit, etc), NOT an alkaline cleaner (like a soap). I was wondering why my clean-up jobs always left more of a mess than the cat had!!!
Just thought I'd pass along this info. as I am sure we have all had to deal with this issue!!!!
