I tried this stuff. It was expensive but i needed somehthing for the awful odor in the truck. as far as the odor in the truck is concerned it has only worked about 1/2. I think i might have to do a shampoo and spray it while it is wet to really get down in there. but................
LET ME TELL YOU....... I tested it also on a spot in an unused room that Ahia liked to sneak off and pee in the night before she was trained. this carpet I am not worried about due to the fact we are going to take it out of there when we remodel. so i have only used the steam cleaner in there.(no treatments of any sort). the zero odor took out the stain. completely!. It took 3 times treating but it worked. I treated and dabbed on it with a towel. then used the steam cleaner. you can't even tell where the stain was.
I was interested to see if it was because I was using the steam cleaner on it so many times . so i took another stain treater on another spot the same amount of times. you can still see the stain. so i used another spot to test the same amount of treatments with another product. same result.
the directions does tell you you might have to treat stubborn spots a few times for it to work. that i did have to do.... but the end result is if I was thinking about replacing that carpet because of pee stains, I would not have to do that by using this stuff.
I forgot to add the carpet is white. spots are easily seen.
