The product works well, cleans thoroughly and doesn't seem to irritate my dogs eyes. For the 'de-staining' effect (which i don't do) the instructions state to leave the product on for 3 minutes. I dont do this i just use it to clean and it works fine. When it arrived in the mail it was packaged poorly and the product was oozing out the top. Wasn't sealed with plastic or anything which i thought was weird.
