Title: Doesn't work for set-in perspiration stains
Product review: I have a racing pit crew shirt that I unfortunately neglected for a while and there were some set-in perspiration stains in it. I read that enzymatic cleaners work well for this and this product seemed to get decent reviews so I gave it a try. I soaked the areas in question for 5-10 minutes a few times and put the shirt in the laundry but the stains are still there. It may work for pet odors/stains but doesn't seem to work well for perspiration.
Would you say this review depicts the product in a flattering or unflattering light?
