As it's a Resolve product, it work really well on a lot of differents stains and removed them 90% of the time (some are most difficult like grass ones), but I have the feeling with this double pack that too much product is coming out of them sometimes. It's so wet after a small shot....

Didn't meet up to my expectations. Did not remove all stains and is not that handy to use. The price/quality is a lot better on the non-dual resolve spray version.
