I'm using the detergent form of F10 and its been working pretty well for me. I don't even rinse mine out as long as theres enough time to dry. I've been using it between my SO and I (we both have snakes) and it comes out to like 2-3 dollars per bottle of product we mix. Mind you, each bottle lasts like 3-4 months at a time so I think it's well worth the investment.
