So simple...extra power when hand washing dishes.

I purchase pumice-based hand scrub (Lava, Go-Jo, etc) and mix it in a pump bottle 1 part Lava to one part dish washing detergent (I use Dawn). You can scrub anything clean in a flash, and it doesn't hurt your hands! Sometimes I dilute the mix with a little water if I am using concentrated dish detergent. Coffee stains in a grungy mug...No problem! Greasy casserole dish...Done!
If the grocery doesn't have the pumice scrub you can get it at an automotive store.

Hope it saves y'all time as well.
