Best bathroom tile, soap scum and countertop cleaner I've ever used -- and it just wipes away. This stuff removed stains, dirt and other marks that I couldn't remove with Comet no matter how hard I scrubbed or how many times I tried. Doesn't smell the best, but it works like no other. And the smell goes away in a couple of hours.
Chalk will remove grease stains from clothes. Simply rub the stain with chalk, then toss in the wash as normal.
