For removing rust stains in your bathroom, cleaning your countertops in your kitchen, and just about anywhere that you need a little muscle, Bar Keepers Friend is fantastic. Bar Keepers Friend is also good at polishing brass, copper, and chrome. Just use little on a damp, clean cloth. Never use with any abrasive scrubbers, because you can easily scratch the surface. Just rub, rinse, and wipe dry to prevent spots.
