I have dirt stains from foot in my shower, and a ring inside my tub tub. I have tried scrub it and soaking it with bleach but it hasn't worked. How can I remove these stains? Thank you
How do I remove tea stains from towel?
Answers:    I hold those at my house too. I usually spray 409 all over later let it set for a couple minutes. Then spray it again and use a raining Mr. Clean magic eraser entry. Most of it should come off unforced but for some stuff you just own to scrub hard.
