Cleaning bath tub stains?

I've been living in an older apartment building for a while now and the stains at the bottom of my bath tub are really starting to bug me!





It's from a bath mat that you would put at the bottom of the tub to prevent slipping. Dirt must have gotten underneath and then stained the tub.





I've tried scrubbing with soap, and bleach but neither has worked. Does anybody know something that would get these stains out of my tub?





I think it's a plastic tub if that helps any.





Thanks guys!Cleaning bath tub stains?
There are three things I would try.





1. Car cleaner and polisher. It is mild and won't scratch the plastic. Lots of elbow grease.





2. Soft Scrub Deep Clean Foaming Cleanser, brand. That sprays on and cleans like crazy. Leave it on for a few minutes and then use a sponge to clean and then rinse off. Hardly any elbow grease, but I've used it on plastic, stainless steel, teflon and it works great. Won't scratch the plastic. Don't let it dry out.





3. Soft Scrub with Bleach, brand. It cleans and doesn't scratch either, You can leave this on for awhile after you apply it with a sponge to let the bleach work and then wash it off. Some elbow grease required. Don't let it dry out.Cleaning bath tub stains?
I use a product called ';The Works'; that I usually find at Acme or Ace Hardware. Think it's about $6 a spray bottle but it really works on hard water %26amp; rust stains. Usually don't even have to scrub. Just give a good soaking and let set 1/2 hour or so. Repeat if necessary. Be sure to keep a window open or if there is no window, keep the door open and a fan going. Leave if the fumes get too bad, which they can. Test it first on a small corner; not sure about how it will react with plastic. Good Luck!





I'm looking for something that will help with laundry water.
1.Get rid of calcium deposits on faucets by soaking a cloth or paper towel in white distilled vinegar and wrapping the area tightly. Let this sit for a couple of hours or overnight.





2.To remove grime, mildew, and scum from the tub, tile, shower curtain or door, wipe with undiluted white distilled vinegar. Rinse with water.





3.Spray shower doors with full-strength white distilled vinegar after you鈥檝e squeegeed the glass, or before you step in and turn on the water. It will help release the hard water deposits so they don鈥檛 remain on the glass.
