I have tried.
How to get stains off of shower floor.
Shake the spray bottle to combine the ingredients then spray the solution onto the shower floor over the mold.
Of borax and 2 cups of hot water in a spray bottle if the mold remains.
Wipe solvent off before you rinse the stain to keep the solvent from going down the drain.
Never use any kind of polish or wax on a shower floor or inside a bathtub on the bottom surface or the top of the sides.
Allow the bleach to penetrate the stain for several minutes.
If you have orange stains in your shower try scrubbing the stains with water and a rough sponge.
After letting it sit for 15 minutes scrub the area lightly with a cloth.
Dust the shower floor with a thin layer of baking soda then wet a cloth with white vinegar.
The tile and glass for the shower is new but the pan is original 22 years old.
Floors this dirty looking are no.
If the stain doesn t come off easily lay the vinegar soaked cloth over.
For older stains that are tougher to remove mix together baking soda and vinegar until you get a paste then spread the paste onto the stains.
If the floor of your fiberglass shower is home to tough mildew stains you can remove them with chlorine bleach.
If all the water fails to drain completely out of the shower and instead pools on the floor the lining of the shower can begin to rust leaving a reddish brown stain.
Don t get solvent on plastic such as drain covers.
Scour the mold with a scrub brush let the solution sit on the stain for 15 minutes then rinse with clean water.
If necessary use a nonabrasive brush or cloth to scrub the stain.
Rinse the shower floor with clean water.
Of white vinegar 1 tsp.
Apply a small amount to the stain.
My fiberglass shower pan has a stain presumably from hard water that i cannot remove.
