bathtub stain

I used liquid plumber in my bath drain and within 20 minutes a bad chemical smell came from the drain. The reaction caused the tub to turn brown/black (the tub is salmon colored)where the glaze was removed. After flushing the tub I sprayed it with bleach and that removed most of the stain but several places the black marks remain. Any ideas on how to remove this? And what might have caused this to happen in the first place?

Read the directions on the liquid plumber.
You may, and this is a big may, be able to remove the rest with some tub and tile cleaner (commercial grade) that is available at Home Depot / Lowe's. This is sold under the Zep brand name.

Bathtub stain

You probably delaminated or etched the bathtub in this area with the acid drain opener.

Here is the test. Dry the surface area you described.
Take a coin, or a key, and firmly drag if across the area.

If it leaves a pencil like mark then the pours are open and no matter what you do this area will now be Susceptible to staining.

If you take that same key or coin and drag it firmly against the outside of the bathtub or an area where there is no wear you will see that no matter how hard you press it will not leave a mark.

Always read the label on these products first. For general maintenance and helpful hints visit
