Drain Cleaner Stained Tub

Should I remove the drain cleaner steam color on the side of the tube? 3

I used a drain cleaner to open the blocked drain, the label says sulfuric acid. It works fine without any other plug, but the reaction vapor stains the surface of the tub. How to remove this stain? I've tried detergents and not all of them work.

My absolute favorite: baking powder. It's cheap and easy to test.

Make a paste and rub.

I doubt the surface was scratched, but it won't hurt.

GL!

I had the same problem and I found out that the bowl cleaner removed the stains. You may have tapped the bathtub, and if so, nothing will work because the bathtub is broken. In my case, the only thing I found was a bowl cleaner. Be careful because if it comes in contact with the skin it can burn. I opened the window, used the fan, put on the mask and long rubber gloves. I closed it and he left immediately. Rinse with water.
It can't be.
Gutter cleaner destroys ink. Not because it is black or stained.
Color does not exist. It's ruined.
