Discoloration in Tub Surround- What to do?
Hello, I have been researching for hours and all attempts so far have been fruitless.
I moved into a rental duplex with a yellowing bathtub surround. It's an unknown material in panels with strips over the seams. It's quite yellow compared to the tub and the tile around it. So far nothing has worked to restore it to white. Bleach doesn't work, tile cleaner, comet, toilet bowl cleaner (saw online and tried it), not even goof off.
Replacing the tub is not an option. We don't own the property.
1. Is there anything I can do to restore these panels to white?
2. Can anyone take a guess at what it is made out of?
