Remove Yellowing on Shower Walls

[Diver007]

I've got a RoadTrek 210 shower Which has Yellowing on the fiberglass walls. Has anyone found a reasonable way to clean it and remove the stains?

if it's from water minerals/ rust I'd try CLR


if is seems discoloured due to age I'd try a "magic eraser"

Interested in replies. I’ve also read that hydrogen peroxide sprayed works but have not tried it. I thought my shower pan was almond colored until I removed toilet and sound it snow white underneath

I use diluted Softscrub for things like that but it is abrasive like old time rubbing compound we used on old cars for fading paint. I would certainly try anything on a small spot to see what happens.

If you get too aggressive with Softscrub it will take the gloss off the finish.
