Hi there. How come part of my walk in shower base has got a yellow stain on it. Is the material that was used on it cheap? Also the same yellow stain is on my toilet seat
...the mark at the bottom of the shower door might be a rust stain, from screws used on assembly. BZP will rust if kept damp. If you can get a pure phosphoric acid rust remover (Jenolite liquid used to be, but I believe is discontinued) and tape cotton wool or kitchen roll against the stain, wetted with acid, it will clean it off. But you will also need to remove the rusty screws and replace with stainless.
