Bleach marks on wetwall

[Federiica]

My shower had black mould in the corners because I am the only one who ventilated the room 😥

I squirted lemon bleach down both corners and now my wetwall is stained yellow. I don't usually use bleach. I don't know how to get the yellow off. I don't know if the colour is the stain from the bleach or if the bleach has damaged the wall itself.

Is it even called wetwall? The surface you can have instead of tiles.

Bleach is awful for mould, you should use a mould and mildew remover.
Apparently white vinegar is supposed to remove bleach stains on walls, but I’m not sure if that includes the type you are talking about. Is it plastic?

It's been proven that harsh chemicals such as bleach and ammonia aren't effective in removing mould. The problem with bleach is it does nothing to remove the mould. Instead it bleaches the colour of the mould, giving the illusion of a mould-free surface
