How do I get this shower stain out?
New apartment has these stains in the shower alcove. Please please please give suggestions how to remove it.
Pictured is everything I have tried so far (not mixed together). Blue stuff is Dawn, baking soda and vinegar. I have even tried sanding it and the stains seem to be deeper than that. I’m not worried about damage because clearly the landlord didn’t care enough to fix the stains from the last tenants. I’m not sure what material the tile is.
