It keeps getting dirty. Bathroom only has a vent fan.
Stuff to clean both dirt and some mold?
Saw a guy in Costco selling a kit for $50 that he claims cleans
anything. Did not buy, but may since Costco will take it back.

First effort should be directed to removing plain dirt and soap scum. I
have used 3M scrubber and Dawn for
soap scum. Scrubbing Bubbles is very good for regular cleaning. Razor
blade scraper, with caution, is good
for heavy soap scum. Once rid of soap and dirt, regular cleaning with a
little bleach will take care of mold. I
leave my shower curtain open and stacked in the middle of the rod to
promote air circ. If you have grout or
caulk lines that trap water, you might want to repair or replace them.
