What products will clean my bathroom shower tile?

what type of cleaner. Store bought or home made?

Straight vinegar in a spray bottle. Spray heavily and leave for a few minutes. If you think it needs it, scrub with a stiff brush, then rinse it all clean.

Equal parts white vinegar and blue Dawn dish liquid. put in spray bottle. Spray let sit and scrub and rinse away. Or use Dawn with ammonia same thing.

I like KABOOM. That's what I've been using lately.

Have you tried Awesome cleaner from Dollar Tree. It is amazing!!

Agree with Catherine- if the crud is really thick then it will need scrubbing, and probably a couple of rounds at it with a thorough rinsing of hot water in between.

Comet makes a liquid bathroom cleaner that works well.
