A mixture of bleach and water will take it off.

As an Army wife, we've lived in many apartments and in the past I've used Borax (20 Mule Team) mixed with water, about 1/4 cup to gal. water and scrub with stiff brush rinse. If that didn't get it all, mix Borax into a paste and apply, leave for an hour scrub and rinse well. The other way is scrub well with a thick mixture of Baking Soda and water, leave on for about an hour, the with a spray bottle filled with plain White Vinegar, spritz well, let it bubble for about 15 - 20 minutes scrub and rinse. If this doesn't work, I removed all seam grout in between tiles and applied a new water proof grout that you can get at any home improvement or Walmart in plumbing.

Good Luck as it's cheaper than new and much healthier to breathe! :~)

What kind of tile? Maybe try CLR Or Wink rust remover depending on tile material

I have always used a vinegar water mixture weekly or when ever I bath , spray on walls and glass doors, rinse. Have never had scum or mold build up and shinny clean shower. Vinegar 1/2 c - water 12 oz. spray bottle. Leave for few minutes then rinse and wipe. If build up is bad increase vinegar and repeat.

I used bleach in a spray bottle but make sure you have really good ventilation. It can burn your lungs.
