[PandG]

We use vinegar, which was recommended for tile cleaning at our walk-through with the builder. I'm also sensitive to bleach, as someone else mentioned, and vinegar works wonders as a disinfectant!

We keep a spray bottle of 50/50 vinegar + water on the shower bench. We wipe down the shower walls, soap dish, and floor with a large towel after each use, plus always run the fan. We've lived here only 2 months, and so far no mold odor or problem

Good luck!
