We have ceramic shower tiles that I have tried a half dozen different cleaners on but still have not found a way to clean the mold on the grout in between them. I’ve tried the vinegar, dawn, peroxide mix, an essential oil plant-based cleaner, Krud Kutter, etc. and still nothing seems to work effectively. We live in a rental property so this makes me even more anxious because I want to keep it clean! Any other suggestions are welcome.
From what I have heard (since I don’t have a tile shower), bleach is best. You can either spray bleach of the grout lines or I’ve heard that toilet cleaners (with the thin nozzle) can be great because you can apply it to the grout lines easily and leave on for a bit then rinse. I wish I had a better answer for you!
