Hi all our bathroom is the lovely 1970's tile type and we have mildew issues with our grout in the shower. I am struggling with finding a way to effectively clean it, I want to avoid bleach, and I have heard that vinegar can actually sort of eat away at grout (has anyone else heard this). Vinegar and baking soda are my usual go tos any thoughts suggestions or ideas? Thanks!
How to clean tile grout in bathroom?
This is totally not eco-friendly-- but it works great. I have 1700 sq feet of tile with white grout (not a smart choice). After trying many things, I discovered that sprinkling a very light amt of Cascade dishwashing powder on the grout and scrubbing with a stiff brush gets it off very easily and really brightens it.
For showers I agree that using hydrogen peroxide would get a great way to prevent the mildew.
Is the mildew in the grout or the caulk? If it's the edges around the shower and looks flexible/silicone-y, it's probably the caulk. I don't think there's any way to clean that other than re-caulking since the mildew is underneath it.Supposedly re-caulking is an easy DIY project. I spray a bleach/water mix on mine which improves it but it still looks awful. I agree w/ the PP that the best solution is prevention (plenty of ventilation, drying off shower after each use, etc, but of course that's hindsight (and a pain, lol. )
ETA if it's the grout I just scrub mine w/ a brush. Vinegar is definitely caustic on grout, but you can apply a sealer yearly, and that really is an easy job.
