In my new place, there's a semi-transparent grouting/glaze over the corners of my shower - and there's mold growing beneath them?
Is this normal? How can I fix it?
I had a similar problem and here's what I did.
To maintain a mold/mildew free shower I use Arm & Hammer Clean Shower every day after I take a shower. I spray the stuff around the shower cabin right after I get out of the shower. It has a nice scent and it does a really good job keeping mold and mildew out!
There's no way to get around re-caulking to fix this. Just realize that mold can be growing within the walls (particularly on drywall that isn't mold resistant). This means you may want to consider switching to an opaque caulk and accept that this will be a reoccurring process.
