Hello:
Have a shower stall that unfortunately has several corner seams
that were "caulked" with RTV. Of course, by now they have gotten a bit
moldy.
Have tried all the common bathroom stall type cleaners on it, but no luck.
My guess is that the mold, while probably not on the surface, is not very
deep. But, of course, I'm not too sure of this.
Is there any product that stands a chance of cleaning the RTV, that won't
damage or de-glaze the tiles ?
Really don't want to have to rip out all the RTV if I can avoid it.
Thanks,
Bob

Have you tried Chlorine bleach?
I would just go ahead and remove the RTV and replace with tub and tile
caulk. Better to be done with it and not to have it come back.

There is a hand tool that will remove the caulk without damaging the
tiles. It's basically just a plastic V-shaped blade with a handle.
You'll probably be done removing the caulk in less than 5 minutes.
Check in HD or Lowes, or your local hardware store.
Here's one:

Mix a 25% solution of liquid laundry bleach in cold water. Use a disposable
spray bottle to spray it on the moldy areas and let it sit overnight. If
the area is large, the chlorine smell will be strong so provide ventilation.
Also, wear old clothes because of the obvious effect of strong bleach on
clothing.
I've used this method numerous times in fiberglass showers and porcelain
tubs and it'll clean the caulking, or tile grout for that matter. The
chlorine in bleach will not only remove the black stain, it will kill the
mold so that it won't come back so soon. It even penetrates silicone caulk
slightly to get the mold organism that embeds itself in the surface.
Eventually, it will come back and you'll have to reapply the bleach.
Discard the spray bottle after you're done because if you try to save it for
next time, the check valve in the spray head will probably be ruined and it
won't spray.
