I have re-caulked my shower stall recently (and once a few years ago).
Both times, within a few weeks the caulk has started getting moldy. I
used the best stuff I could find at Home Depot. Is there a brand out
there that is considered the best and will keep from molding? This past
time I even used one of those "after shower" sprays to try to help.
the only thing that works for me is GE silicone I bathtub caulk. Dap latex,
Dap Silicone and GE Silicone II all mildewed on me within a year. I'm going
a year with the Silicone I and no signs of mildew yet. I get the feeling it
has to do with "paintable" property. GE silicone I is a slick surface and is
nonpaintable. THe other 3 I mentioned all have a matt finish and are
paintable. Maybe the paintable stuff collects dirt which the mildew feeds on
(I'm guessing). Available at lowes.
THe problem I have is that with 3 people in the house, taking showers in the
morning, afternoon and evening, the stuff never dried out.
I also had to use a silicone sealer on the grout. I'm guessing again , that
enough water was getting behind the caulk in the grout that it never dried
There is no one "best" caulk. It sounds like you used a very good
caulk, but used it in the wrong place. You may need to replace it, but this
time use a good caulk that indicates it is designed for bath and kitchen
use. They have mold protection built in.
The "after shower" spray is not going to help much if any. They are
there to keep the soap scum from sticking and to allow the water to sheet
off rather than dry with spots.
You know what? I just assumed... checked mine and you are right. They
are worthless! I think I'll add bleach to what I have to make it do
what I want. I don't think it would take much bleach to defend against

I use a squeegee to get the water off the shower walls after a shower.
Target used to have nice big ones for shower use. That is all I used to do
and still got some mildew growth even with a big vent fan. So now I do that
AND one of those everyday shower sprays and the combination is close to
perfect preventing mildew.
Actually my last step is after I dry myself with a towel a drag the towel
around the edge of the shower wall and floor to get the caulk pretty dry.
But I the other poster said, if the walls are squeegied things will dry up
pretty fast if ventilation is good.
