Thanks. I will be careful to clean it good before I re-do it and use
Clorox to kill the existing mold.

This is only the area around the shower door, where it meets the tub.
I used DAP before....the problem may very well be the way I prepped and
applied it rather than what I used.

If it is on tile, and you can use a razor blade scraper, I would do so.
Then take denatured alcohol to be sure you get all the soap scum, as
it almost assures failure if left on surface. I don't think brand
matters - DAP and GE? are the only memorable brands. I would use only
silicone for shower (non-paintable).
