I have a Neo steam shower and the caulking is beginning to 'separate' and certainly mold/mildew. No problem cleaning it, as I either use Soft Scrub or sometimes bleach and a brush and that works for a few days.

The question is, now do I remove the old caulk and what do I replace it with? The old caulk is not very brittle and is certianly not pliable - and when I take a screw driver to it it breaks away in tiny pieces and is very hard - like automobile bondo.

The replace question is relative to tolerating the heat that is generated when the steam shower is used.

Any suggestions appreciated!

Thanks,

Brian
