6 months ago i scraped off the old caulk in the bathroom shower because of mildew, and use mildew resistant caulk from Home Depot.

i waited 48 hrs before using the shower.

mildew is again forming.

Recommendations on what type of caulk to use?

Well silicone is generally the best although a bit harder to remove when you need to. Still, in 6 months is there standing water on this caulk?

The thing about caulk is that it's intended to come in contact with some moisture, but if there's too much moisture--it's too damp for too long a period of time--it's likely to contract something.

Yeah, if it's in continuous contact you probably want a different surface material - like plastic - rather than tile/ceramic and caulk/grout taking the brunt of it.

Use GE Silicone II if it's in the tub or shower, or if it doesn't need to be painted.
Use DAP DYNAFLEX 230 if it has to be painted.

Speaking of caulk, would silicone caulk work ok for gutters? I have a few leaks in mine that I should probably fix.
Silicone caulk would work for gutters, but I would try solder before pulling out a tube of silicone/sekaflex/polyurethane.

No such thing. I've bought the really expensive GE silicon III for like $8 and it still mildews overtime. Cleanliness bra. Once a week hit shower with scrubbing bubbles.

no such thing.
depending on bath design and room conditions the wet time will lead to mildew unless things are fastidiously dried each time. just be resigned to doing this chore from time to time.
silicon lasts a little longer but is a big pain to replace and harder to deal with during application, either chemical removal or no regular caulk will stick in the area its been. so i'd suggest an advanced regular caulk. walmart sells a pretty good plastic caulk remover scraper thing. makes most of it pretty quick so you can use a lot of force without worrying about scratching. use a razor scraper to get the rest. after a while you can do it in no time.

Squeegee after showering will remove the majority of water/moisture and minimize any mildew growth.

Have tried multiply type of chalking for my shower and find that they will all mildrew over time.

The best solution that I have found is to try the shower out after you shower.
