I made a nice kegerator from a freezer using the collar method, and I have lots of moistures issues. I've tried all kinds of moisture removers, including the one with the beads that you plug in, and I still get lots of condensation. It's making it rust quite a bit. A few years ago I scraped all the paint around the rust points, sanded, and repainted with the proper paint; the rust came back. So annoying Suggestions? Thanks in advance from a new BA user. -=Toddlikesb33r=-
I live on the coast where the humidity is oppressive . . . corrosion control is a large part of my life. There is no "magic" answer to make that moisture go away. On the inside there should be little to no metal surfaces, so no rust issues but mold/mildew is the problem. The beads were marginal for me. I haven't tried DampRid, others say it helps some. Try to minimize the opening, that helps a bit . . . other than that it's rags/shop-vac to keep the inside dry. I also dropped the lid's insulation to expose the metal underside . . . this was even more discouraging as there was quite a bit of rust there. My exterior started to rust after only a year from applying primer/oil-based paint. Other than isolating the unit in a humidity controlled room I know of no other work around. So for me it's sandpaper/ospho/primer/paint to keep it intact. Rustoleum does make a "rust-colored" oil-based paint that will effectively camouflage the problem (it will continue to rust but no one will know it . . . until you-know-what).
I'm confused, where exactly are you having moisture issues? If it's related to condensation you can fix it, if it's due to atmospheric humidity you are sol my friend. Although I will say just painting over rust will not fix your problem. You would have to use an acid wash on the metal to completely remove the rust before repainting but other than either car paint or powder coating I don't think any other paint would be durable enough to last. Maybe a thick clear coat would work but the key really is getting all the rust out before you put anything back on or the remaining rust underneath the surface will just lift anything off of it eventually.
I think @PortLargo is right, just something I have to deal with. I believe it's condensation from atmospheric humidity. I live in Seattle, and while it's not as humid as Boston, it is a coastal city. I try not to open it too much, somedays more than others for sure. On cold days I will sometimes just leave the lid open and let it dry out over night. It's not best case but the kegerator is in the basement which is fairly cool. When I repainted the rust spots I did scrape the heck out of it first and used appliance paint. I did not however try acid wash, so that's something to think about when\if I do it again. Thanks @beerdumper.
You may also want to check your seals - put a flashlight inside and turn off the room lights. Any small gaps will contribute to moisture as room air can get in.
After my last keg, I started to notice water drip out of my keg onto the floor. I didn't think nothing of it, after i finished the keg I looked inside to clean the lines and the back plate was dripping water and all my water bottles were soaked. I didn't have this problem before so i am not sure what could be wrong with it. The seals look good and it is a Sanyo 1206S.
Did you do the flashlight test as mentioned above, or did you just look at the seals? Looking good and working properly are different things. Moisture is a sign of warmer air getting into the unit and causing condensation.
I did do the flash light test, but I'll take a close at the seals and try the flash light test again. The Tower wasn't sweating at all.
