Are minikegs safe to sterilize in the oven?

Hi there and thanks for an amazing site which has really opened my eyes!!!
I just tried kegging with minikegs instead of bottling and I must say I liked the concept very much, no more endless hours filling 40+ bottles and so on... The only drawback is, the minikegs are hard to clean due to their small opening. So my question is if I could sterilize them in the oven like I did for the glass bottles. I read somewhere that aluminum melts in very high temperatures so I guess it could be done... Any thoughts?

 

If it's any kind of keg it's got to have rubber or silicone along with that aluminum. Pump some cleaner and sanitizer through it.

 

Minikegs are made like a any beer can with a lining inside. They are Steel not aluminum like a 12oz can. I would not put them in the oven!

I clean mine with PBW then store upside down in a sunny place for a while to help them dry before putting the dust cap back on and putting away for next time.

 

I read that they have a plastic lining... that's going to melt a long time before steel or aluminum. How hot would you need to set the oven?

What about a dishwasher w/ "sanitize" mode?

I've thought about getting a few as well. Any idea how much priming sugar you'd use for a mini keg?
