I have been washing my kegs and then storing them pressurized with some air from an air compressor. I thought this would be the best way to store them to keep dust and dog hair out of them. Well I opened a couple of the up to sanitize them and keg some beer and they had a very definite musty smell to them. there must have been some water left inside them after I cleaned them. So this is obviously a bad way to store kegs. I am debating to just store them dry and un-pressurized, or to store them pressurized with some StarSan in them. But I thought I would see how everyone else stores their kegs first.
