Matti,
I could be anal at cleanliness(hence the name), but once ive blown a keg(just did), I pull it all apart, rinse with hot water, fill keg with hot water and a tsp of pbw and leave sit overnight with all the bits dropped in, I then rinse with hot water, turn upside down and sit on a towel with all the seals, poppets, posts to drip dry until needed..(Got 3/4 empty ATM)
When it comes to filling, all the bits go into sanitising solution and some in the keg, I then pull bit by bit out, greasing every seal/poppet/prv and attach to keg. I then give it all a good shake and run the Starsan out, then fill, seal, purge and gas..
Personally, id rather break it down everytime just to keep everything nice and clean and prolong the life a little, ive seen some things on here that people havnt paid attention too and it usually ends up messy.. I also lost alot of gas due to dodgy un-lubed seals..
