So I just got a keg for free from a friend and it had been neglected for sometime so it is kind of crody on the outside and there was some wine in it that was quite old. What should I do to get ready to put a brew in it. Also I have no experience in kegging maintance at all so anything will help.
A hot soak with PBW will help. Disassemble all the posts, poppets, and dip tubes. Make sure the o-rings are replaced if you’re concerned that the previous use will impart flavor to your beers. Sanitize with StarSan.
You might want to get the long skinny brush that can be used in the dip tube. Same as a .22 caliber rifle cleaning brush I have been told.
Martin has good advice for the rest of the procedure.
I would suggest getting some keg lube and putting it on the new gaskets. It helps keep them from getting dry and allows for a nice seal.
You said you had no experience in keg maintenance. Do you have experience kegging? I ask because I just got started kegging and was surprised at the associated expenses - Co2 tank and regulator, faucets, etc. There was a back issue of BYO that addressed getting started and I thought was pretty good. Pressure testing your cleaned and refurbished keg is a good idea before you trust your brew to it.
good advice above for the functional aspects. just for appearance, if you want to get rid of the “crody” look; Bar Keepers Friend (it’s non-abrasive) and a green scrubby pad work wonders.
I have also used my oscilating sander with 400 grit sand paper followed by 1000 grit automotive paint sandpaper. They sparkle and shine now!
I also agree with Martin and Jeff…
