Have five gas tanks and keys for four of them, I have not done an extensive examination on any of them but some have liquid in them. I will probably repair side dent and POR-15 one of them for the bike I hope to rebuild. Question, how best to clean and preserve the others until they are needed? BDC
dry them out
:) Put a quart of 2-stroke oil in an empty tank, give it a good swirl around and empty out... 8)
