Thread: How to: Clean gas tank?

I've got the tank sealed, so it won't evaporate.

The MEK is sure enough pricey, I'll give you that, but it's sure enough cutting through the crud.

I gotta find someone with tiny hands and long arms, to reach in the hole and feed chain past the baffle on the one side. Then with a section of chain in each side, and a the tank well grounded, I'll slosh it around with the chains to help churn up and dissolve the goo. I'll do it early morning while it's nice and cool, the MEK will be slightly less volatile that way. I'm thinking to purge the air with argon/ CO2 as well. Explosions are bad.

I'd like the idea of pea gravel, but I can't imagine how I would ever get it all out. The chains will be easy, just hook them with a clothes hanger and gently pull.
