Gas tanks

Anyone have a way to clean out gum and rust from old gas tanks beside steaming them out ?

 

This might help.

try using toilet bowl cleaner. I used it a couple of times and it works fine. let it set for a couple of hours then rinse with hot water and spray with wd 40.
add a little water and slosh it around a few time.

denatured alcohol sloshed around will cut the gum. Let it work a day are so.

 

Drop a small chain in there with it when you start sloshing... that'll help knock the big chunks loose!

 

Thanks guys you all helped on this one, Hank

 

Yeah, and the sparks it creates in there will add that little extra bit of suspense that makes life so exciting.

 

I substitute small rocks for the chain.

 

First clean the petroleum products out with a soap or alcohol, I use Castrol Super clean or Joy Dish soap, then clean the rust with muriatic acid, wear gloves and a respirator, rinse with water and then alcohol to remove the water.
