I want to clean the inside of the gas tank of my 45 Chevy. There is almost no rust at all but there is varnishy sludge in the bottom, a residue of old gas.
So I'll need to use some solvent to dissolve the sludge and I was wondering if there is anything better than fresh gas to use to do this with?
I'm interested in hearing any and all tips for getting the varnish out of the tank!
