Tank varnish
Any ideas for removing varnish from a gas tank that hasn't been used in several years. I've always washed them out with fresh gasoline and even threw in some ball bearings to help knock gunk out of the tank. I'm sure there are products out there designed specifically for this. Any ideas?

steel or plastic?
steel- muratic acid- caution.

Check out the Kreem products. They have rust removal, tank etching, and liner products.

Re: Tank varnish
Acetone works better at removing tank varnish than anything else I have tried- including gasoline.
When I get a scooter that has a gummed up carb I simply remove all of the rubber seals and take the bowl off of the carb and let them soak (submerged) in acetone overnight and it removes all of the varnish.
I have done the same with fuel tanks- put enough acetone in to cover the varnish and let sit overnight.

Don't bother with commercial tank cleaners until you de-scale the tank by some mechanical means first. Trust me when I tell you that Kreme and such products really need bare metal or you will increase your problems if you try coating as is.
Good luck!

Most of my money is spent on scooterparts. The rest is just wasted.

Re: Tank varnish
for sure- Kreem works well but NOT if the tank/metal is not correctly prepped.
not cheap either. nor for the faint of heart...
