I have a portable generator with a dirty 5 gal. gas tank. Someone left gas in it and it is nasty, So what is the best way to clean it? I was thinking some laquer thinner, or maybe some dawn dish washing soap and a lot of water? Any ideas would be helpful.

I don't know what you'll wind up doing, but I had a log splitter like that and ended up having to take the tank off, split it at the seam and paint the inside of it with JB-Weld diluted with acetone enough that I could paint a couple of coats on with a cheap bristle brush. 4 years later it is still fine, but there was no way to dissolve that stuff. I tried everything including toluol, xylol and some other solvents most people haven't even heard of. Good luck!

E85 works very well to dissolve varnished gas or diesel. I use it regularly for carb cleaning and last time was on my 47 3600 under bed tank that had a black sicky goo from forty years of sitting.

Don't want to sound stupid, but what is E85?

85% Ethanol you buy at the gas station.

It is a fuel that is 85% ethanol. You can get it at some gas stations.
Are you familiar with "flex fuel" vehicles? They are ones that can run normal gasoline or E85.

I put a shovel full of gravel into a dirty tank, strap it to the rear wheel of a tractor, and bush hog one of my pastures for a couple of hours. Jerry

I removed a heavy layer of tar from the tank on my Model A with a gallon of lacquer thinner. Then had to deal with all the rust flakes inside it that were stuck to the tar. Just about any solvent should eventually dissolve the tar-like gasoline residue.

It's a plastic tank, (something other than metal). Guess I'll try the lacquer thinner and slosh it around for a week or so.
