Old crusty gas in the bottom of a steel OMC tank. Anyone know of a good way to clean it out. Its gummy and kind of soft. Tried to leave a mix of fresh gas and oil mix in it over the winter and that seemed to soften it a bit but still stuck in a lot of it. Tank is in good shape other than that as in no rust inside or out. Is there something that would dissolve it? Thinking a can of Sea Foam or maybe some of that stuff used to soak carb in?

Place some pea gravel in it and shake vigorously. That will break up the deposits in it.

I have had some luck with vinegar and water. Dump a jug of vinegar in and shake around or turn the tank periodically. Fill rest with water and let it sit. Take it to a carwash one town over at night and blast the heck out of it. Lol. Lacquer thinner eats the stuff good but will also take the paint off the outside. Last one I did was vinegar and carwash, then I put an inline fuel filter right off the tank.

I like a handful of 1/4" nuts.

Acetone to clean out a tank, gravel too sounds good! ADD a Racor fuel-water separator for good measure, cheap insurance!

That what I have done before with a motorcycle tank. Worked great.

Thanks for the ideas! Ended up using the pressure washer. Took the fuelcap off one end of the old metal tank and gauge off other end and it worked great.
