Fill the gas tank with a couple inches of water to clean out varnish. Pour a cup of muriatic acid into the tank. Move the tank around for a few minutes so the solution covers the inside completely. Pour three or four cups of lime into a bucket.Pour a gallon of water into the bucket and stir it with a long stick.ove the tank around a few minutes. Let the gas tank sit overnight to clean varnish out. Repeat Step #5 to neutralize and dispose of the muriatic acid. Spray the inside of the tank out thoroughly with a garden hose. Allow it to air dry before you use it again. Otherwise you'll have water mixed in with the gas.
