STAR BRITE Star Tron Tank Cleaner, 1 GAL - Removes Sludge, Varnish & Other Deposits - Concentrated Formula Works In Diesel & Gas Tanks (093600N)

This stuff seemed to do a really good job at breaking up sludge in a gas tank. Didn’t help with any rust

The package arrived quickly and was securely packaged. I have used this product before and really like it. Before using it in every tank of fui my side-by-side would not idle without going dead. I have used this in every tank, according to directions of one ounce to four gallons for the past year. Today I can let it idle forever and the motor doesn't die.

Put in fuel tanks. Pumps seam to work better

We bought an older home and come to find out the tanks had sludge in them from poor maintenance in the past. For three years now, I have been dumping this product in both tanks twice a year. I know the product works well because my filters are no longer Getting followed up with sludge.

We've had a large problem with diesel degrading into asphaltenes in generator tanks. Nothing seemed to clean the sticky tarlike deposits off the tanks and valves until I used Star Brite. Star Brite dissolves the asphaltenes from the tank into the diesel which can then be pumped out and replaced.
