I am looking for the best way to clean the inside of aluminum fuel tanks.
So far I’m thinking acetone with gravel or nuts and sloshing that around followed by a soak with ammonia.
How long to soak it is the question. I don’t want to risk damage to the tank.
Are there better ways to clean the inside of aluminum fuel tanks?
Thanks,
Drifter
If your tank is really bad inside Crystal Drano will clean it,Try 3 tablespoons & some water. With screws or nuts. Shake up and wait about 10 mins. Rinse out and check might have to repeat if bad. Then rinse with Baking Soda & water 2 times to neutralize Drano. Works very good if real dirty
OOPS! … Drano is a strong alkali (sodium hydroxide), baking soda is also an alkali (sodium bicarbonate) but much milder. Baking soda will not neutralize another alkali. To neutralize an alkali you need an acid. After a good water rinse use something like vinegar, a mild acid.
Drano will also dissolve aluminum while giving off hydrogen gas at the same time. Drano bombs ring a bell? Machinists use it for cleaning end mills and other cutting bits which have become plugged with aluminum. Just sayin.
