I've cleaned a gas tank with muriatic acid and have a problem:
- - flushed the tank with water
- partially filled the tank with water and put in 2 quarts of muriatic acid and completed the fill with water
- closed the tank and let set overnight
- emptied the tank and flushed with water
- partially filled the tank with water and put 2 quarts of muriatic acid and completed the fill with water
- closed the tank and let set in the sun for ~6 hours
- emptied the tank and flushed with water to clear the residue
- the tank is clean
- put in a quart of acetone and thoroughly rotated the tank to get the acetone in all parts of the tank
- emptied the tank of the acetone/water mix
- still a bit of dampness in the tank, but a strong aroma of acetone coming from the tank
- moved the tank inside to keep it out of the potential dew
- left the tank open to allow the acetone to evaporate
- ready for sealing in the morning
- two hours later the tank is bone dry with flash rust everywhere
What did I miss? My frustration meter is off the chart!
