Just a quick question. As far a neutralizing the HF acid at 2%
that I have been applying with a shurflo, I have been doing this with a soap
base with 4% sodium hydroxide downstreamed with hot water. But I have found
that the caustic is causing rust on any nickel deficient iron on the chassis
etc. I confirmed this by looking on a corrosion information website that
said that sodium and potassium hydroxides will do this to nickel defficient
iron. To counteract this I have been applying a 10% phosphoric acid solution
after the wash but before final rinse and wax application.
What I was wondering is what do you use to neutralize the acid is it NaOH or
KOH both caustics or do you use some thing else to increase the pH of your
detergent. I was thinking maybe along the lines of sodium metasillicate or
sodium tripoly phosphate, as a substitute for the caustics any input would
be greatly appreciated.
