acetone to clean spray gun

Acetone, are there any advantages or disadvantages to use it to clean a spray gun? Is it better or worse than lacquer thinner?

Depends on what you've shot thru the gun. I use laquer thinner, but don't leave it in the gun for a long time, it can damage the o rings and seals.

When in doubt you can use the thinner or reducer of the paint you sprayed. Lacquer thinner will always work.

 

S/P told me to use acetone to clean my spray gun if I sprayed slick sand....I think it cleans better than lac thinner.

 

I think that some lacquer thinners contain acetone; which would make it evaporate faster. I use acetone, but it does evaporate a lot faster than lacquer thinner.

 

There is not a set formula for lacquer thinner, so it's not all the same. However, lacquer thinner, especially if it contains MEK, is a more aggressive solvent than acetone alone.
