How To Clean a Paint Sprayer Gun

Many things are available to clean a paint sprayer gun from soap and water to paint sprayer cleaning solvent, to thinners. Again, what you use to clean your gun depends on what type of paint you put in it.
Cleaning your gun keeps it running in tip top shape, so that the paint you spray is smooth and consistent. Dried paint inside your gun can lead to clogging which will ruin your gun, sprayer tips, and your paint job. The last thing you want is dried bits and chunks of paint coming out onto your painting surface.

It is very important to clean your sprayer thoroughly before storing, by making sure that there is no left over paint anywhere inside your gun. Some manufacturers even suggest running anti rust and lubricants through your sprayer before storing for extended periods of time.
For example, most airless sprayers will recommend an airless sprayer storage fluid which sits inside your sprayer while it’s in storage. The fluid will lubricate and protect the valves and pump parts from corrosion and parts like gaskets and seals from drying out.
Can You Run Paint Thinner Through a Paint Sprayer?
YES! Some mediums require you to use a paint sprayer cleaning solvent like paint thinner to remove all the paint from inside your sprayer. Paint thinner is the best way to clean oil based paints and various types of lacquers and varnishes out of your paint sprayer gun. Instead of running water through your sprayer, you would run paint thinner or a paint sprayer cleaning solvent through your gun until you’ve removed all the paint.
Can You Spray Water Through a Paint Sprayer?
YES! This is actually one of the ways to clean a paint sprayer. Water is sprayed through your gun when you’ve used water based paints like latex.
