Wear protective gloves before starting because the paint thinner or the cleaning solvent you will use in the cleaning process can be damaging to your skin. The process also entails disassembling all the parts for thorough cleaning; hence, you should familiarize yourself with all the components of a paint gun sprayer

  • Start by detaching the air compressor and then the air regulator.
  • Drain all the paint from the gun. If the paint in the gun had been catalyzed, do not mix it with the original paint in the can to avoid hardening it as well. Otherwise, if you were applying a base coat material, you can return to its original can. Use paper towels to wipe any leftover liquid in the container for easy cleaning.
  • Dissolve any residue left in the gun throat by pouring a small amount of thinner into the cup. Close the lid and shake gently and thoroughly. Then flush out the used clean by squeezing the trigger like you would when spraying. Repeat steps 1 and 2 until you are satisfied with the results.
  • When you remove the adjustment knob, the spring will be exposed, squeeze the trigger and pull the fluid needle. This should be done with care to avoid bending the needle. Turn the air cap is an anticlockwise direction to remove it. After you have dismantled all the parts of the sprayer gun, wipe them with a waste thinner.

You can also blow compressed air into holes in the parts to get rid of any liquids trapped in there. Leave the components for a few minutes in the open air to dry completely.
  • Then lubricate the parts using O-ring lubricant in preparation for reassembling. Lubricating gives you an easy time fitting the pieces together and also prevents scratching against each other which can cause damage. Wipe any lubricant on the gun after you are done with the assembling.
  • Then clear the working area and store the remaining cleaning solvent properly. With these simple steps, you have cleaned your paint sprayer gun.
