How To Clean The Spray Guns

At Paint for Cars, we’re dedicated to helping both DIY and professional painters get the most from their equipment. We cannot stress enough how important it is to clean your paint gun immediately after a job. Don’t worry if you don’t have a professional wash station; plenty of good cleaning products are on the market. Always wear gloves to protect your hands when cleaning spray guns.

Here’s what you need to do:

Preparation: Disconnect the air compressor and then the regulator. Empty the paint gun; paint mixed with hardener should not go back into the can.

Clean the cup: Use paper towels to wipe excess paint and moisture. Fill the gun’s cup with thinner, shake gently to coat internal surfaces, then spray the thinner into a waste container to clean internal mechanisms. Dry, then repeat 3-4 times.

For the rest:

Note: Don’t just worry about visible paint; check for any sticky reside while you work.

Disassemble the gun, removing parts like the fluid adjustment knob, the spring, and the fluid needle carefully.

Submerge removed parts in thinner, then rinse everything in thinner followed by water. Use Q-tips or an old toothbrush for nooks and crannies.

Dry the gun and its components thoroughly with paper towels and compressed air.
Reassemble the gun, lubricating threads and parts. Wipe away excess oil and ensure the gun operates smoothly.

After these steps, your paint gun should be completely clean and ready for storage, ensuring its readiness for your next project.
