How to Clean a Spray Gun? Step-by-Step

It is an absolute necessity to clean the paint sprayer between coats, especially if you’re switching from one color to another. Follow the cleaning steps below to keep the gun fully functional and efficient for years.

Step 1: Preparations

Detach the regulator and the air compressor first and then disassemble all the spray gun components carefully by unscrewing them.

Step 2: Use a Paint Thinner

At this point, clean the paint cup properly with the help of paint a thinner. Scrub the inside and outside of the cup to make sure no paint remains.

Step 3: Apply the Spray Gun Cleaner

Soak all the other parts with any type of spray gun cleaner. Still, some might wonder what solvent to use HVLP spray guns.

For them, we’d suggest acetone for airless paint spray guns and lacquer for a water-based spray gun. It is because they are especially capable of dissolving any type of paint or grease from a surface.

Step 4: Start Cleaning

Now clean the parts by wiping with a cloth or a brush after you’ve soaked the individual parts with the paint gun cleaning solvent. You’ll notice the paint is coming off effortlessly. Don’t forget to scrub the hard-to-reach areas using Q-tips or an old toothbrush.

Step 5: Finish by Drying

After cleaning them, it is required that you dry the gun with paper towels. Dry them for at least half an hour before reassembling the parts together.

Final Words

Now that you know how to clean a spray gun between coats, it should be easy for you to keep the tool functioning for a long time. Don’t let the paint set inside the sprayer, or else cleaning it would be much harder.
