A Guide to Cleaning an HVLP Sprayer
Step 1: Paint cup cleaning.
Turn the cup anti-clockwise to remove it off the nozzle. The nozzle should also be removed as you twist it away from the spray gun.
The cup is the part that contains the fluid and is likely to have some remains. It’s therefore essential to apply some paint thinner, fill it up and close the cup. After thorough shaking, spray the solution into a bucket. The thinner does most of the deep cleaning for you.
Finally, you clean up the main body of the cup by running a paper towel with some paint thinner through the cup.
Step 2: Have the Gun Body Disassembled
Now that the cup is clean, unscrew it from the HVLP spray gun to dry separately. Once this is done, disassemble the rest of the spray gun.
The gun air cup ought to be the first place to unscrew. Next, be careful as you remove the needle, which is very delicate, and loaded with springs; thus, you have to be very careful.
The separate the gun completely, open up the inner parts, and set them aside.
Step 3: Deep the Parts in a Paint Thinner

Break up any paint residue in the parts as you dunk the outer air cup, inner air cup, and the main body in the solution. For proper soaking, allow at least 30 minutes.
Step 4: Dry out the spray gun
It’s now time to get the parts from the painting solution. Wipe them with a bristle cleaning brush. You can use toothpicks as an alternative. Since the parts spent ample time in the thinner, wiping them will take a shorter period to achieve effectiveness.
A toothpick can be used should you notice any buildup around the ridges. Since you didn’t soak the needle and the spring with other parts, apply the thinner to a piece of cotton and wipe the spring and the fluid needle.
Step 5: Reassembly
Once every part is clean and dry, it’s time to get them back together. You start by putting the needle and spring in their positions. Screw on the inner cap then the outer. Wrap up the procedure by putting back the gun body and screw up the cap.
