Spray guns come in a wide variety of designs, each with its own specific cleaning needs. As a general rule, however, most hvlp spray guns can be cleaned with a mild solvent such as alcohol or mineral spirits. More important than the type of solvent you use is the method by which you apply it.
When cleaning your hvlp spray gun, be sure to first remove any paint or other debris from the exterior of the gun. Next, disassemble the gun as much as possible, being careful to not lose any small parts. Once the gun is disassembled, soak all of the parts in the solvent for at least 30 minutes.
After soaking, use a soft brush to scrub away any remaining paint or debris. Be sure to pay special attention to the nozzle, as this is often the most difficult part of the gun to clean. Once you are satisfied that all of the parts are clean, reassemble the gun and test it out with some water to make sure it is working properly.
If your hvlp spray gun is particularly dirty, you may need to repeat the soaking and scrubbing process a few times before the gun is completely clean. However, with patience and a little elbow grease, you should be able to get your hvlp spray gun clean and working like new again.
