Types of Solvents for Cleaning HVLP Spray Guns

There are a variety of solvents that can be used to clean HVLP spray guns. The type of solvent you choose will depend on the type of paint you used and the material of your spray gun.

Mineral spirits are a good choice for cleaning HVLP spray guns that have been used with oil-based paints. Mineral spirits are a petroleum distillate that is non-flammable and evaporates quickly. They are also relatively inexpensive.

Lacquer thinner is a good choice for cleaning HVLP spray guns that have been used with lacquer-based paints. Lacquer thinner is a strong solvent that can dissolve both oil-based and lacquer-based paints. However, lacquer thinner is flammable and can be harmful if inhaled or ingested.

Acetone is a good choice for cleaning HVLP spray guns that have been used with acrylic paints. Acetone is a strong solvent that can dissolve both oil-based and acrylic paints. However, acetone is flammable and can be harmful if inhaled or ingested.

Water-based solvents are a good choice for cleaning HVLP spray guns that have been used with water-based paints. Water-based solvents are non-flammable and relatively safe to use. However, they may not be as effective as other solvents at removing oil-based paints.

Specialty solvents are available for cleaning HVLP spray guns that have been used with specific types of paints. For example, there are specialty solvents for cleaning HVLP spray guns that have been used with epoxies, urethanes, and other specialty paints.

When choosing a solvent for cleaning your HVLP spray gun, it is important to consider the following factors:

  • The type of paint you used. If you used an oil-based paint, you will need to use a solvent that is compatible with oil-based paints. If you used a lacquer-based paint, you will need to use a solvent that is compatible with lacquer-based paints.
  • The material of your spray gun. Some solvents can damage the plastic parts of a spray gun. If your spray gun has plastic parts, you will need to use a solvent that is safe for plastic.
