Why Should Spray Gun Never Be Cleaned By Spraying Solvent?

Spray guns are widely used in various industries for painting and coating purposes. However, the efficient and effective use of spray guns demands proper maintenance and cleaning after every use. Cleaning the spray gun is crucial to avoid clogging, irregular spray patterns, and other defects that can affect the quality of the final product. Many people use solvents to clean their spray guns, but this method is not recommended. In this article, we will discuss why spray gun should never be cleaned by spraying solvent.

The Dangers of Solvent Cleaning

Solvent cleaning involves spraying a cleaning solvent through the spray gun to remove the leftover paint or coating. While this method may seem convenient, it is not without its risks. Solvents are highly flammable and can pose a significant fire hazard. Spraying solvents can lead to the accumulation of vapors, which can ignite with even a small spark.

Moreover, solvents can cause health hazards as well. The fumes emitted by solvents can cause respiratory problems, dizziness, and headaches. Long-term exposure to solvents can also lead to more severe health issues such as liver and kidney damage, nervous system disorders, and even cancer.

The Risk of Contamination

Spraying solvents to clean a spray gun can also lead to contamination. Solvents can remain in the gun’s nozzle, trigger, and other parts, leading to cross-contamination between different paint or coating types, resulting in compromised quality. The residual solvent can also mix with the next paint or coating, leading to chemical reactions that can cause the spray gun to clog or malfunction.

The Best Way to Clean Your Spray Gun

So, what is the best way to clean your spray gun? The recommended method is to use a dedicated cleaning kit designed for spray guns. These kits come with specific brushes, cleaning fluids, and containers that enable you to clean the gun thoroughly without any risk of contamination or health hazards. The dedicated cleaning kit also ensures that you clean every part of the spray gun, including the nozzle, trigger, and other components, to ensure optimal performance.

Conclusion

In conclusion, spraying solvent to clean your spray gun is not recommended. Solvents pose fire and health hazards, can lead to contamination, and compromise the quality of the final product. Using a dedicated cleaning kit designed for spray guns is the safest and most effective way to clean your spray gun. Proper maintenance and cleaning of your spray gun can extend its lifespan, improve its performance, and enhance the quality of the final product.

FAQs – Why Should Spray Gun Never Be Cleaned By Spraying Solvent?

1. Why is it harmful to clean a spray gun by spraying solvent?

When you clean a spray gun by spraying solvent, it can create a mist that can be inhaled, leading to respiratory problems. Moreover, the solvent can damage the spray gun’s components, such as the gaskets and seals, which can lead to leaks and affect the performance of your spray gun.

2. Can’t I use a high-pressure spray gun cleaner to clean my spray gun?

No, using a high-pressure spray gun cleaner can damage the spray gun’s delicate parts. The high pressure can also force solvent into the air cap and fluid passages, leading to clogs and blockages. It’s best to use low-pressure cleaning methods that are specifically designed for cleaning spray guns.

3. What is the best way to clean a spray gun?

The best way to clean a spray gun is to use a dedicated cleaning kit that includes brushes, swabs, and low-pressure solvent. First, disassemble the spray gun and soak the parts in the solvent for a few minutes. Then, using the brushes and swabs, gently clean the parts, making sure to remove any dried paint or debris. Finally, rinse the parts with water and allow them to air dry.
