How to Clean a Paint Sprayer

Paint sprayers are helpful tools that make it possible to paint a coat right over the walls. But, they can also get really dusty and sticky after prolonged use. Cleaning your paint sprayer is an easy task but can take a long time to complete if you do not have the right tools or equipment. That’s where this guide comes in handy.


First, before you use your paint sprayer for the first time, check for any warnings on its container and read the beginners’ guide to use a paint sprayer. Next, check how many gallons of paint can be used from each of your paint colors. So that you’ll know how much coverage each color has. Then, your paint sprayer needs to be cleaned.

Steps for Cleaning a Paint Sprayer

Clean your paint sprayer after each use according to an online guide or the manufacturer’s instructions. To save time, separate the parts of the paint sprayer and assemble the required tools for this task. Label each piece with tape or sticker to know how to put them back together during the subsequent use.

Step 1

If you do not have a paint sprayer with manual control, disengage the safety device that prevents the spray crosshairs from moving in another direction. To do this, depress the trigger until the plastic piece located above the trigger moves backward. Release trigger to disengage the safety device.

Step 2

First, you will need to clean the paint gun for the paint cartridge and anything clinging to it, like old paint or debris. Use a cleaning brush, clean this area from any particles or residue. 

Step 3

You will need to disassemble the paint gun from your paint sprayer and then wash it with soapy water, making sure to clean all the parts. Also, remove any residual matter in the spray gun. You can use a brush for this or your fingers to gently rub the gun back and forth against a cloth. Rinse your gun thoroughly in hot water and dry it off with a towel. 

Step 4

Once the gun is dry, you can reassemble it by snapping the gun to your paint sprayer. If you use a spray gun with a flexible hose to attach it, use pliers to adjust the hose and secure it with a clip or clamps.

Step 5

You can now spray paint onto your surface. If you need help doing this, you can get advice from an experienced person on using the paint sprayer effectively. You can also practice on something before embarking on a project that requires the help of the paint sprayer. 

Step 6

After applying the paint to your wood or steel surface, rinse off the sprayer with a hose and let it dry overnight. Never store a paint sprayer in water. Store them in a dry place away from wallpaper or other materials that could react with the product. 

Materials Used for Cleaning a Paint Sprayer

1. Water

Water can be used to clean a paint sprayer. You can use hot water or cold water if the product has been stored in the garage or basement. Spray the solution over a rag to clean your spray gun.

2. Wool Swab

Wool swabs soak up the paint residue and prevent it from being transferred to other surfaces of your house when you clean your paint sprayer. Wring out the excess water after washing the swab to prevent it from getting moldy and fungus-infested.

3. Dish Soap

You can use dish soap to clean your paint sprayer. Mix the soap with water in a bucket and soak a rag or a wool swab in the solution. Then, clean out the paint sprayer with the rag using a smooth motion. Be careful not to damage any parts by rubbing too hard or using an abrasive product like steel wool. When cleaning your paint sprayer, you should be extra gentle when handling the pump mechanism since it is made of plastic components that could get damaged easily.

4. Vinegar and Baking Soda

Shake up a few teaspoons of baking soda in a cup of vinegar and then pour it into the paint sprayer. Close the lid and let it soak overnight. You can use this solution to clean your paint sprayer thoroughly if you have not done so recently. This solution can also be used to remove grease from your hands during clean-up after using the paint sprayer.

5. Automotive Cleaners

Automotive cleaners like Purple Power are effective in cleaning most surfaces around the house. It is also a good cleaner for your paint sprayer.
