How to Clean a Paint Sprayer?

After gathering all the items, you will have to follow some simple steps to clean out the paint sprayer.

Step 1: Pressure Release

Before getting to the cleaning part, you need to take care of certain things, like the pressure of the spray gun is necessary to be at the lowest settings. All the pent-up pressure is to be released to carry out the cleaning process more smoothly. Engage with the trigger of the gun sprayer. Keep a waste bucket near you and dip the sprayer into it. Release all the pressure by reversing the spray gun. Then turn the valve in to its prime position. This will avoid the sudden splashing of paint on your body.

Step 2: Flush the Residues

The next step to follow is eliminating any paint residues. For that, we have to open the tip of the paint gun sprayer and empty all the paint. Put the sprayer into the waste bucket. Then, change the command from prime to spray. You can also increase the pressure while continuing to flush out the paint. Slowly remove it from the bucket if you notice that the flow of the paint is fading. Now check the nozzle to see any remaining paint particles.

Step 3: Pump Cleaning

Now comes the cleaning of the pump. You have to put the sprayer into the flushing bucket to do this. Turn it on and let the flushing fluids rush. Watch closely until it’s crystal clear. Then steadily release the pressure trigger off your gun. Turn it from prime valve to prime position. Allow the fluids out of the pump. Again, if the fluids do not have any color in, it means your sprayer is almost clean.

Step 4: Gun Cleaning

Now that your pump is paint-free, your next step is to clean the gun itself. For this purpose, turn the prime valve option to the spray option. It is particularly important to switch between prime and spray and vice-versa throughout the cleaning process. It is an integral part of cleaning the sprayer. Now, after you turn it into the spray position, place it above the flushing bucket to clear up the hose.

No paint coming out means you have done a pretty good job up till now. If not, you may have to repeat some processes back to back. The next thing to move on to is engaging with the trigger lock. Like in the very first step, you should set the control knob into the lowest settings. Then turn off all the power flow. This will leave us with our last step to follow, i.e., to remove all the filters from your sprayer.

Step 5: Filter and Tips

We have finally reached the end step towards cleaning the paint sprayer. It includes removing all the filters and tip guard attached to it with the help of the flushing fluid. This is when you can use the soft bristles you equipped yourself with prior to starting the cleaning process. Then flush your sprayer with enough water. Finally, dip a cloth in water or mineral spirit to wipe the sprayer. You can use mineral spirits if you want. It will prevent the paint sprayer from corrosion in the future.
