 After knowing some basic tips of cleaning a spray gun, we shall now look up to the steps that you should follow to get everything right. 

Step#1: Prepare the Sprayer

Most importantly, you got to ready the sprayer for cleaning. You have to make sure that the sprayer’s pressure is set to the lowest level possible, and the power is turned off. After that, carefully remove the filter and tip components and turn down the prime valve into the open position.

You can activate the spray gun to get the insurance that the maximum amount of pressure has been relieved.

Step#2: Clean the Smaller Parts

Use any washing fluid, consisting of water and paint thinner, to clean the small parts like tips and filter pieces.

This step is a little boring, but it should not be a challenge.

Step#3: Remove the Siphon Tube

After cleaning the smaller parts of the spray gun, you have to remove the siphon tube very carefully and put that in a flushing solution.

The flushing solution that would be used will depend on the kind of paint that was used. If your paint is water-based, then you would need a water-based solution, while in the case of oil paints, your flushing solution would be mineral spirits.

Step 4: Flush it Out. 

When your Siphon tube is out and in a flushing solution, it is time to use your sprayer gun to flush out the entire system.

Now you have to activate the trigger mechanism by again turning on the power, and after a few minutes, you will see your flushing fluid coming out of the spray gun. Let that flushing fluid flow until you witness that liquid comes out clear. Give that fluid some minutes so that it can circulate well in the prime valve as well.

Finally, swab down the exterior portions of your spray gun with any small rag that has already been soaked in mineral spirits or water. Be sure to discard the waste from this process positively, as keeping this waste longer can be very harmful.

Once it has been done, you can begin the reassembling of the sprayer to use it again.

Note that, in case you have a sprayer that has garden hose valves, so you can easily hook your sprayer right up to that garden hose and flush it out in even less time.
