An airless paint sprayer is a great option for you to use. It will help get the painting done in no time. However, once you are done using the paint sprayer, it is time to clean it out so it is ready to use again. Failure to do this will mean that paint will get stuck inside, and the paint sprayer will stop working.
With the right steps, you can learn how to clean an airless paint sprayer. Let's take a closer look at how you can make your airless paint sprayer clean.
Before you get started with your airless paint sprayer, make sure that you are staying safe and do not get harmed by the solvent or other chemicals that are used during this time. Some of the precautions that you should take before you try to fully clean an airless paint sprayer include:
Steps To Clean An Airless Paint Sprayer
It is now time to clean out the airless paint sprayer to get all the paint out. Some of the steps that you need to use to help with this include:
1. Set Up Buckets
You will need to set up a few buckets to make sure they have the right solutions in place. You will need to pick a paint sprayer cleaner or a solvent that works for the type of paint inside of your sprayer.
Keep one bucket filled with water and soap, one with the chosen solvent, and one that is empty so that you can pour the dirty liquid cleaner into that later.
2. Clean Out The Paint
You will need to place the suction hose of the paint sprayer into an empty bucket. Aim it at the empty bucket. Push the prime mode and the spray mode in order to get all of the remaining material out. Add more water to the paint container and flush it through too. Continue pushing it in and out until the liquid comes out clean.
3. Cleaning The Filters
The filters are important to your work in this paint sprayer. There will be two to three filters on these sprayers. Unhook these from the air gun and add them into a bucket of soapy water or a solvent mixture. Never place the entire gun inside.
Let the filters sit there for five to ten minutes. After that time, remove them from the solvent and scrub with a brush to remove the paint. You can add them back into the solvent for longer if the paint is really stuck in the filter.
4. Clean The Nozzles
This is probably one of the most tedious parts of the process. You may want to use an old toothbrush, pipe cleaners, and a needle to get all the paint out. Place into the solvent to make sure that it has a way to release the paint. Then scrub with the toothbrush until the paint is gone.
Run more water and solvent through to help rinse out the paint when necessary. Look through the nozzle and see if you notice a small amount of light showing through. It is clean when that is done.
When these are all cleaned off, give the spray gun a good scrub on the outside and then wipe everything dry. Then, use the user manual to help put it all back together again.

Airless Paint Sprayer Cleaning FAQs
Can I leave paint in an airless sprayer overnight?
It is best to never leave paint in the airless paint sprayer for more than a few hours. If you do, this will clog up the machine and make a bigger mess than you want to deal with. So unless the second coat will be done soon, it is best just to clean out the paint sprayer right away.
What is the correct way to store an airless paint sprayer after use?
If you plan to use the airless paint sprayer in a few days, you can leave the tubes in the paint can and then cover everything with a bit of plastic wrap. Release the pressure out of the sprayer but leave the gun and hose in some water to keep it from drying out. Put a bag over it to prevent any leaking.
If you plan to store this for up to three months, you need to get all of the water out of the machine. Make sure that the sprayer is going to be cleaned out of paint, and you give it time to dry out. You can keep items hooked up if you know you will use it again soon.
For long-term storage, try to take everything off and clean it well. Add a bit of mineral spirits to make sure nothing is left behind. Turn off the pump, take all the parts off, and store them together. It is a good idea to wrap it up in some plastic wrap to keep it safe.
