Empty the Container

Make sure to unplug your sprayer before you start to clean your sprayer. Then unlock and twist the sprayer head off of the motor part.

Then start emptying the paint container. This step may seem obvious, but there is no point in wasting paint or pouring it down the drain. Plus, it’s not good for the environment or your drains.

So, pour the excess paint from your sprayer’s container, back into the paint container or another container with a lid.

If the size of the container is just right, you can balance the sprayer’s container tilted upside down so most of the paint can run out and into the other container.

Rinse the Container and Suction Tube

Next, rinse out the container and the suction tube. If you used water based paint, you can use warm soapy water for this, but if you used oil based paint, you’ll need to use mineral spirits for all of this process.

If you aren’t sure, read the label on your paint container to see what it says about cleaning up the paint.

The goal here is to remove most of the paint from inside the container, so you can have some clean water or mineral spirits to run through the paint sprayer in the next step.

If you have a bunch of paint left in your container when you move onto the next step, then the inside parts of your sprayer won’t really get cleaned out.

Spray Cleaning Solution Through the Sprayer

Once the container and suction tube is all cleaned, fill the sprayer’s container with some of your cleaning solution. So if you used water based paint, put some warm water with some dish soap into the container.

If you used oil based paint, put some mineral spirits into the container.

Put the suction tube back into the sprayer, and screw the container back on. Put the sprayer head back onto the motor.

Plug your sprayer back in, and then spray the cleaner through the sprayer for a few seconds, until the liquid comes out clean. I like to spray into a 5 gallon bucket, or into a rag to contain the spray.

This step cleans the inside of the sprayer, where you can’t get any other way.

Disassemble the Sprayer

Then you can unplug the sprayer, remove the motor from the head of the sprayer, unscrew the container, and pour out the cleaner.

Then, disassemble the sprayer’s nozzle. For the detail finish nozzle, you can unscrew it and then a few small pieces fall off.

Don’t let any piece fall down your drain! But use a small brush to clean inside of the tip of the sprayer and remove any paint from the other 2 pieces. I also like to do a final rinse on the container and the nozzle.

If there is overspray on the outside of the container, I use a wet rag to rub off the paint.

Let Dry Completely

Last but not least, let all of the parts dry completely before you put it all back together. If you put it back together wet and start spraying again, then the sprayer will start dripping while you spray… Which ruins the finish.

You can, of course, try to speed up the drying process by drying everything with a rag.

That’s all there is to it! Honestly, the Wagner paint sprayers are the easiest of all of the paint sprayers to clean! That’s one of the biggest reasons I keep going back to them. But they also spray very well, especially these FLEXiO sprayers.

Here is our list of the best Wagner paint sprayers for furniture.

How often should I clean my Wagner FLEXiO sprayer?

You should clean your Wagner FLEXiO sprayer after every use. This will help keep it in good condition and make sure that it is always performing at its best. If you don’t clean it after each use, paint can start to accumulate and clog the nozzle, hindering the spray quality.

It’s also important to remember that you should always use the type of cleaning solution recommended on the paint’s label, as different types of paints require different types of solution.

Can I use regular soap and water to clean my sprayer?

Yes, if you are using water based paint you can use regular soap and water to clean your Wagner FLEXiO sprayer. However, if you are using an oil-based paint then you will need to use mineral spirits instead of soap and water.

Typically, the back of the paint container will tell you what to use when cleaning up the paint. If not, you can usually find the information on their website.

Note: Shellac based products should not be used in these sprayers because shellac’s flash point is so low.

Is it necessary to disassemble the sprayer to clean it?

Yes, it is necessary to disassemble the sprayer after each use in order to properly clean it. This will make sure that all of the internal components are free from any paint residue.

The process should only take a few minutes and can be easily done following the steps outlined in this guide.

What’s the best way to dry all the parts after cleaning?

The best way to dry all of the parts after cleaning is to let them air dry. You can try to speed up this process by wiping down the parts with a rag, but you should always make sure that they are completely dry before putting them back together and using the sprayer again.

This will help prevent mold or mildew from forming inside, and it will help your sprayer spray correctly.

Are there any special cleaning products or tools I should use?

No, you don’t need any special cleaning products or tools to clean your Wagner FLEXiO sprayer. All that is needed is a warm water and soap solution (for water based paints) or mineral spirits (for oil based paints) and an old rag.

If you want to make sure you have gotten all of the paint from inside the nozzle, a small brush will do the trick and help make sure that your paint sprayer doesn’t get clogged.

    I live in a County area and have a Septic tank instead of city sewage. What steps should those of us on septic systems use? I can’t think this would work with a septic system. Thanks for answering for me!
