Emptying Paint Sprayer Container

Start by unplugging your Wagner FLEXiO 3500 paint sprayer. Of course, it’s important to make sure the sprayer’s not plugged in during the cleaning process for safety reasons.

Next, twist off the sprayer head from the motor part and begin emptying out any remaining paint from the container. Don’t let that leftover paint go to waste!

Pouring paint down the drain isn’t good for the environment or your pipes, so try to transfer it back into its original container or any other container with a secure lid.

You can also drain the paint container by balancing it upside down on top of another container. This will allow most of the paint to run out, making it easier and quicker to clean. Just make sure you have a steady hand and don’t spill any excess paint on your work area!

Rinsing Paint Sprayer Container And Suction Tube

Now it’s time to give that container and suction tube a good rinse. If you used water based paint, just warm soapy water will do the trick. But if you painted with oil based paint, you’ll need some mineral spirits on hand for this step.

We want to get rid of as much leftover paint as possible before moving on. So give those parts a good rinse, using warm soapy water or mineral spirits, depending on the type of paint for furniture you used.

Spraying Cleaning Solution Through Paint Sprayer

After rinsing out the paint sprayer, fill the container with the same cleaning solution (warm soapy water for water based paint or mineral spirits for oil based paint), place the suction tube back in, and screw on the container. Then attach the sprayer head back onto the motor.

Plug and turn your Wagner FLEXiO 3500 back on and spray the cleaning solution through for a few seconds. You’ll want to do this into a bucket or onto a rag to catch the liquid. This helps clean the inside of the sprayer where you can’t reach with regular cleaning.

You’ll know when the sprayer is clean as the liquid will come out clear. So keep spraying until it’s no longer colored with paint or any residue.

Cleaning Inside Paint Sprayer Tip

Next, take apart your paint sprayer for a deeper clean. Unplug the sprayer and remove the motor from the head. Then unscrew the container and pour out any remaining cleaning solution.

Don’t forget to disassemble the sprayer’s nozzle by unscrewing it and removing any small pieces. Be careful not to let them fall down your drain!

What we mean by deeper clean is cleaning the inside of the tip of the sprayer and removing any paint from the other pieces. Get a small brush to help you with this step.

After doing so, do a final rinse on the container and nozzle. For any overspray you see on the outside of the container, just use a wet rag to wipe or rub it off.

Drying Paint Sprayer Completely

After all the cleansing and rinsing, the final step is to let your Wagner FLEXiO 3500 paint sprayer dry completely. Putting the parts back together too soon can lead to dripping and a ruined finish on your project.

If you’re in a rush, you can wipe the parts down with a clean rag to dry them quicker, but you need to make sure they are completely dry before assembling and using the sprayer again. You don’t want any mold or mildew to form inside, which can affect the spray quality and lifespan of your paint sprayer.

It would be best to let them air dry completely – this way, you can get rid of any leftover moisture or water completely. It might take a bit longer, but if you don’t have to start another project right away, it’s worth waiting.
