Supplies Used:

Step 1: Rinse Out the Container

So, first I dump out any remaining paint from the sprayer’s container and put it back into the original paint container.

Then I rinse out the container, the suction tube, and the little filter at the end of the suction tube.

Step 2: Spray Cleaning Agent Through It

When it’s all rinsed out, I fill it with hot soapy water (for water-based products).

And then I spray the hot soapy water out of it and into a 5-gallon bucket.

Spraying hot soapy water gets all the paint out from the inside of the sprayer.

Step 3: Spray Water Through It

Then I spray clean water through the paint sprayer to rinse out the soapy water.

Step 4: Disassemble the Tip and Needle Areas

Then I remove the container and start taking the sprayer apart.

I unscrew the knob on the back that holds in the needle.

And then I unscrew and remove all of the little pieces on the front of the sprayer, including the tip, diffuser, and plastic seals.

You’ll need the wrench that came with the sprayer to unscrew the tip!

Step 5: Clean the Small Parts

Then I rinse all of those pieces off and use a brush to get into the tip and any little spaces.

I also make sure there isn’t any paint in the pressure tubes, and if there is I run water through the pressure tubes to get the paint out.

I don’t ever put the whole sprayer under running water!

If there is paint on the outside of the sprayer, I use a wet rag to rub it off as much as possible.

Step 6: Let Dry

And then I set everything on a towel to dry.

That’s it!

Once you get used to the sprayer and all of the pieces, it’s a really quick process!
