Up at The Paint Sprayer Guy HQ, we have a cheap Wagner W100 paint sprayer. Unfortunately when I dug it out of its hidey-hole and had a look at it the sprayer was in a right state. This is what I get for not cleaning my tools properly after use.

The last thing I sprayed through this thing was Hammerite, about 6 months ago, and as you can see, that Hammerite has now dried all over the damn thing.

As Winston once said, never let a good crisis go to waste! So I decided this was a great chance to show you guys how to clean a paint sprayer. And that even when they are in such bad condition these sprayers can be brought back to life.

Cleaning The Sprayer

Before I could even begin to clean the inside of the sprayer I had to try and get into it. Easier said than done as the paint had pretty much welded the paint pot onto the sprayer.

I started by using some paintbrush restorer to try and break up that dried old paint.

This stuff is great at bringing fully dried paint off your brushes so I was optimistic it would work here too.

You can see that it is already having an effect, peeling off the paint at the top of the sprayer. But I needed it to penetrate under the lid and break the seal that had formed.

A few applications later and you can see that the paint is really starting to break up.

Finally, the lid is off. The brush restorer and a good twist in a vice did the trick.

Now that the central part of the sprayer has come apart we can start cleaning all of the smaller pieces that have got clogged up with paint.

Again I will use a paintbrush restorer to remove the paint from all these parts.

Looking nice and clean now. This tube is used as a pressure release, I think??

This is the tube that feeds all the paint up into the sprayer. As you can imagine this was seriously blocked.

This is what it looked like mid-clean after I had already removed a vast amount of dried-on paint.

So after taking all the individual parts out and soaking and scrubbing them with a paintbrush restorer this is what the sprayer looked like.

It’s looking a lot better now!

That did the trick and now the sprayer works great, look out for some projects incoming using this Wagner W100 sprayer!
