Deep Clean Your Gravity Feed Airbrush

Why should you deep clean your gravity feed airbrush?

It's just like sending your airbrush off for a factory overhaul.
It's easy. Well, maybe not the first time through.
Deep cleaning your airbrush is far faster than sending it back to the factory--unless, of course, you're right next door...
When other cleaning methods fail to resolve a problem, a deep cleaning is the next, and usually the last troubleshooting step.

This particular guide applies to these airbrush models.

The Guru's Tips for Your First Time Through This Guide

Set aside an hour.
A good, thorough, deep cleaning might only last five minutes if you know what you're doing. But this is your first time through. There's new terminology, it might be your first time taking the airbrush apart, for whatever reasons, set aside the time. It will probably take far less to finish but that's okay because...
Take your time.
The first time through this guide you might get a little confused. It's okay. Figure out what's going on and keep on moving, because you'll also need to...
Be Thorough
By, "Be Thorough" I mean be an obsessive compulsive clean freak. People who are a touch OC do airbrush maintenance very well. ;)

I tell people to clean their airbrushes a second and even a third time because I understand the difference between what most people think a clean airbrush is and what a clean airbrush really is.

It took me three hours and 4 "do-overs" to get my first airbrush clean. Kirk and Gary wanted me to know what a clean airbrush really is.
Frustration Happens

Get up. Walk away. Go do something else. Bad Things happen to airbrushes when you're frustrated. Trust me, I still get frustrated. As soon as I realize it I go take a break.

Come back with a fresh mind and attitude. Don't worry, you'll get it, but if not...
Call Up Tech Support
Airbrush importers and manufacturers want you to succeed. Most of them have technical support lines to help you work through whatever problem you're facing.

Needles are Sharp!
They hurt going in and if they hit bone they hurt even more coming back out--don't ask me how I know that...

That means...

If the needle drops to the floor DON'T CATCH IT WITH YOUR HANDS OR LEGS! You can learn the lesson from my warning or by finding out for yourself...
Nozzles are Delicate
Be gentle. After cleaning, the second most common airbrush problem is nozzle damage. The most likely time to damage that nozzle--is now.

Some nozzles look like they can screw apart. They can, but don't do it.
Only Clean Places Paint Goes
Bottles, cups, the outside, and the paint passage are all you need to worry about without a specific reason. Cleaning out other areas, like the trigger housing or the air valve can result in a few unexpected problems.

Towel or tray to work over

To catch things that drop. Small pieces are really good at hiding.
Appropriate cleaning solution

Generally it's your paint's reducer, or 'base'. Alcohol based paints tend to dissolve in alcohol, water-based paints in water, etc. Sometimes, especially for water-based paints, there are other cleaning solutions that work much, much better than just plain water. Don't use anything with ammonia in it.
Round wooden or bamboo toothpicks

You might need some sand paper or an old nail file here as well depending on just how sharp the toothpicks are--you might need to make them sharper.
Bristled cleaning brush or....

Interdental brushes (personal favorite), Airbrush cleaning brushes (you'll need the small ones), or pipe cleaners (not recommended)
A crescent wrench
Cotton swabs for general cleaning

Note: Cotton swabs do occasionally shed their fibers, if it does just make sure you pick them out
Mirror or mirror-like surface

Old AOL CDs are my favorite "mirror-like surface" but if you're cleaning with a solvent CDs won't last long. In that case use part of a glass mirror.
(Optional) magnifying glass or jeweler's loupe

Start cleaning the nozzle with a brush

and finish with a toothpick...

This is the important piece, make extra special certain it's clean.
Clean the paint passage at the front of the color cup with the cleaning brush
Clean the front of the airbrush body. Pay special attention to the place where the nozzle sits.
Clean the color cup. Cotton swabs or paper towels both work fine here.

NOTE: Clean everything very thoroughly! I know you're getting tired of me saying it. But I harp on it because it really IS that important!

Place the nozzle onto the airbrush body.
Screw the head cap over the nozzle onto the airbrush body.
Lightly tighten the head cap with the wrench, no more than a quarter turn.
Screw the nozzle cap onto the head cap
Screw the needle cap onto the nozzle cap
Gently insert the needle. It should come to a firm stop with the needle tip poking out of the front.

Do not force it in.
Twist the needle counter-clockwise a quarter turn
Screw the needle chucking nut, big end first, onto the needle chucking guide
Screw the handle onto the back of the airbrush body
