WelshZeCorgi Posted April 9, 2018 Share Posted April 9, 2018 After not painting for a month, (too cold), it started warming up again. When I tried painting, I found the needle wouldn't move. After further inspection, I found that the needle was effectively glued to the inside of the "barrel" of the airbrush. I had to pull the needle out with quite a bit of force, pushing it forward a few mm before pulling it back a few mm, then push it forward a few mm and back a few mm before it popped out. I'm unsure if this caused damage to the airbrush. But I found dried paint caked on the portion of the needle that rested behind the paint cup. (Where I'm pointing) https://photos.app.goo.gl/JLVqgHK7E3wk8iht2 I've did my best to clean that area out, using a pippette to push cleaning fluid up that channel with the needle removed, but it still got caked with paint. How do you guys clean your airbrush to get all the paint out of that barrel behind the feeding cup? Quote Link to post Share on other sites
spejic Posted April 9, 2018 Share Posted April 9, 2018 You shouldn't be getting paint there from just the normal operation of the brush. You are probably introducing paint there by pulling the needle out through the rear when you clean the airbrush. This not only puts paint in a hard-to-clean place, but it might eventually get in the air valve, which is tricky to disassemble and clean (or, more accurately, easy to disassemble and clean and a pain to put back together). I always remove the nozzle and push the needle forward when I clean. Quote Link to post Share on other sites
ElectroSoldier Posted April 9, 2018 Share Posted April 9, 2018 Ultrasonic cleaner might help. Its not easy to clean in there. Pull the needle out the front after taking the nozzle off rather than out the back Quote Link to post Share on other sites
Mstor Posted April 11, 2018 Share Posted April 11, 2018 Don't know where you are located (country wise), but Model Paint Solutions sells a 6 piece airbrush cleaning kit that has some very thin brushes that fit down the small channel that the needle runs through. I recently bought this set and used the smallest brush to clean the channel in my H&S Infinity. Worked like a charm. Here's a link: https://modelpaintsol.com/model-paint/6-piece-airbrush-cleaning-set I have no connection with Model Paint Solutions. I am just one very satisfied customer.

admiralcag Posted April 11, 2018 Share Posted April 11, 2018 What Mstor said. Also, before throwing it in the ultrasonic cleaner, you need to remove your o-rings and packings. Iwata makes a special tool set that allows you to get them out easily - https://www.amazon.com/Iwata-Medea-Iwata-Professional-Maintenance-Tools/dp/B019EGII40 Vern Quote Link to post Share on other sites

Don Wheeler Posted April 12, 2018 Share Posted April 12, 2018 There is a channel between the cup and the needle seal where paint can collect over time. You can see a sketch on this page. If you use an interdental brush like this you can clean it out from the cup. It only takes a second and it's a good idea to do it each time you clean. Yanking a stuck needle is a bad idea. You may have damaged the needle seal which can result in a leak into the rear of the brush. If you pull the needle and wipe it each cleaning it won't get stuck. The best solution for a stuck needle is to remove the head and nozzle, put a few drops of lacquer thinner or acetone in the needle channel, let it soak for a few seconds and then try pushing the needle forward.

zeus60 Posted April 17, 2018 Share Posted April 17, 2018 I get paint in that part of the airbrush every time I use it. I'll have to try the remove the needle from the front next time. Quote Link to post Share on other sites
ElectroSoldier Posted May 14, 2018 Share Posted May 14, 2018 Airbrush cleaning brushes. There are "solid" wire versions of the same then an UltraSonic cleaner to tidy up Quote Link to post Share on other sites
