I'm using a bottom fed Badger airbrush. Usually when I forget to clean the cup, the paint dries in a thin film. Over the months it accumulates and is really hard to remove even with thinner.

Then one night I filled the dirty cup with rubbing alchohol for some other reason then left it standing the whole evening. Well the next morning the paint was loosened and I was able to restore the cup as if brand new. I was so happy that my cup was clean and shiny again.

one more bit of information would be helpful...

what type of paint....

tamiya acrylics? (my guess)..

model master Enamals.. model master acrylics, polyscale acrylics.. humbrol enamal...


inquiring minds want to know..

I use enamels 90% of the time. Humbrol mostly then Testors/MM and some Tamiya enamels.

hmm I may just have to give this a try I got a few grubby bottles that need a cleaning.........
