i have never used a "airbrush Cleaner" i have always use window/glass cleaner.. it works a dream and is cheap. at the moment i am using one called "daisy window and glass cleaner" its about 69P for 500ml from tesco.
If it works that is fine Shane. A lot depends on your airbrush seals. Depends if there is anything in the window cleaner the seals do not like. Some airbrushes have seals impervious to most things others not so robust.
Actually I use water to clean my airbrush (complete dismantle to clean 4 minutes flat) & only squirt a half cup of Vallejo Cleaner thro after putting back together. Vallejo has a small amount of lubricant in it. If changing colour I have recently again just used water to squirt thro & then squirted a half cup full of cleaner before adding the new colour.
to be honest laurie, i use a spraymaster airbrush, it was about £80 with a compressor inc, if i had a nice £300 airbrush i would probably use a airbrush cleaner, but i have had it for about 2 years and still works fines.
it was the other thread of the hobby being expensive started me thinking of where i save money ...
shane i use cellulose thinners to clean mine got it from a car repair centre £10 5 litres and it works a treat will clean any paint even if its been in there a couple of days...it just stinks bad
