I found one of my old airbrushes last night, I thought I'd lost it, haven't seen it in several months!! anyway, there is a wicked clog of red food coloring/lustre dust inside of the nozzle. I tried cleaning it last night with no luck! I've googled "airbrush cleaning" but all of the thinners that are suggested are not food safe. Do any of you know of anything I can use to help unclog the nozzle?

Try kopykake's website

Kopykake does make a airbrush cleaner, if you can get some of that i would try soaking the nozzle in that, if you cant get your hands on some cleaner i would try some vodka, thats what i spray through my airbrush between colors it works great.
