Make sure you get super scene clean not the original. The original will affect plastic

My furnace had a "puffback" several years ago and the result was several dozen models covered with a very fine film of soot. (Not to mention furniture and everything else!) I carefully "painted" them using a half-inch brush and a solution of diluted dish soap and water. I rinsed them all under warm water and let them dry. All of them survived without any damage although it was a lot of work.

i've got one of those super soft makeup brushes that women use to apply makeup with. It's about an inch and a half wide and very gentle. But the best is to use a display case if you can affordit and have rooom tostore it

blast it with the airbrush (no paint, of course...)

I just use a 1" to 1-1/2" paint brush--technically a "trim brush," I think--with soft, fluffy bristles. Natural or "simulated natural" bristles are best (i.e., not the cheap, throw-away brushes with stiff nylon bristles in the hardware store bargain bins). You have to be careful using it around pitot tubes, probes, antennas, gun barrels, etc., but you can get a model clean pretty quickly with one.

Of course, a display case is the best way to keep your models from getting dusty. If you've got the space for one (and the means for lugging it home), you can sometimes get one fairly inexpensively when a store goes out of business and sells off its fixtures.

If you must display your models in the open, it's a good idea to dust them regularly. Dust attracts moisture from the air, and over time it can turn into a sticky, gritty film on the models that's a lot harder to remove.

i have heard of people using the "ink applicators" to get off teh dust. They are like en eye dropper, but are totally made of plastic, and have a big buldge at the top where you squeeze. I suppose if you get a big enough one, it could squeeze out enough air to gently get rid of the dust.

that way you don't have to risk damging your paint, models, etc...

Later

I have dunked my old models into luke warm water with a bit of dish soap, but these all had a clear coat, you dont want to lose any decals or possibly damage a fine paint job made of acrylics.

I use the air cans that are sold for removing dust off of computer of parts, or a very soft flat bristled paint brush.

hope this helps.
