I have a 10 year old mount of a woodcock, resting on a wooded base. The base has all kinds of delicate details such as leaves, grasses, forbs, twigs, and dirt. I have been able to keep the bird itself dust free BUT my question is HOW DO I GET THE DUST OF THE BASE AND ALL THE EXTRAS. It is very fragile.

I understand is difficult, usually I use my air compressor and blow air very slighty over it, and also use a 2 inch soft paint brush to dust it, you just need patience and do it slow.

Can of compressed air like they use to clean computer keyboards. Hope it helps

That is what I do
