Wurth makes a very good product for cleaning a/c lines & ducts. If your fan box is dirty, that should do the trick. There are bound to be competitors if you can't find Wurth's product.
I'd spray it liberally and use a rag as best I could. Industrial grade Q-tips (from an electronics store) would likely help. A tiny vacuum attachment would be nice too. An airgun might even help. At least that's what I'd try - in no particular order.
