How can I clean out the crinkly pipes in a forced air heating system?
I live in an RV and am allergic to dust and animals - the forced air heating plays havoc with my allergies. Is there some kind of duster on a flexible rod I could use to get rid of some of the accumulated muck that's doubtless in the tubes? Or something I could stick on the end of a carbon fiber tent pole?
The ducts are about 10' long, curve around 90 degrees (over the space of a couple of feet) and are similar to the vents you get from dryers.
