I have the Hampton GCI60 pellet insert. I've always used a brush to get in between the heat exchanger tubes which produced a ton of ash falling down.  I did this after using the scraper rod to knock some off before opening the door.  The brush I used was actually an old potato brush with a handle and then a loop with bristles on all sides. It was the perfect thickness to get in between the tubes to knock down ash. 
Anyhow, it broke and I cannot find another one of these cheap brushes.
So, i'm curious what other people use to get up there.
thanks for any input.
