Defrost defuser?

Cleaning the inside of this thing is a bear. Can't get the 50 year old nicotine, and THC out of the nooks, and crannies. Would it be best to take all the staples out to give it a good cleaning? Counted 42 staples to replace. Just asking for some options.

I wouldn't, submerge it in some degreaser and let it soak.
