obviously any type of harsh chemical would be a no-no, but how about rubbing alcohol on a rag? I'm in the middle of installing my HFC, and just curious if I should clean the sensors while I'm at it as they clearly have a nice coating on them

Not sure, but I'm thinking that you can't clean them.

Default I talked to Matt about it on AZ, TP is too stinky for Mrs. Devo
Plus I dont think he'll notice much change between a TP and what he got (Fast Intentions 3" in/2.5" out 300 cell metallic)
