i like the brew rite stuff personally I dont think it does much for the actual coil but its easy and cheap and a once a week bath seems to keep the mesh nice and fresh for absorbing liquid.
I think a real key to maintaining a atomizer might be just to keep the
juice flowing to the coil unobstructed. thereby keeping the coil running cool.
also btw did we ever figure out what the crud buildup on the coil was? I had a thought the other day that it might be dust/dirt thats in the air being sucked into the atomizer.
Most of the dust we have in our houses is made up of shed skin cells and since we are mostly carbon it would only make since that when this dust is burned onto something it carbonizes.
Maybe we need to make air filters for our attys to keep the dust out.
