Just got done with my 2nd smoke with the wsm and took a peek at the inside lid at the thermometer probe,
is it necessary to clean or wipe that off after a few smokes? thanks.
I've never really given any thought to giving the temp probes a wipe down after doing a smoke. I run a Lang that has two thermo probes on it, a GOSM that has one and an electric UDS with one in the lid and a propane grill. Never cleaned a single one of them. The only probe that gets cleaned is the food probe from my digital thermometers.
I bet most of the folks that answers this will tell you that they don't clean the cook chamber probe either.
I just came in from cleaning out the grease and gunk from the inside of my smoker. I always wipe off the stems of my therms. I don't know if makes any difference as far as reading the temps properly or not, but I figure if I'm going to all the trouble to clean the smoker, what's it going to hurt?
Doesn't cost anything to wipe them off.
As long as the coating isn't too heavy & gross, it's good to leave it. Keep the cooking grates clean though.
I can only speak from my experience on the subject. I have a GOSM big block, with three temp gauges on the door. While cleaning the racks, I decided to clean the therm stems too. I did notice a difference in the readings. So now, whenever I clean the racks I also clean the therm stems. I use an oven type cleaner, then rinse with water. I finally light the GOSM, and make sure that everything is dry before I smoke anything. It's all good my friend.
