We've been running into a lot of problems the last several years with our laboratory Bunsen burners becoming jammed and/or corroded. I've just come to find out that our lab tech has been lubricating the burners with glycerol, which seems wholly inappropriate to me. I guess she figured that if it worked for inserting glass tubing into rubber holes, it would work for anything. To me, something like a WD-40 would seem more appropriate based on household experience, but I'd like to hear if anyone else has found something for this exact application that works well for them.
I'm currently experimenting with white lithium grease. An engineer friend also recommended Permatex anti-seize lubricant. These seem to work well on a very short term, but we'll have to see how it holds up throughout the next several weeks.
Anyone have a favorite lubricant for something like this?
