Hi, Sheffey
I saw a TV documentary about how toxic teflon is, and how it cannot be broken down once in the environment.
I replaced my teflon powder with 100% talcum powder, and handed in the teflon spray cans at a hazardous waste event.
I had already gotten rid of teflon coated frying pans, because I'd heard that the vapors from them can kill pet birds when they are heated up, so obviously they aren't benign.
So, a little bit of convenience is gone, but I find I can live quite well without teflon.
Maybe another lubricant could be rubbed on the keypins.
