Recently, while doing an emergency water heater replacement, I needed some lube for the small O-rings on the mixing valve. Realizing I didn’t have any silicone lube in my solder box, and not wanting to take the chance of tearing the rings, my imagination kicked into gear. I remembered I had a stick of Burt’s Bees lip balm in my truck. The all natural beeswax was easy to apply and worked perfectly.
