I want to install a deck plate in the top of the fresh water tank of my camp trailer (RV) to allow for cleaning the inside at the start of the season. The product I am looking at recommends "Lubricate with Vaseline or Teflon grease".
Looking around to see if Teflon is toxic I found this Non-toxic when used in quantities and applications as intended; contains no carcinogenic or hazardous air polluting (HAP) ingredients, and emits no Volatile Organic Compounds (VOCs) but here it is being sold as bicycle lubricant.
When choosing between Vaseline or Teflon to lubricate and seal a potable fresh water tank, which is the better choice?
P.S. Thanks to "RV Geezer" who suggested this in a review I found while looking for a deck plate to use for my boat.
