Review on 🚽 Thetford RV Toilet Seal Lubricant and Conditioner - 24 oz Bottle 36663 by David Cronin

This material is amazing, much better and safer than petroleum jelly for toilet seals. Now you have a person who is good at saying why not use petroleum jelly or petroleum jelly? Now that it contains oil it can cause the rubber seal to swell and not last as long as it could. That's why it's fantastic! Contains no petrol! Advantages: Does not contain gasoline (does not swell the rubber seal) Large quantity (note note) Extends the life of the Toliet seal. The seal extends the life of the bottle. Disadvantages: there are none. I would recommend this product to anyone who has a boat/RV with a vacuum system.
