I need to lubricate the o-ring on my steel water bottle. Is there a lube that is safe to consume?

Vegetable oil? Butter? Lard? They will get rancid, of course, in a very short time.

@gailcalled Those would work, and I clean to bottle once every few days anyway to avoid bacterial build-up. I had thought of olive oil, but am unsure.

^^^. They sound really delicious.

Vegetable oil is better than olive oil.

Astroglide…oh wait, it’s water soluable.
But hey, it works great for lubing lizards stuck in flower pot holes. Yeah, go for the veggie oil or butter.

What about the no stick spray stuff. Pam, I think?

Uhh… a silicone based personal ube? It’s flavorless and non-toxic, but I have no idea how well it works on metal.

At work, we use a silicone mod release agent that is safe for use on things that will come into contact with food.

Vegetable oil and butter can go rancid, and generally have a taste. Most of the kitchen sprays are the same way. Food grade silicone lubes are probably your best bet.

Coconut oil is wonderful.

Silicone lube for sure. I use one for the valves on a water filter system. Look for food grade.or safe for water systems.

If you don’t mind the flavor (of course i don’t because i’m a salt addict- roll it in a bowl of salt making sure some of the salt powder sticks, and it should lubricate fine.

Would some good ol spit work? Some of that stuff you have to work at to get to come up?

Salt is abrasive – no good for seals. I would lean towards olive oil. It takes longer to go rancid.
