Safe grease to use in taps

[Chapster]

Hi, wonder if any plumber here can tell me what is the usual grease used to lubricate tap valves?

My kitchen mixer tap quarter-turn knobs are hard to turn, causing the whole tap to revolve. I want to remove the tap inserts, clean them and grease them up, but don't know what grease is safe to use for potable water.

I'm pretty sure the lithium grease I use on the car is not suitable...

Thanks

Silicone grease

Vaseline is as good as anything

Didn't think of Vaseline. So many uses...

I have silicone grease but a check of the datasheet shows it's toxic.

Plumba silicone grease and other potable water greases I finally managed to find claim to be of low toxicity with no effects from ingestion, etc.

Yeah, that's what the French tell you....
