 Hi all!
A silicone based grease (eg. Dow Corning high vacuum grease) is perfect,
but may be tough to find. Try a bearing supply warehouse.  Petroleum jelly
or even generic automotive grease will also work, but even the "waterproof"
petroleum based greases will wash away after a few exposures so you will
have to re-apply occasionally. The silicone based greases are nearly inert,
and will last a long time. They're excellent for lubricating pump seals and
O rings too, and are suitable for drinking water filtration applications.
Hope this helps.
ByeBye! S.
