What can I use that's non-toxic and harmless to the O-rings?
Probably can't be water-soluble either.

Silicone grease.

I use WD40 on everything, and despite being told it won't last, it does.

Silicone grease is the standard lubricant for plumbing. It's non toxic
and does not rot rubber O rings and is safe to use with potable water.

Yes I'd use it if I was putting something together, but to fix
something, a quick squirt with WD40 works wonders.

WD40 is basically a solvent, not a lubricant.
