Question from the guy who never paid attention in science class:

Does soaking un water hurt magnets?
Thinking of re-basing some guys I have mounted on magnetic bases with white glue. When I rebase, Ijust soak in water for a bit and everything just pops off.
That won't hurt the magnetic base will it?

I looked out the window during science so I don't know the technical answer.
But I have done what you are proposing and the drowned magnets continued to work.

If your magnets dissolve in water, they weren't very good magnets… ;-)

That won't hurt rare earth magnets, and doubt it would have an affect on magnet sheet or the cheaper rubberized magnets either.

Water won't hurt them unless it's boiling or near ice. Magnets don't like sudden changes in temperature- particularly heat. Being struck or high-energy electric (AC) fields also damage them. Dry them with paper towel when you've finished stripping the bases and you shouldn't even have any rust problems.

Well, magnets are made of iron, and water causes iron to rust, so if you put a magnet into water and it rusts…

Dunk her again for good measure!

Most rare earth magnets have a coating – (nickel, copper, chromium, and others) to prevent them from oxidizing.

Now the old kiddie-style magents……

ugh, which magnets are the worst? That's right, witch magnets.

Be careful though: the water will become magnetized and will stick to the drain!
