Yikes!
Please, no soaking!!
Wiping with a damp cloth(well rung out) after wearing will remove traces of makeup, store apart from other jewelry that might scratch them, for starters.
Somewhere here on the Forum is comprehensive info on pearl care and storage, try the search, please.
Websites of our seller members, list useful care tips, which are very consistent and apply to all types of pearls as they sell everything from FW to Tahitians, try checking PearlsofJoy, Purepearls, PearlParadise, just to name a few.

Aha, there it is, in the column just to the left, blue color printing, toward the bottom "Caring for Your Pearls"
