Breaking in Coralife Deep Six Hydrometer

I got lazy and didn't rinse out my hydrometer and had some salt build-up. I gave it a vinegar bath, I remember I had to "break-in" the hydrometer but don't remember how (threw the package).
Any help?

I've done this and just left mine (not Coralife) in my RO top up tub of water to soak overnight. comes out looking like new.

FWIW I think these are all crap though. I took two different ones to LFS, compared to two of theirs and ALL 4 were giving very different readings, with a high and low spread of about .007!!!!

So I think these are only good for relative readinbgs week to week.

I'm looking for a good deal on a calibratable electronic unit.
