How salty is our moon, and where is all that sodium going?

My ongoing contributions to the following topics was sadly interrupted by
those silly MI/NSA~MIB, that obviously don't care for having their good ship
LOLLIPOP rocked any more so than absolutely necessary.

OOPS! I've also got yet another pesky mistake of my having used 40e6 m2,
when in fact that physically dark moon and nasty in the rough is actually
worth a surface area of 40e12 m2.
One of my fuzzy work-throughs of improving upon my dyslexic math, as to
estimating upon the mass our moon is losing, as though based entirely upon
supporting the argument of 0.038 m/year worth of satellite recession as
having been caused by the loss of such mass, offers an ongoing receding
energy value of 106.7235e3 joules, or 10.88288e3 kgf = 940 tonnes/day, and
that's worth 343,100 tonnes/year, whereas perhaps the majority of that loss
being in sodium.
That's actually not representing all that much physical loss/m2, whereas the
moon's extremely rough combined surface area of 40e12 m2 (not the 40e6 m2
I'd offered before) is only having to give up 23.5 micrograms/m2/day
(perhaps a double rate of 47 micrograms/m2/day if that loss were limited as
to being extracted from the solar roasted half of the moon).
Of course, once each lunar month is when Earth unavoidably receives at least
a good day or so worth of that sodium mass because, we're directly within
the scope of that solar wind driven trail of such, as the moon passes
between us and our sun. As to how much of the lunar sodium gas our
environment manages to retain is still literally way up in the air.
Since we/NASA (or any other space agency) have never established a scrap of
hard science upon whatever raw elements such as salt or even plain old ice,
as having been evaporated or otherwise demised into less than vapor while
situated in such orbital space as our moon, as for such getting summarily
vacuum boiled and otherwise roasted to death by our sun, as well as
otherwise being hit hard by whatever gauntlet of cosmic influx, as such I
can't offer a better than honest swag analogy as to exactly how much mass
and of what specific raw elements our moon is actually losing.
Perhaps your math and vast resource of supposedly good science is simply far
better off than mine. In which case, I'd like to have your best swag as to
the ongoing loss of lunar mass. Obviously that global warming moon of our's
used to have lots more mass, whereas it originally orbited a whole lot
closer to Earth before getting seriously hammered, and perhaps initially I
do believe that arriving proto-moon of our's could have lithobraked upon
taking a glancing bounce off mother Earth, while having as much as 262 km
worth of salty ice on deck.
