Bookkeeper deacidification spray

At a regional conference last month I say an ad for a deacidification
spray, Bookkeeper.  According to the ad, the nozzle will not clog, it
is environmentally safe and can be used in an open room.  It is a
little more expensive than Wei To, but on the other hand, if you get
to use the whole bottle, and without danger either to yourself or the
environment, it is probably worth the extra expense.  Has anyone on
the list used this product?
