The problem is, Windex, 409, cloth soaked in clean dish water with
detergent is a widely  used cleaner, for piano and finished wood surfaces.
 Not to mention Murphy Wood Oil, and many brands of "non phosphate"
cleaners. These can leave streaks unless really pursued digilantly.   For
these streaks a common treatment for satin black finishes is lemon oil,
which imparts a sheen but doesn't last and imho collects dust &c.    Could
you recomend a cleaner for satin finishes before using the #12 balck
rubbing compound and 3/0 steel wool?

Therefore, not good for pianos--just windows.  This wax will need to be
re-applied to get the satin black color back.  There is no need to use
steel wool in the cleaning process.

That could lead to some real trouble.  It's like advising an owner to try
tuning their own piano with a socket set, or even the proper tools.
