Air abrasion using baking soda

From: Gordon A. Lewis <*gal<-a*> Date: Thursday, April 21, 2005 · gal<-a

I recently saw a demonstration of baking soda as an abrasive to
remove many different accretions; it seemed interesting. The
demonstrators told me it is in use in dentistry and other arenas.
According to their literature, baking soda has a MOHS of 2.5 and can
be used in dry or wet applications. Has anyone used it; have any
experience; knowledge?
