I forgot to address this point ... Calcium carbonate is not a detergent
(which is a good thing since it's the major ingredient in Tums), it's also
known as Calcite or limestone. It's the abrasive in Bon Ami Cleanser (but
not in Bon Ami cleaning powder) that is harsh enough to scratch glass. Both
have feldspar (which is actually a generic name for a group of very soft
minerals), but only the cleanser has calcite.
And I assume we're all clear that dumping this stuff down the intake is not
a normal thing to do, rather it's a last ditch effort before tearing the
engine down again.
