[TheForge] An abrasive product to consider?

[Bruce .]

Recently I came across Scotch Brite (TM) Soap Scum Erasers -- a two-layer
sponge product that touts "Removes stubborn stains without chemicals."  Well
since soap scum was rendering my otherwise fine shower stall rather dingy,
I gave it a try.

The product appears to be abrasive, but extremely mildly so.  It did a find
job of polishing the soap scum and hard-water deposits off chrome,
aluminum, glazed porcelain, and glass in my shower.  The metals came out
gleaming.  I give it an A+ grade for the application.

Accordingly, I wondered whether it might have any application to (fine)
patination.  (Even it if does, there might be much cheaper methods to do
the same thing.)  I'm not in a position to test this, so thought I'd throw
it out for others to consider.

To date, the only place I've found the Scotch Bright product is in Dollar
General stores (and I've looked elsewhere).  I found a similar product in
Dollar Tree (IIRC) called "Scrub Buddies" "2-in-1 Quick Eraser".  A product
found in Walmart, "Great Value" "Miracle Cleaning Eraser" does not seem to
be at all the same.

If anyone tries these on metalwork, I'd be interested.
