Removing Glass Stains with SKRUB

SKRUB is based on a synthetic silica particle of just the right size.  It was created with the intention of helping to remove fingerprints as you applicate.  Just a half an ounce of SKRUB per gallon of soapy water.  It allows you to use a very mild synthetic detergent like lauramine oxide or cocamidopropylbetaine.  There are other very mild detergents out there.  However this is not the only use for it.
Since it is based on glycerin it is very easy to mix with water.  It is also very concentrated.  If you look at the MSDS of certain other commercial liquid compounds used for hard water spot removal, the percentage of silica or DE is very small. Whereas SKRUB is at fifty percent by volume.  Which makes it possible to cut it by at least five times with pure water and still remove water spots.  This I would do by hand.  It will not scratch.  And I have used it to remove aluminum screen stain also.  I do suggest if you intend on using a rotary machine for spot removal then use a cerium oxide compound as this will produce a better more smooth surface.
There are other stains that can be removed by hand with SKRUB when it is mixed fifty/fifty with water.  So it is a good product to have in the tool box for different situations.  In a very dilute concentration with water it can be used with a slow polishing machine and the large Wobble Wheel to "micro-lap" glass surfaces in preparation for certain glass sealants.  This process also converts the glass surface to one that loves water or hydrophylic.  Not hydrophobic.  Hydrophylic surfaces are much easier to clean with a water fed pole.  The process takes about a minute per one to three square feet.
