The Product Development Review

SKRUB

SKRUB is a microcrystalline silica particle suspended in pure glycerin.  There isn’t any water added.  Also the microcrystalline silica particle is just the right size and purity such that it will not scratch glass when used by hand.  There is a chance of creating a haze of scratches if used with a machine. Even ultra pure optical grade white cerium oxide can create a scratch haze if used incorrectly with a machine.  I have seen people take dry cerium right out of the box with a rotary felt pad and rip into the glass with the edge of the polishing pad. This and other similar techniques can create a haze of scratches that sometimes are completely invisible until the sun shines directly on the window.  Which is the reason why I developed my Wobble Wheel.  When used in a rotary drill motor it will keep the circular pad completely flat on the glass at all times. 
When using SKRUB with a rotary drill I will first clean the window, then wet it again with a clean soapy solution.  The soapy water will mix with the SKRUB creating a polishing slurry on the glass as you go.  Next I will add about four to six drops of SKRUB to the felt pad.  Then just polish the glass keeping the pad always flat at all times.  NEVER work the glass with the pad turned on edge.  You can soap and squeegee as you go to see if the glass is cleared of stains.  When done just soap and squeegee.  Wipe the edges or at least the bottom edge.  By polishing this way you will use only as much compound as you need, and will reduce the amount of time needed for cleanup. 
SKRUB is also intended for use as an additive for your window cleaning solution.  It can be used at one ounce per gallon of window cleaning solution.  It doesn’t matter what commercial rinse you are using.  Whether that be GG4, Ecover, Dawn, Joy, or some other mix.  You can add enough to an entire bucket and clean the entire window with it.  But the more cost effective way is to have two applicators.  Then use a squirt bottle filled with your favorite solution with a very small amount of SKRUB added to it.  Adjust the concentration to the difficulty of the job.  Then just squirt enough on the applicator and SKRUB just that area of the window that you might have used a razor blade or 0000 steel wool on.  Squeegee to make sure the greasy prints are gone and you have the correct concentration. Next soap up the entire window with the solution in your bucket using the first applicator, and squeegee.  Choose a squirt bottle you can float in your bucket.  Or a smaller one you can fit in your pocket. 
Another application for SKRUB is screen stain.  I will make up a concentrated solution of SKRUB in a squirt bottle.  Then I will SKRUB a clean window that has “screen stain” on it.  This is the stain that develops from aluminum screens.  You can use a sponge, or 0000 steel wool.  Then soap and squeegee again. This is the most safe way to remove screen stain.  If you treat the surface with a sealant like Rain X, when the stain returns one year later, it will be much easier to remove using SKRUB. And the Rain X will usually remain.  If not just reseal.  You will know when you are breaking through the stain because the solution of cleaner and SKRUB will start to bead up.
