[H MAN]

Material we are using works like steel wool SCRUBS JUST AS WELL "BUT" does not RUST OR SCRATCH THE GLASS.
This video will show you what tools and materials you need.
How make and fit the scrubbing sleeve to the T Bar.  We have been using this scrubbing sleeve for number of years now.
With chemicals like CC550, One Restore many other chemicals that would other wise ruin your standard scrubbing sleeves.
Good when doing first cleans not only windows but other surfaces.
And will out last any window scrubbing sleeve on the market.
