If you are cleaning an outside window, and you happen to notice those annoying dark brown/black raised nubs scattered all over the glass look around. You will likely find some mulch nearby. There is a fungus that grows happily in this stuff that shoots its spores at anything within reach. When they stick they are very difficult to remove. As a window cleaner I have always had to use my razor to get them off. But I would prefer not to if they are on some very expensive tempered glass. Such as sliding doors that cost 1200 bux each to replace. So I found a solution.
I took a flat swivel doodle applicator. Cut it to a 4 by 4 inch square. Applied a repositional tack to it. Then applied a soft glue to a soft cotton towel. And applied a special plastic compositional abrasive. Softer than glass but much tougher than the fungi. The towels can be put on and off the plastic doodle a hundred times. Further I can wet the window then scrub them off. No need for razor blades. While this is not a totally foolproof system (to avoid scratches from tempered glass with a problematic surface) it does work pretty well.
If you want in on this technology just call the Window Cleaning Resource. I have a link on this blog.
