Is this tomfoolery?

Steel wool won't harm glass, UNLESS abrasive particles are already present on the glass. Unfortunately, aluminum oxide is common in "dirt." It won't take much aluminum oxide to scratch glass. So, before polishing glass, remove the bird poop and dirt with lots of water, detergent and a soft cloth. Then, polish with a commercial compound intended for that purpose, like:

You are talking a Class 1 (or 2 min) clean room bud. Same place they assemble your iPhone. Being your profession, Dave, you know as much as I do it won't work outdoor.

Don't have the material hardness links handy for steel but believe me, you don't want to scratch glass with that. Naked eyes won't catch the damage, but magnify this x100 and you'll have a heart attack
