New to low-e coating. Saw this today, can I steel wool it

What is the recommend cleaning for this.

Is the Low E coated surface exposed, if so then no steel wool, if not doesn’t matter.

I couldn’t tell really. It didn’t look or feel any different than any other glass I have cleaned. So might be on the inside.

You would know straight away it has 4 times more drag than a film tinted window.
