Edit: Sorry Wrong link should be aerosol Invisible glass cleaner (without the rain repellent)

best way to clean it is with a Squeegee, the water blade is great,leaves no streaks

I've had really good luck cleaning it off with a good microfiber cloth and just water.

You need to rub a bit but the fibers of the cloth due a great job without any cleaner.

I was surprised myself...................

i use sprayway glass cleaner and water blade,i cant use microfiber ,always touch shield..rag moves and hand rubs and makes more of a mess lol

I hear ya on that! lol The cloth I use is actually a floor dust mop, its really heavy fiber
with lots of texture to it. The good thing is it has little pockets on the backside of it, where the dust mop head would fit in. You can use them much like a glove to get a good grip on the sucker.
