Full Crystal Glass + Window Cleaner

James Daly
It doesn't shut off.

The item never shut off. All of it emptied out on the first window.

Lynne Bowen

It was good on new dirt.
We have minerals in our well water and it didn't clean that off

Jay Buttross

It did not do the job. I live in Texas we get much dust. I will try again when the weather cools a bit. This product was recommended by our friends who live in Ohio. I am open to suggestions

Eileen Thiel
I didn't care for it at all.

I didn't care for it at all. It made me extra work. I followed the paper that was send. When I finished I had to go back and wash all the windows with Windex. It was a very costly mistake buying.
