Do you know if it works on concrete?

I have a stamp concrete driveway and it worked OK. I was not extremely happy with it.

Does this remove the rust drip from jeep rear windows etc.?

I don't know but it works great on white sinks and toilets––nothing like it for removing water rust stains. I'd call their Customer Service to see if it works for your rear windows, etc. But if you need to remove rust stains from fixtures, nothing works better in my experience.

Does this work safely on brick or concrete without taking the color out of the brick? Anyone tried it outside?

I just put some on a brick to test it and it did not affect the color at all. It's never taken the color out of anything I've used it on, including clothes. Does an excellent job getting rid of rust too.

Has anyone tried Whink on colored toilets or tubs?? We're moving out of a rental that has very old blue and yellow porcelin tubs and toilets.

Yes. I used it around the drain of a new bath tub that was shell pink. It bleached the color where it had splashed periphally around the drain. So much for NOT following directions!
