I recently came across the Koch Chemie brand and wanted to give them a try. I started with the ASC, and it's a winner! Nice pleasant smell and leaves a very nice finish to the touch. Probably not the best for heavily soiled areas, but great for regular maintenance. The bottle design is also great. Nice size/shape and the sprayer works very well.

I was astonished by this product even in direct sun door panels with no streaks or residue. Compared to other products that leave a haze. GO too

Fantastic results. ASC is easy to use out of the box. Definitely not harsh. I would keep a bottle of this around for daily cleaning, easy touch ups, and use on more delicate items like screens. Will be buying more.
