Verified Purchase(What is this?)
This review is from: Krcher - 6.291-124.0 - Concentrated Window Cleaner RM 500 - 500 ml (German Import) (Tools & Hardware)
I give 5 stars because it works very well. I would recommend it because it leaves no streaks and is especially successful on south facing sunny windows. Although quite expensive it does seem to go along way.
