Karcher Window Cleaning Concentrate

Kärcher's new 500ml window cleaning concentrate gives streak-free results on all waterproof, smooth surfaces such as windows, glass, mirrors and shower screens when used with a Kärcher Window Vac. The detergent is formulated to help rain run off windows faster, decreasing the likelihood of marks and streaks whilst delaying the resoiling of dirt so you don't have to clean as often.
