Review on Kärcher 500ml Window Vac Glass Cleaning Concentrate by Ada Nadolna ᠌

I hoped for a super effect, because the brand in which I had no doubts. I washed it by hand, which actually allows the remedy, diluted first 1:10, then 1:5, then I tried it with a cleansing agent. The entire window remained dirty and greasy stains, the first rain showed that the traces of the drops are visible gorgeously and do not roll down at all. It was easier to buy an ordinary glass cleaner more expensive, but then Karcher ! The bottle has no protection, no plastic ring, no film, the smell is weak
