After the attached mini pack of glass cleaner Kärcher window vacuum cleaner was used up was needed replenishment. The first bottle I bought retail at a much higher price. The correct dosage is a breeze, per Kärcher spray are about 1.5 capfuls of cleaning fluid shall be included. If a little more cleaning liquid is considered rather to spray onto the window (so you will not quickly dries) obtained after sucking off a streak-free result. Grease smears, wax sticks, sunscreen (who has children knows these contaminants on the discs) or external contamination of the windows from rain, dust and soot solves the cleaners very good. A difference in cleaning performance and the final result to the yellow plaster Kärcher glass cleaner liquid I could not tell. Determines solve commercial cleaning liquids contaminants also good, but I am satisfied with the result, does not have to experiment with the dosage and get for 3.90 euros a very good, productive cleaner.
Review: + Very efficient + Very good cleaning power for tenacious dirt + Wastage + Streak-free When used correctly, result + Manually applicable
Conclusion: At the offer price of 3.90 euros gets quite cheap a Kärcher brand product that convinces in the Fertility and cleaning performance.
