Fraud. Four strokes of the wipers and the windshield is clear!
At the turn of May and June 2019, the Dekra laboratory in Stuttgart carried out comprehensive tests of the latest formulation of Psik Psik winter windshield washer fluid.
Dekra, Europe's largest certification body, has been working around the world for almost a hundred years to improve safety on the road, at work and at home. Among other things, it conducts the most thorough research on windshield washer fluids in the world. It checks all physical and chemical properties, and also examines the effect on the elements with which the liquid comes into contact (for example, car paint, rubber elements, plastic elements, car headlights), freezing point and performance properties, including the most important - cleaning properties. . The latter are tested in a special chamber in which a constant negative temperature is maintained. A specially prepared mixture is applied to the glass, imitating winter dirt, then the effectiveness of the liquid in removing it is checked.

In these tests, Psik Psik liquid confirmed its performance and safety - no negative impact on all elements of the car body: all unpainted and varnished coatings, rubber and plastic elements, as well as car headlight housings, including xenon and LED. It is important to note that it got a very good result in the dirt removal test - 3,7 wiper cycles to a state defined by Decra as “free look”, i.e. no dirt on the windshield. This is a very important parameter that directly affects the safety and comfort of driving in difficult winter conditions.
Dekra awards a "very good cleaning performance" result for winter windshield washer fluids with less than 7 wiper cycles. A result of 3,7 wiper cycles is the best result ever achieved by a Polish manufacturer's fluid, and the second best result ever for Dekra's European winter windshield washer fluid test.
