Dust, pollen, insect residue: Not a problem with a good windscreen cleaner – bad ones, on the other hand, can attack a car’s paintwork and plastic. A new test reveals.
More expensive doesn’t always mean better: In a new windscreen cleaner test by specialist organization KÜS, the highest-priced products aren’t outright bad—but they aren’t actually any good either. And at least in this comparison, the cheapest cleaner is also the worst.
By the way: KÜS is advertised for the Automotive Monitoring Organization of Independent Automotive Specialists.
Test loser ditches the plastic
Nine treatments were encountered in the KÜS trial. the best cleaner comes sonaxThen Nigrin, Liqui Moly, and Dr. Nirala all four performed “well”: they have no problem with city dirt or insects, and they also don’t attack paintwork or plastic.
The cleaners of Mannol, Caramba and RS 1000 are “satisfactory”. Mannol’s agent cleans well, but isn’t ideal for paintwork: It caused a bit of swelling in testing, but can be polished off, according to KS.
Caramba cleaners have a problem with insect infestations and smell very unpleasant. The RS 1000 already has a tough time with city dirt, it also fails as the insect leaves residue and infiltration on the plank.
