Make sure that the rubber inserts of the brushes do not pop out of the holders, otherwise the wiper will scratch the glass. Moisten the glass with washer before turning on the wiper (if it's dry), otherwise the brushes will scratch the glass.
If during the operation of the wiper on the glass there are uncleaned places, stripes, gaps, replace the brushes or rubber inserts.
You can replace the rubber brush inserts yourself. Replacement instructions are attached by the manufacturer to the set of rubber inserts.
Clean dirty brushes with a damp cloth.
