1 Prepare for safe work
Ventilate the room, put on gloves, and test the cleaner on a hidden area first. Protect children, pets, and sensitive surfaces.
⚠ Warning: Never mix bleach with vinegar, acids, ammonia, or other cleaners. The mixture can release toxic gases.
2 Determine the exact symptom
Work when the glass is not hot from the sun. Remove dust from the frames, seals, and glass before applying water.
3 Check the most common cause
Operite staklo malom količinom rastvora i čistim brisačem povlačite preklopljene poteze odozgo naniže, brišući gumu nakon svakog poteza.
4 Resolve the cause without improvisation
Dry the edges with a clean microfiber cloth and inspect from two angles. Wipe streaks on the inside and outside in different directions.
? Tip: Photograph the initial state and change only one thing at a time. This makes it easier to recognize what really solved the problem.
5 Test the result
Remove product residue according to the label, dry the surface, and inspect the result in daylight. If the problem returns quickly, find the source of moisture, dirt, or pest entry.
