Always spray or splash water first
Make sure the surface is completely wet. This reduces friction and prevents scratching.
Hold at a shallow angle (15°–30°)
Keep the blade almost flat to the glass or surface.
Use gentle, even strokes
Let the blade glide — never dig or use pressure.
Wipe away residue immediately
Use a clean SHYN microfibre or drying cloth to remove loosened grime and water.
