Used this to clean the window tracks on my apartment windows. So much faster and more efficient than an old toothbrush!

Good design. Use it dry and vacuum up dirt first. Then spray cleaner in groove and clean again. Put thin damp cloth on the groove. Could use paper towel. Using the cleaning brush on top of cloth for final clean.

Complet pour laver les contours de fenêtres au lieu de prendre un couteau

Super super la rail je fait en claquant un coup doigt belle invention

Very effect... Good value

Works great
