It won't let anything burn! The KitchenProfi ceramic glass cleaner gently and thoroughly removes dried-on residues from your cooktop. Inside the handy housing made of high-quality plastic, there is a blade that tackles dirt while treating the surface of the stove gently. Position the cleaner at the desired angle and apply light pressure. If more force is needed, replacement blades can be used. When not in use, the blade safely retracts into the housing. This reflects the thoughtful design by Ralph Krämer.
