1. Fire Hazard
Ovens generate extreme heat. Placing a tea towel on the door can cause it to catch fire, especially if it’s near the oven’s heating elements or if the oven is left on for an extended period. Even a short exposure to high temperatures can ignite fabric.
2. Heat Obstruction
Covering the oven door can trap heat around the door or interfere with proper ventilation. This can reduce cooking efficiency, cause uneven baking, and in some cases, damage the oven’s insulation or glass door.
3. Steam and Moisture Damage
