Microwave interior cavity rusting or paint peeling, especially on the floor or around the door.

Safety first: Unplug the microwave before cleaning or painting. Severe rust can compromise safety.

• 1. Clean and dry: Remove all loose paint and rust flakes with a non-metallic scraper. Clean the area with a mild detergent and dry thoroughly.
• 2. Assess severity: Superficial rust can often be treated; deep pitting or holes in the cavity require professional evaluation.
• 3. Touch-up paint: For minor areas, apply microwave-safe cavity touch-up paint according to instructions. Allow it to cure fully before use.
• 4. Prevent recurrence: Wipe the cavity dry after use and avoid abrasive pads.
