Freezer interior surfaces show rust spots or bubbling paint.

Safety first: Unplug the freezer before working inside. Avoid inhaling dust from rusted areas.

Step-by-step checks:

• 1. Clean area: Remove loose rust with a plastic scraper and wipe with a damp cloth.
• 2. Dry thoroughly: Ensure the area is completely dry.
• 3. Touch-up coating: Apply a food-safe appliance touch-up paint or epoxy suitable for freezer interiors to seal the area.
• 4. Prevent recurrence: Avoid leaving standing water or spills inside the freezer and use only mild cleaners.

When to call a technician: If rust has penetrated deeply or the liner is perforated, professional assessment is needed; replacement may be more economical.
