Freezer interior surfaces show rust spots or paint bubbling.

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

Assess damage:

• Identify all rusted or bubbled paint areas.
• Ensure there are no actual holes through the liner exposing insulation.

Clean and treat:

• Lightly sand rust spots to remove loose material.
• Clean with a mild detergent and dry thoroughly.
• Apply an appliance-grade touch-up paint suitable for cold environments.

Prevent recurrence:

• Avoid using metal tools to chip ice.
• Wipe up spills promptly and keep the interior dry.

Note: If rust has penetrated through the liner, structural repair is complex and may not be economical; consult a professional.
