Mold or black spots on door gaskets and around the door frame.

Safety: Use gloves and adequate ventilation when cleaning mold. Avoid mixing cleaning chemicals.

Steps:

• Clean gaskets: Wipe gaskets with a solution of mild detergent and warm water, then disinfect with a diluted bleach solution (per manufacturer guidelines) or a commercial mold remover safe for rubber.
• Rinse and dry: Thoroughly rinse with clean water and dry completely.
• Improve seal: Check gasket condition and door alignment. Replace damaged gaskets to reduce moisture ingress.
• Regular maintenance: Clean gaskets monthly to prevent recurrence.
