Maintenance

Cleaning the Interior and Exterior

Clean the interior and exterior surfaces regularly with a mild soap and warm water solution. Avoid abrasive cleaners or scouring pads that can damage the finish. For stainless steel surfaces, use a cleaner specifically designed for stainless steel.

Door Gasket Maintenance

Inspect and clean the magnetic door gaskets regularly. Ensure they are free from food debris and remain flexible to maintain an airtight seal. Damaged gaskets should be replaced promptly to prevent energy loss.
