These components can be washed with warm soapy water and allowed to air dry. This helps prevent any lingering moisture from promoting bacterial growth.
To clean the exterior of your Subzero, mix a solution of equal parts water and white vinegar in a spray bottle. Spray the solution onto the exterior, paying particular attention to any areas with visible stains or splatters.

Preparation
Before you start cleaning your subzero refrigerator, it's essential to prepare yourself and the space. Gather all necessary cleaning supplies, including a microfiber cloth, a mixture of equal parts water and white vinegar, and a soft-bristled brush.
Removing magnetic strips and shelves will give you better access to all areas of the fridge. Don't forget to take out any drawers or baskets as well.
Take out all contents from the fridge and sort them into categories, such as leftovers, expired items, and items that can be stored elsewhere.
Check the expiration dates of the items you're removing and dispose of any expired or spoiled food. This will prevent any unpleasant odors and messes during the cleaning process.
Set up a designated area for the items you're removing, such as a countertop or a separate container. This will keep the area organized and make it easier to put things back when you're done cleaning.
Exterior Cleaning
