Clean the refrigerator door gasket for a better seal.

The flexible gasket around a refrigerator door needs a clean contact surface to seal properly. Food crumbs and dried spills can keep sections from lying flat, while harsh cleaners may damage the material. Use this gentle routine after checking the care instructions for your refrigerator model.

What you’ll need

• Owner’s manual or model-specific care guide
• Warm water
• Small amount of mild dish soap
• Two soft microfiber cloths
• Soft toothbrush, if permitted by the manual

Take it step by step

1. Move food and door bins only as needed to reach the gasket comfortably. Keep the refrigerator door open for the shortest practical time.
2. Inspect the full gasket and the cabinet surface it touches. Look for crumbs, sticky residue, folds, tears, or sections pulling away from the door.
3. Mix a small amount of mild dish soap with warm water. Dampen a soft cloth, then wring it well so water does not run into seams or controls.
4. Wipe the gasket gently, including accessible folds. Use a soft toothbrush only if your model’s instructions permit it; never scrape with a sharp tool.
5. Wipe the matching cabinet surface with a separate damp cloth. Follow with a clean cloth to remove soap residue, then dry both surfaces.
6. Close the door and check that the gasket meets the cabinet evenly around the perimeter. Repeat the inspection on other refrigerator or freezer doors.

When to ask for help

Arrange qualified appliance service if the gasket is torn, will not stay seated, has a persistent gap, or the door remains difficult to close. Also seek help if food is not staying cold; cleaning alone will not diagnose a cooling problem.
