how do you clean the inside of this fridge without ruining it? the manual is vague and i'm scared of the plastic.

Diagnosis

The interior liner of the Midea WHS-65LB1 is constructed from a high-impact polystyrene (HIPS) plastic. While durable, this material is susceptible to "crazing"—the development of microscopic cracks—when exposed to volatile organic compounds (VOCs) found in bleach, ammonia, or citrus-based degreasers. If you use a scrub pad or a magic eraser, you will strip the glossy protective finish, leaving the plastic porous and more likely to absorb food odors and stains over time. Furthermore, because this is a compact 1.6 Cu Ft unit, the drainage system is minimal. If you use excessive amounts of liquid or high-pressure sprays, water can seep into the insulation or clog the small drain hole at the rear, leading to internal pooling or ice buildup on the evaporator plate. You can confirm if your liner is already damaged if you see a "cloudy" matte finish in areas where you previously used harsh cleaners, or if you notice small, spider-web-like cracks near the door gaskets.

How to Fix It

To deep clean the unit without compromising the structural integrity of the plastic, follow this precision sequence:

1. Disconnect the power cord from the wall outlet. This is critical not only for safety but to prevent the thermostat from triggering the compressor while the door remains open for an extended period.
2. Empty the entire cavity. Remove the glass shelf and the door bins. If the door bins are stubborn, pull them straight out—do not twist them, as the plastic tabs on the WHS-65LB1 are prone to snapping if torqued.
3. Prepare a non-reactive cleaning solution. Mix 2 tablespoons of a pH-neutral dish soap (like Dawn) into 1 quart of distilled warm water. Avoid boiling water, as extreme temperature shocks can warp the thin plastic liner.
4. Apply the solution using a microfiber cloth or a soft sponge. Dampen the cloth, wring it out so it is moist but not dripping, and wipe the interior walls starting from the top and working downward.
5. For stubborn stains or dried spills, do not scrub. Instead, lay a soaked microfiber cloth over the stain for 5-10 minutes to rehydrate the residue before gently wiping it away.
6. Rinse the interior by wiping it down with a fresh cloth dampened with plain water. This removes the soap film which, if left behind, can attract more dirt and create a sticky residue.
7. Dry every surface immediately with a clean towel. Ensure the area around the evaporator plate (the cooling element) is completely dry to prevent premature frosting.
8. Reinsert the shelves and bins, then plug the unit back in.

If That Didn't Work

• If you are dealing with persistent odors (like old milk or onion) that soap cannot remove, mix a solution of 1 part white distilled vinegar to 3 parts water. Wipe the interior and let it sit for 15 minutes before rinsing. The acetic acid neutralizes odors without etching the plastic.
• For "sticky" residue that refuses to budge, create a paste of baking soda and water. Apply the paste to the spot and let it sit for 30 minutes. Gently wipe away with a damp cloth; the baking soda acts as a mild abrasive that is softer than the HIPS plastic.
• If you notice mold growth in the door gaskets (the rubber seals), use a cotton swab dipped in a 10% bleach solution. Apply it ONLY to the rubber, avoiding the plastic liner entirely, then wipe clean with water immediately.
• If the interior has a permanent "plastic" smell, place an open box of activated charcoal or a bowl of dry coffee grounds inside for 48 hours after the cleaning process is complete.

Heads Up

• Never use steel wool, scouring pads, or abrasive "magic" sponges; these will permanently scratch the liner and make it more susceptible to bacteria.
• Avoid using any spray cleaners containing ammonia or bleach, as these can cause the plastic to yellow or become brittle over time.
• Check the rear drain hole during cleaning to ensure it isn't blocked by food debris, which prevents the fridge from defrosting properly.
• Always wait for the interior to reach a stable temperature before loading it with chilled items to avoid putting undue stress on the small compressor.
