Even if it's been a while, cleaning your LG refrigerator is fairly easy. You'll need some gloves, detergent, baking soda, vinegar, and clean, warm water. Do not use chemical cleaners. Ready to start? Let's go.

  • Before you begin to clean your refrigerator, turn the temperature control to OFF so you won't overwork the linear compressor, which is the refrigerator motor.
  • Remove everything from your fridge so you can identify anything that has spoiled or expired. If you don't know how long something has been in there, you'd be better off throwing it out, too.
  • Use a cooler to keep everything you're not throwing out cool while you clean. Don't worry if you don't have a cooler large enough. Improvise by using a large cardboard box with a towel on the bottom and another on top.
  • Remove shelves, baskets and racks. Allow them to warm to room temperature before you start cleaning them, so they don' t crack. Put them all to soak (maybe in your bathtub?) while you clean the rest of the fridge.
  • Wipe down the entire inside of the refrigerator using a dishcloth and a mild solution of warm water and detergent. Remember to clean the door shelves, the rubber seal around the door and where the door seal touches the refrigerator.
  • Use vinegar with a clean cloth for tough stains. Rub in a circular motion. Prefer vinegar to bleach or other chemicals because it's a natural, safe cleaner.
  • Mix about 1/4 cup of baking soda with a half-gallon of warm water and use it to wipe down the inside of the refrigerator, and then rinse and wipe dry. This will help eliminate odors.
  • Remember those shelves and baskets you put to soak? Let's go back to them. Rinse them thoroughly, wipe them dry, and put them all back in the refrigerator, just like you found them.
  • Put all that food back where it belongs, but not before wiping off glass jars and plastic containers with warm water and a dishcloth.
  • Turn your refrigerator temperature control back to the recommended setting and let's clean the exterior.
  • If you have a painted or plastic exterior refrigerator, use a solution of warm water, detergent, and a sponge to clean it. Then use a damp cloth to rinse and a soft cloth to dry it. If you have stainless steel or any other type of metal exterior, use a mineral oil based stainless steel cleaner. Wipe in the direction of the grain.
  • To keep your LG refrigerator looking great, always wipe up spills immediately and seal all food containers
  • Refer to Smart Diagnosis for all error issues.

It's good to check your refrigerator and freezer now and again to make sure they're working just as they should. The temperature may be too warm or too cold, frost or moisture may be building up, or your ice maker may not be producing enough ice. Keep an eye out for small problems to prevent them from getting bigger.
