Cleaning the inside of a refrigerator is a food safety job, not a cosmetic one. A fridge that smells is a fridge growing bacteria on its shelves, and a spill left for a month becomes a stain that never comes out. Empty it, wash it, dry it — the whole job takes 30 minutes, and a clean fridge keeps food safe longer.
Baking soda and warm water is the cleaner: one tablespoon per quart. It cuts grease, kills odors, and does not leave a chemical taste on food — unlike bleach or strong detergents, which you should never use inside a fridge. A fridge that smells needs the source out first: the smell is usually one forgotten container at the back.
Empty it completely. Take everything out: shelves, drawers, and food. Put the perishables in a cooler with ice — a fridge left open for 30 minutes warms up, and warm food grows bacteria. Throw out anything expired or anything you cannot identify.
Take the shelves and drawers out. Take the shelves and drawers out and wash them in the sink with hot soapy water. Let cold glass shelves warm to room temperature first — hot water on a cold glass shelf cracks it. Dry them completely before they go back.
Wipe the inside. Wipe the inside walls, floor, and door gasket with baking soda and warm water. Pay attention to the door gasket: crumbs and mold collect in the folds, and a dirty gasket does not seal — a fridge that does not seal runs all the time. The fridge runs all the time guide covers the 6 causes, from dusty coils to a tired compressor.
Clean the spills and the stains. Scrub the spills and the stains: baking soda paste for dried spills, a plastic scraper for the stubborn ones. Never use a metal scraper or an abrasive pad inside a fridge — they scratch the plastic and the scratches hold bacteria forever.
Dry everything before it goes back. Dry the inside, the shelves, and the drawers completely before anything goes back. A wet shelf grows mold in a week; a dry shelf does not. Put the food back in order: the oldest in front, the newest at the back.
Clean the coils while you are at it. Clean the coils while the fridge is empty: pull the fridge out, vacuum the coils, and brush off the dust. Dirty coils are the most common reason a fridge stops cooling — the refrigerator coil cleaning guide covers 20 minutes twice a year, and the not cold enough guide covers the 7 checks before you call repair.
Deep clean every 3 months, wipe spills the day they happen. A spill left for a week becomes a stain; a spill left for a month becomes a smell. The door gasket needs a wipe every month — a gasket that does not seal costs electricity every day.
Never use bleach or strong detergents inside the fridge — they leave a chemical taste on food and the fumes stay in a closed box. Never put hot glass shelves under hot water — they crack. Never use a metal scraper on the plastic interior. And never leave the fridge door open while you clean: the compressor runs the whole time and the food warms up.
Deep clean every 3 months, wipe spills the day they happen. A spill left for a week becomes a stain; left for a month, a smell.

Usually the door gasket or one forgotten container. Crumbs and mold collect in the gasket folds — wipe them. And check the back of every shelf: the smell is usually one container you forgot.
Yes, diluted — but baking soda is better: vinegar leaves a smell that stays in a closed fridge, and it does not cut grease as well. Never mix vinegar with bleach.
