Summary
The soft strip around the edge of a fridge door is the only thing standing between your food and the room. It collects crumbs, spilled milk and a film of grease, and in the fold behind its lip that mixture goes black. A dirty seal is not just unpleasant to look at: dirt on the sealing face holds the door open a fraction, and a fridge that is running against a permanent air leak works harder and stays warmer than the dial claims. The job takes about half an hour and needs a cloth, a bowl and nothing else.
What this page will not do is tell you what to put on the rubber, and that sounds like a dodge but is not. GE Appliances tells you to wipe the gasket with warm water and baking soda and says in the same breath not to use anything containing detergent. Whirlpool tells you to clean the gasket with a damp cloth and mild soap. LG tells you to use a sponge or a toothbrush with detergent, and Samsung tells you to use dish soap. Three of the four prescribe the thing the fourth prohibits, so the answer is written in your own manual and nowhere else. Everything else here — the fold, the paper test, the drying — is the same on every machine.

READ THE CARE INSTRUCTIONS FOR YOUR MODEL BEFORE YOU PUT A CLEANER ON THE DOOR SEAL.
GE Appliances says that a product with detergent in it can cause damage to the gasket. Whirlpool gives a mild soap for the same part.
- Read the care instructions in the documentation for your model.3mReport a problem with step 1, Prepare the refrigerator and the cleaner
- The four manufacturers on this page do not agree about the correct cleaner.
- The specifications on this page give the disagreement in full.
MOVE THE FOOD FROM THE DOOR SHELVES TO A COOL PLACE BEFORE YOU CLEAN THE SEAL.
The FDA says that food above 40 °F for more than 2 hours is not safe. Bacteria in warm food can make you ill.

DO NOT USE A FLAMMABLE FLUID ON THE DOOR SEAL.
Whirlpool prohibits a flammable fluid on this part. A flammable fluid near an appliance can catch fire.
USE ONE CLEANER ONLY.
The CDC says that you must never mix bleach with a different cleaner. A mixture of bleach and a different cleaner can make a toxic gas.

Terminology
This page uses one term for each item and holds it throughout, as ASD-STE100 requires. Equipment sellers and other guides use the names below for the same parts.
- door seal
- Also called: door gasket, fridge gasket, fridge seal, refrigerator gasket, rubber seal, rubber strip, the rubber bit round the fridge door, freezer seal, magnetic seal
- refrigerator
- Also called: fridge, icebox, fridge freezer, fridge-freezer, refrigerator freezer, the fridge
- mold
- Also called: mould, mildew, black mold, black spots, black speckles, gunk, slime
- paper test
- Also called: dollar bill test, dollar test, note test, paper towel test, seal test
- cabinet
- Also called: fridge body, the frame, the case, the box
When to use a professional
Stop if the door seal has a tear, a hole or a cut. Warm air goes into the cabinet through a tear in the seal. This procedure does not repair it. Speak to an appliance technician or to the manufacturer about a new seal.
Stop if a section of the seal is out of its channel. Do not pull the seal off the door. The seal must be in one exact position on the door.
Stop if the paper test fails after a second clean. The cause is then the position of the door, the hinges or the seal. This procedure does not adjust a door or a hinge. Samsung says that a new refrigerator can fail this test. The cause is then the position of the doors.
Stop if you see water or ice on the inside face of the door after each clean. A door that collects ice has a fault that is not dirt.
Common questions
What can I actually use to clean a fridge door seal?
Whatever your own manual says, and this is the one thing on the page we refuse to decide for you. GE Appliances prescribes a quart of warm water with a tablespoon of baking soda and explicitly rules out anything containing detergent, bleach, ammonia or petroleum distillates. Whirlpool prescribes a damp cloth and mild soap. LG prescribes a sponge or toothbrush with detergent after a hot steamed towel, and Samsung prescribes dish soap on a damp cloth. Three of the four tell you to use the class of product the fourth says will damage its gaskets. If you own a GE, warm water and baking soda; if you own anything else, look it up before you reach for the washing-up liquid.
Is the dollar bill test on a fridge door a real test?
Yes, and it comes from the manufacturers rather than from folklore. Samsung publishes it directly: put a piece of paper halfway into the door, close the door on it, and pull. Slight resistance means the seal is still working; paper that slides straight out means it is not. Do it at the top, the bottom and both sides, because a seal can be sound in one place and dead in another. Samsung also notes that a brand-new fridge can fail the test simply because the doors are not aligned yet, so a failure on a recent installation is a door alignment question rather than a gasket question.
Should I rub Vaseline on the fridge seal to keep it soft?
Not on the strength of anything we could verify, and one manufacturer contradicts it outright. GE Appliances does name a lubricant for gaskets, but it is pure paraffin wax, not candle wax — and reserves pure petroleum jelly for the door hinges, which are a different part. Whirlpool prohibits cleansers containing petroleum products on gaskets altogether. Two makers, two positions, and neither one is a statement about your machine unless you own that machine. Clean the seal, dry it, and leave the jar in the cupboard until your own manual names something.
Why does the black mould keep coming back on my fridge seal?
Because it lives in the fold behind the lip of the gasket, not on the face you can see, and wiping the face never reaches it. That fold catches crumbs, spilled milk and condensation, and it stays damp. Lift the lip with your fingers, clean inside it, and — this is the step people skip — dry it properly afterwards. Whirlpool's own instruction is to lift the folds, remove the crumbs and dry fully. Staining that has been there for months sometimes will not come out at all, because the pigment has soaked into the rubber; the seal is still sound, it just looks bad.
How often should I clean the fridge door seal?
Whirlpool and Samsung both land on monthly — Whirlpool lists a gasket check monthly to remove debris and keep a tight seal, and Samsung says to clean the seals once per month with a damp cloth and dish soap. GE describes the job without naming a frequency. Monthly is a sensible working answer, but check your own manual, and do it straight away if you can see staining or the door does not pull shut with the usual tug.
Does a dirty fridge seal really cost me money?
It costs you cold, which is the same thing. Whirlpool's own troubleshooting for doors that will not seal starts with the gasket: dirt and other particles build up on the gasket surface and cause resistance, which holds the door fractionally open. The compressor then runs longer to hold the same temperature, and the compartment sits warmer than the setting says. We are not going to put a percentage on it, because no manufacturer or government source we opened publishes one for a dirty gasket, and a number nobody stands behind is worse than no number.
Can I take the seal off to wash it in the sink?
No. The gasket sits in a channel around the door and is often held by the door liner or by a retaining strip, and it has to go back in exactly one position or the door will never seal again. Clean it in place. If a section has come out of its channel, press it gently back in; if it will not stay, that is a job for the manufacturer or an appliance technician, not for you and a screwdriver.

The cleaning agent and the gasket lubricant both publish as consult-the-manufacturer with conflict notes: GE prohibits detergent on its gaskets while Whirlpool, LG and Samsung all prescribe a soap or a detergent for the same part. Source entries are staged in data/sources-additions-clean-a-refrigerator-door-seal.json for merge into data/sources.json by an authorized actor; the record holds on checks 2 and 3 until that merge happens.
