Refrigerator
A cold cabinet of plastic liners, rubber gaskets and glass shelves, where the manufacturer's longest instruction is a prohibited list and the strangest is about temperature.
What not to do
Mild cream cleanser is unsafe on Refrigerator
Unsafe
Do not do this. The risk is established, and it is described below.

Precautions
- Disconnect from the power supply first
- Check the manufacturer's instructions

What this is, what tends to go wrong with it, and what to do about it.
Made from
Which part are you cleaning?
These parts take different answers. Cleaning one the way you clean another is a common way to damage this.
- Fridge door seal
A folded rubber gasket that traps crumbs and holds moisture — and the one part of a fridge where drying properly is the instruction rather than an afterthought.
Appliance seal rubber
Things not to use here
- Fridge shelf
Toughened glass that has been sitting at four degrees. The manufacturer's instruction is about temperature before it is about cleaner.
Things not to use here
- Crisper drawer
A removable plastic box that holds moisture on purpose. It comes out, and the manufacturer's prohibition list applies to it rather than the general kitchen one.
Household plastics
Things not to use here
- Door liner
The moulded plastic inside face of the door. It is not the same surface as the shelves and it is not the same surface as the stainless outside.
Household plastics
Things not to use here
What tends to go wrong
A living growth, not a stain. Killing it and removing the staining are two separate jobs, and neither addresses the moisture that caused it.
Why it is difficult: Porous and non-porous surfaces, Moisture control and recurrence, Cleaning, sanitising and disinfecting, Organic load, Surface roughness
- Fingerprintsvia its material
Skin oils transferred by touch. A greasy soil rather than a dirty one, which is why water alone does not shift them and why they return immediately.
Why it is difficult: Surfactancy
- Water marksvia its material
What hard water leaves behind when it evaporates instead of being wiped away. A mineral film, not dirt, and the fix is at the drying stage.
Why it is difficult: Water hardness, Evaporative deposition
- Rustvia its material
Hydrated iron oxide from corroding iron or steel. Distinguish a surface deposit, which cleans off, from active corrosion of the item itself, which does not.
Why it is difficult: Corrosion and passivation, Why old stains are harder, Adhesion and cohesion
- Burnt-on food and carbon depositsvia its material
Food heated until it carbonised and bonded to the surface. Time and softening do the work; scouring powder does the damage.
Why it is difficult: Contact time, Carbonisation, Adhesion and cohesion, Why old stains are harder
- Greasevia its material
Fats and oils, which water alone cannot lift. Removed by surfactants, by heat, by solvents, or by alkalis that convert the fat into soap.
Why it is difficult: Why oil resists water, Emulsification
- Heat tintvia its material
The rainbow or brown bloom on stainless steel that has been heated. Not a deposit and not dirt: the metal's own surface oxide, thickened by heat.
- Limescalevia its material
A hard, chalky calcium carbonate deposit left by hard water. Dissolved by acids, essentially untouched by detergents.
Why it is difficult: Water hardness, Crystallisation, Adhesion and cohesion
The science behind this: Corrosion and passivation, Water hardness, Chloride attack, Cleanability is designed in
In detail
A fridge looks like one surface and is at least three, and the manufacturer's guidance treats them separately. The liners and plastic parts, the door gaskets, and the glass shelves each get their own instruction, and only one of those instructions is about a cleaner. The approved routine is unremarkable: warm water with mild dish soap, a soft cloth, everything completely dry before it goes back in. The prohibited list is longer and names its surfaces — abrasive or harsh cleaners, window sprays, scouring cleansers, flammable fluids, cleaning waxes, concentrated detergents, BLEACHES and cleansers containing petroleum products must not be used on plastic parts, interior and door liners, or gaskets. Ammonia-free is specified for appliance sprays, which quietly rules out most glass cleaner. The instruction nobody expects is about the shelves, and it is not chemical. Let glass shelves warm to ROOM TEMPERATURE before washing them, and avoid hot water on cold glass. It also gives THREE intervals rather than one: a WEEKLY wipe-down of shelves, handles and spills, a deep clean every ONE TO THREE MONTHS, and a MONTHLY gasket check. Spills are the exception, and are wiped up IMMEDIATELY.
What works
Detergent is safe on, in specific conditions, Refrigerator
Safe only in specific conditions
This is only appropriate within specific limits. Outside those limits, no claim is made.
Only within these limits:
- MILD dish soap in warm water - concentrated detergents are on the prohibited list
- a soft microfibre cloth or non-scratch sponge
- glass shelves brought to room temperature first, because hot water on cold glass causes thermal stress
- everything completely dry before it is put back
Precautions
- Disconnect from the power supply first
- Check the manufacturer's instructions

Relied on for: That warm water with mild dish soap on a soft microfibre cloth is the approved solution, that concentrated detergents are prohibited, that glass shelves must warm to room temperature before washing, and that all parts must be completely dry before reinstalling. (states this directly)
Acetic acid (vinegar) is safe on, in specific conditions, Refrigerator
Safe only in specific conditions
This is only appropriate within specific limits. Outside those limits, no claim is made.
Only within these limits:
- White vinegar diluted one part to one part water
- For deodorising
- Rinse afterwards
- Not on plastic parts, liners or gaskets with anything stronger — bleaches and concentrated detergents are prohibited there
Vinegar is rarely cleared on an appliance, and here it is cleared for odour rather than for cleaning.
Precautions
- Rinse thoroughly afterwards
- Check the manufacturer's instructions
