Fridge shelf
Toughened glass that has been sitting at four degrees. The manufacturer's instruction is about temperature before it is about cleaner.
What not to do
Water is unsafe on Fridge shelf
Unsafe
Do not do this. The risk is established, and it is described below.
Warm water on a COLD glass shelf. The shelf can break, and tempered glass breaks into pebbles all at once.

What this is, what tends to go wrong with it, and what to do about it.
The science behind this: Thermal shock
Part of Refrigerator.
In detail
A fridge shelf is glass, and it has been cold for as long as the fridge has been on. That is the whole instruction: let glass shelves warm to ROOM TEMPERATURE before washing them, and avoid hot water on cold glass, because the temperature difference puts the pane under thermal stress. It is the same mechanism described for a wood-burning stove door, running in the opposite direction — there the glass is hot and the water is cold. Either way it is a differential across a thickness of glass, and glass fails suddenly rather than gradually. Once it has warmed, a shelf is ordinary: warm water with mild dish soap, a soft microfibre cloth or non-scratch sponge, and thoroughly dry before it goes back in. What must not touch it is the same prohibited list as the liners — no abrasives, no scouring cleansers, no bleach, no window spray, nothing containing ammonia or petroleum. The practical version: take the shelf out, stand it on a towel until it stops feeling cold, then wash it. The FAQ adds that glass shelves and bins ARE dishwasher safe, while recommending handwashing — a permission and a preference, not a contradiction. The room-temperature rule survives both.
What works
Soap is safe on, in specific conditions, Fridge shelf
Safe only in specific conditions
This is only appropriate within specific limits. Outside those limits, no claim is made.
Only within these limits:
- Let the shelf reach ROOM TEMPERATURE first — this is the whole safety condition
- Then warm, soapy water
- Dry thoroughly with a microfibre or soft cloth before re-installing
- Both hands when lifting; the glass is heavy and impact breaks it too
The ordering carries the risk. The identical method is correct after warming and dangerous before, which is not something any object-level answer about a fridge would tell you.

Why
- Fridge shelf is explained by Thermal shock
Thermal shock is the same mechanism described for stove glass, running the other way: there the glass is hot and the water cold, here the glass is cold and the water hot.
