Mattress
The manufacturer's answer is that you largely do not clean it. You protect it, vacuum it, wash the cover — and above all keep it dry.
What not to do
Unsafe
Do not do this. The risk is established, and it is described below.
Why we say this
Strongly supported
A blunt manufacturer prohibition rather than an inference, and the reason the whole family diverges from upholstery. Recorded against water because wetting is the named hazard, not any particular product.

- Test on an inconspicuous area first
- Ventilate the area
In detail
Almost everything written about cleaning a mattress treats it as upholstery you cannot lift. Two credible bodies disagree about the treatment and agree about the constraint. THE MANUFACTURER'S POSITION IS THAT A MATTRESS IS PROTECTED RATHER THAN CLEANED. It leads with a prohibition — mattresses should never get wet — and grants stain treatment grudgingly: IF YOU MUST, mild soap with COLD water, applied lightly. Dry-cleaning fluid of any type is excluded on any mattress. Routine care is vacuuming and washing the COVER. THE BED TRADE ASSOCIATION IS MORE WILLING, AND ITS FIRST INSTRUCTION IS THE ONE READERS SKIP: strip the bedding and STAND THE MATTRESS ON ITS SIDE, because gravity decides whether a spill reaches the filling. Then sponge immediately with cold water, without over-wetting. Urine takes a WARM detergent or upholstery-shampoo solution, then cold water with a few drops of antiseptic; VOMIT IS ROUTED RATHER THAN OMITTED — lift the solids without spreading, then treat as urine. Oily marks take an AEROSOL grease solvent, cautiously on foam. Warm against cold, and a solvent against a class prohibition: published as a conflict, not averaged. Neither addresses YELLOWING.

Where the sources disagree
A mattress has been stained. Cold water and mild soap only, or the trade body's warm detergent and solvent?
Part of this is scope and part of it is not. THE SOLVENT DIFFERENCE IS PARTLY SCOPE. The manufacturer writes for a range in which foam is usual, and foam has least tolerance for a solvent and no way to flush one out. The trade association writes across UK beds including sprung ones, and it does not ignore the problem — it attaches 'cautiously on foam' to the same instruction. The more foam is present, the closer its advice moves to the prohibition. THE TEMPERATURE DIFFERENCE IS NOT SCOPE. Warm and cold are not two readings of one instruction; they are opposite answers about the same sponge on the same stain, and no construction difference explains it. It is left standing. What neither disputes is the more useful part: act immediately, do not over-wet, and get the liquid out of the mattress's path first. Standing the mattress on its side is the only step in either document that changes the outcome rather than the appearance, and the manufacturer contradicts nothing in it.
What to do: Do the two things both bodies support first, because they are the ones that matter: strip the bedding and stand the mattress on its side so the spill stops travelling, then lift what you can with cold water and no flooding. After that, let the construction decide. On a foam or foam-topped mattress take the manufacturer's line — cold, mild soap, light, and no solvent at all. On a sprung mattress the trade association's warm detergent procedure is a credible body's published instruction and is available to you. Whichever you use, the limit is the same: what has soaked below the surface is not reachable by anything applied to the surface, which is why both documents end up recommending a protector rather than a technique.

Relied on for: That the bedding is stripped and the mattress stood on its side to stop liquid reaching the filling; that urine takes a warm solution of mild detergent or upholstery shampoo then cold water plus a few drops of antiseptic; that vomit and diarrhoea are treated as urine once solids are lifted; and that oily marks take an aerosol rather than liquid grease solvent, cautiously on foam. (states this directly)

Read on — The two sections the page is built from: the general instruction that opens it, and the stain-by-stain table — urine, red wine, fruit juice, chocolate and milk drinks, blood, oily marks, and vomit or diarrhoea. Supports the claim as stated. Covers vomit-on-a-mattress, which is named outright, and urine-smell-in-a-mattress, where the trade body's procedure plus this register's existing depth model of urine odour make a complete answer. It also puts this body in DIRECT CONFLICT with the mattress manufacturer already held: warm water against cold, and an aerosol grease solvent against a prohibition on dry-cleaning fluid of any type on any mattress. That conflict is recorded rather than resolved by preference. Yellow marks stay partial, now with a stated reason instead of no note at all.
