Wooden furniture
The finish decides everything, and the most-used product on it leaves a residue that survives stripping the finish down to bare wood.
What not to do
Furniture polish should be avoided for Wooden furniture
Best avoided
The available guidance advises against this.
The cost is paid only if the piece is ever refinished — and it is paid then whatever is done in the meantime.
Precautions
- Test on an inconspicuous area first
- Check the manufacturer's instructions

What this is, what tends to go wrong with it, and what to do about it.
Made from
Finished wood flooring, Waxed wood, Oiled wood, Lacquered metal
What tends to go wrong
Mostly textile fibres and skin, held by static as much as by gravity — which is why a dry cloth on a plastic surface makes it worse.
Why it is difficult: Static and dust, Mechanical action and abrasion, Why different surfaces get different dirt, Surface roughness
Left by most furniture polishes, invisible, and present even after a finish has been stripped to bare wood. It is discovered on the day somebody tries to refinish.
Why it is difficult: Water-repellent and water-attracting surfaces, Coating thickness
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
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
- Mould fungivia its material
The organisms behind the marking. Around 1.5 million species, each with its own conditions — and killing them does not end the exposure they created.
Why it is difficult: Organic load, Moisture control and recurrence, Biofilm
- Mudvia its material
The one stain where the first move is mechanical and the chemistry barely matters — and where the folk advice to let it dry first is not what the trade body says.
- Tarnishvia its material
Unlike a stain, tarnish is made of the very surface it sits on. Removing it always removes metal.
Why it is difficult: Coating thickness
- 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
The science behind this: Material compatibility, Fibre swelling and shrinkage, Soap versus detergent, Residue and resoiling, Thermal shock, Solubility and polarity
In detail
Almost every question about cleaning wooden furniture is a question about its finish rather than its timber. The wood flooring trade gives a similar rule for floors: use a cleaner made specifically for the finish. The most consequential finding is about the product most people reach for. A federal conservation leaflet states that the majority of commercial furniture polishes contain silicone, that it is found in almost all liquid and aerosol wax preparations, and that once applied it can be difficult to remove — then goes further: a silicone residue can be present even when the old finish is stripped down to the bare wood. The consequence surfaces years later, when a new finish is applied and small crater-like indentations called fish eyes appear. For a piece that might one day be restored, it is a decision made now with the evidence arriving decades later.
