Soap, Oil or Lacquer: What Your Oak Finish Actually Does

Oiled oak asks for very little: a dry cotton cloth most weeks, a damp cloth and mild soap when it's actually dirty, and a fresh coat of oil only once the surface starts looking pale or dry rather than on any fixed schedule. That is the entire regime Form & Refine specifies for its own oak furniture, and it is a lighter routine than the word "maintenance" tends to imply — the finish is built to be topped up at home, not stripped and redone by a professional.

What an oil finish actually is

Form & Refine's oak pieces, including the Shoemaker Chair™ no. 68 and the Position Bench 155, are specified simply as "Finish: Natural Oil" on the house's own product pages. Oil doesn't sit on the wood as a film the way lacquer does; it soaks into the surface fibres and leaves the grain, colour and slightly open texture of the oak visible and touchable. That is the whole design argument for choosing it over a harder coating — the wood keeps reading as wood, and the finish can be renewed in place rather than sanded back and reapplied in a workshop.

The weekly routine, from the house itself

Form & Refine's published care instructions are specific rather than generic. For daily cleaning: "use a clean, dry cloth, ideally a cotton cloth," and avoid "scouring pads or synthetic cloths" that can scratch the surface. For actual dirt, the guidance moves to "a damp cotton cloth firmly wrung in clean water" before anything stronger is considered, and mild, solvent-free soap is the ceiling — "harsh or abrasive cleaning agents" are ruled out because they don't clean around the oil, they strip it. None of this is unusual advice for wood in general; what matters is that it's the house's own instruction for its own finish, not a generic furniture-care leaflet.

When to reoil, and with what

Form & Refine sells matched Maintenance Kits — Natural Oil and White Oil, each 100 ml — rather than one universal product, because reoiling with the wrong variant is the easiest way to change a piece's tone by accident. There's no printed interval; the practical signal is the surface itself; oak that has dulled or lost its slight sheen, or that no longer beads a drop of water, is due for a fresh coat. This is closer to how a leather item is kept than how a lacquered table is polished — small, occasional attention rather than a seasonal ritual.

Soap, lacquer and the other ways oak gets finished

Oil is one of several traditional ways to treat oak, not the only one. Carl Hansen & Søn, the Danish house that finishes its own oak across the full range, lists oil, soap, white oil, lacquer and smoked oil as its standard surface treatments — and notes that because of oak's open cell structure, "the wood structure is visible under the paint" whichever finish is chosen. Soap is the closest relative to oil: an age-old Scandinavian treatment that, per Danish wood-care specialist WOCA, needs weekly applications for roughly the first three months to build up in the grain before dropping to occasional maintenance, and it leaves oak looking close to its raw, untreated colour. Lacquer sits at the other end — a sealed, harder shell that resists marks and spills more readily but can't be topped up the way oil or soap can; once it's worn through, the whole surface has to be stripped back and recoated. None of the three is objectively "better" — they're a trade between how little upkeep a piece asks for early on and how much control the owner keeps over its surface for the next twenty years.

For an Objena order, that trade is already made — Form & Refine's oiled oak, on pieces like the Shoemaker Chair™ no. 68 (AUD 1,490) and the Position Bench 155 (AUD 1,650), asks for a cloth, occasionally soap, and eventually a small bottle of oil, not a professional refinish. The house's wider approach to material and origin runs through the Form & Refine chapter.

Three questions

How do you care for oiled oak furniture day to day? Form & Refine's own instructions are simple — a clean, dry cotton cloth for regular dusting, avoiding scouring pads or synthetic cloths that can scratch the surface. For dirt, use a cotton cloth dampened and firmly wrung out in clean water, and only reach for a solvent-free, mild soap if that isn't enough. Harsh or abrasive cleaning agents are ruled out entirely, because they strip the oil rather than clean around it.

How often does oiled oak need reoiling, and with what? There's no fixed calendar date — reoil when the surface looks dry or pale rather than on a schedule — but Form & Refine sells matched Maintenance Kits in Natural Oil and White Oil (100 ml) so the reapplied oil follows the piece's original finish rather than a generic substitute. Using the wrong oil variant is the main way an otherwise careful owner changes the tone of a piece by accident.

What's the actual difference between an oiled, soaped and lacquered oak finish? Carl Hansen & Søn, which finishes oak across all five methods, treats oil and soap as finishes that keep the grain and pale tone visible and can be refreshed at home, while lacquer builds a harder, more sealed surface that resists marking but has to be stripped and reapplied rather than simply topped up. Oak's open-cell grain stays visible under any of them; what changes is how much of the wood is still breathing under the surface, and how much work falls to the owner over the years the piece is in a room.
