Why your care page shouldn't say 'every six months'.

The care instruction that fails most often is the calendar-driven one. Polish every six months. Wax twice a year. Re-oil in spring. These instructions sound reasonable, and they are the kind of instruction a maker is tempted to write because the maker knows the material. But the calendar is not what the material is responding to. The material is responding to use, light, humidity, and touch.

This piece is intended as a draft of what I would rather write on every care card that leaves my shop. The cadence is shorthand. The instruction should be longer.

Oil-finished walnut

Oil finished walnut — hand-rubbed, three coats over a sealed grain filler — does not need to be re-oiled on a calendar. It needs to be re-oiled when the surface stops taking fingerprints. If your fingertip slides across the top and the grain goes uniformly matte, the finish is intact. If you can see the path of your finger against the light, or the surface feels dry in patches, the finish is thinning. Re-oil then. Anywhere from eighteen months to five years is the natural range.

Material responds to use, light, humidity, and touch. Not to the calendar.

Oiled steel

Oiled steel — blackened or waxed — does not need a twice-a-year wax. It needs wax on the places where the wax has rubbed off. The places where the wax has rubbed off are the places where the owner has touched it: the corners of a handrail, the working edge of a fireplace tool, the rim of a coal scuttle. Those are the places to re-wax first. If the whole piece has gone dry at once, something has changed — the room is drier, the piece has moved outside, the wax was stripped by a cleaner — and it is time to wax everything.

Bronze with a living finish

Bronze with a living patina — a moulded or patinated finish that is meant to age with the piece — is finished by leaving it alone. Stripping a patinated bronze is destructive. The owner of a patinated bronze should not buy polish. They should buy a soft cloth and they should use it on the dust. They should ignore anything they have read online about bringing the shine back.

Hardwood lumber forks

Hardwood with a wax or oil finish (the kind of finish that a traditional hickory, cherry, or ash farm implement might carry) does not need a yearly oiling when it is in regular use. The oil comes off on the user's hands and onto the piece. A piece that has gone two years without a hand on the handle has gone dry and should be re-oiled. A piece that is being used has not.

Porcelain enamel

Porcelain enamel needs almost nothing. A soft cloth. Soap if it has gotten greasy. No abrasives. No polish. No baking soda. The owners who damage porcelain enamel are almost always trying to get a stain out of it. The stain would have come out of a porcelain basin; porcelain enamel is not porcelain. If the finish has held for ninety years, the right answer is to leave it alone.

Hand-rubbed varnish

Hand-rubbed varnish — the kind of finish that goes on a Halverson table or a mid-century walnut hutch — does not need polish. It needs a soft cloth and the application of furniture wax only when the surface has begun to feel sticky under a warm hand. The wax is a sacrificial layer meant to keep hands and dishes off the varnish. Polishing the wax away is exactly the wrong thing to do.

What the care page should have

Instead of a calendar, write the care card with three questions on it. What does this finish respond to? What does the owner do that wears this finish? What is the early sign that the finish is wearing? Three questions, three answers, and the owner has a care rhythm for the next decade or two. They will not need to come back to your shop with a stained top. They will repair the finish at home because the care card told them how the finish fails.

Five-and-a-half years is not the answer. The answer is, the finish goes matte where you put your fingertips. When it does, this is the oil. When the wood starts to feel thirsty, this is the wax. That is the care card.
