Care and maintenance.
I finish every piece with hand-rubbed oil, which behaves differently from the sprayed lacquer or polyurethane on factory furniture. Sprayed finishes sit on top of the wood as a plastic film; oil cures inside the wood and stays part of it. That means less maintenance, but the maintenance it does need is a real habit, not a periodic refinish. What follows is exactly what I do to my own pieces.
White oak · Janka 1360
Caring for white oak.
Sourced from Catskills, NY
- Daily
- Dust with a dry microfiber cloth. Cup rings show up under drinks, so keep coasters within reach the first week a piece is in the room. Sunlight is fine on white oak, it yellows less than most.
- Monthly
- Soft cloth with a tiny amount of pure carnauba wax on wear surfaces: table edges, chair arms, the front lip of a drawer. Wipe with the grain, then buff. A small tin lasts years.
- Yearly
- Full oil coat. Osmo Polyx-Oil satin, thin coat with a lint-free rag, buff after twenty minutes. That's the whole job.
- What to avoid
- Silicone-based polishes like Pledge, water glasses without a coaster, and a lit candle sitting in the same spot on the tabletop for hours at a time.
Walnut · Janka 1010
Caring for walnut.
Sourced from Central Pennsylvania
- Daily
- Same dry-cloth dusting. Walnut oxidizes toward gold over time, so don't leave a runner or a stack of books on the same spot for months on end. You'll get patchy fading where the light couldn't reach.
- Monthly
- Same wax pass as oak. Small amount of carnauba on the wear surfaces, wipe with the grain, buff.
- Yearly
- Osmo Polyx-Oil (raw, for walnut). It's a special formula that doesn't add an amber tint. One thin coat, buffed.
- What to avoid
- Strong light for twelve or more hours a day if the piece is stationary, acidic cleaners like vinegar dilutions, and sudden temperature swings. A room that goes from 60F to 80F within an hour will crack a slab top.
Cherry · Janka 950
Caring for cherry.
Sourced from Central Pennsylvania
- Daily
- Same dust routine. Cherry patinas the fastest of the three, and direct sun darkens cherry, which is the opposite of walnut. Rotate table centerpieces and lamps once a month so it patinas evenly.
- Monthly
- Wax as above. Cherry seems to take wax better than the other two, and the surface comes up with a warm sheen after buffing.
- Yearly
- Tried and True Original Wood Finish (linseed oil plus beeswax, food-safe). Two thin coats, twenty-four hours between them.
- What to avoid
- Putting a piece in a dim corner for a year. It'll be noticeably lighter than the sun-exposed side and take a decade to catch up.
All woods · General guidance
For every wood in the shop.
- Daily
- Humidity is the one variable that matters more than any finish. 40 to 55 percent RH is the sweet spot. A room humidifier in winter (once you drop below 30) prevents cupping and end-grain checking. A dehumidifier in summer helps stability.
- Monthly
- Look at the joints. Any gap that wasn't there last month is telling you something about the room. That's usually humidity, not the joinery, but it's worth an email.
- Yearly
- Walk each piece once a year: check that leveler feet are still snug, that drawer runners haven't dried out, that a stretcher isn't loose. Five minutes per piece.
- What to avoid
- Dragging a piece across the floor. Lift it. Tabletops carry weight down to the aprons through the mortises, and dragging by a corner puts a lever on joints that were never designed to take one.
After delivery
If something needs attention
I'll take a look.
I'm 90 minutes north of Manhattan and happy to look at any piece I've built. No charge for advice, minimal for hand-repair, and I'd always rather see a piece back on the bench than see it retired.
