How to care for solid wood furniture, for the next 30 years

Solid wood furniture doesn't wear out the way particleboard does — it ages. Left alone with a bit of light and use, oak and walnut both deepen in color over the first few years, developing a patina that veneer simply can't replicate. But that aging process only goes well if you give the wood a little help along the way.

Keep it out of direct sun where you can. UV light is the single biggest cause of uneven fading — a rug or a plant moved every few months does more for a tabletop's color than any polish. Humidity matters almost as much: wood expands and contracts with moisture in the air, so a consistent indoor climate (whatever it is) will always beat wild seasonal swings for keeping joints tight.

For day-to-day care, a dry or barely-damp cloth is almost always enough. Avoid silicone-based sprays, which build up a film over time and are a nightmare to strip later. Every six months or so, a small amount of food-safe mineral oil rubbed into any exposed end-grain will keep it from drying out and cracking — this matters most on cutting boards and butcher-block surfaces, less on a finished dining table.

Scratches happen, and on solid wood they're almost always fixable. A light scuff can often be buffed out with a matching wood wax; deeper scratches can be sanded and re-oiled by hand without needing to refinish the whole piece — one more reason solid wood tends to outlast everything else in the room.
