Three finishes, three routines
Oil-finished pieces (most seating, tables) — re-oil once or twice a year with raw linseed oil or tung oil. Wipe on with a cloth, let it sit fifteen minutes, then wipe off the excess. The whole job takes about twenty minutes per piece and the oil dries overnight.
Wax-finished pieces (shelving, cabinets) — apply a thin coat of natural beeswax polish every twelve to eighteen months. Buff with a dry cloth once the wax has hazed over, usually after ten minutes.
Raw ebony pieces — left unfinished by design. No oil or wax needed; simply dust and avoid prolonged direct sun, which can lighten the surface over years.
