How to Care for Black Walnut Furniture

Black walnut is a deep-toned, beautifully figured and durable hardwood, and with the right care it only gets better with age. Here are the essentials. If your piece came with its own care instructions, follow those first.

First: hardwax oil or lacquer?

Solid wood furniture usually has one of two finishes, and they're cared for differently:

• Hardwax oil soaks into the wood, so you can feel the grain and it looks natural. Yeswood's premium black walnut collections use a plant-based hardwax oil made from ingredients such as linseed oil and carnauba wax. Worn spots can be refreshed with more oil, but it's less forgiving than lacquer if water or grease sits on it.
• Lacquer forms a protective film on top. It resists water better and is easy to wipe, but scratches are harder to repair locally.

Everyday cleaning

• Wipe along the grain with a soft, well-wrung cotton cloth, then dry with a clean one.
• Don't leave a wet cloth on the surface or let water sit.
• Avoid cleaners with alcohol, ammonia, strong alkalis or abrasives, and skip steel wool and stiff brushes. Damage from unsuitable cleaning products isn't covered by warranty.
• Wipe up spilled water, tea, coffee or oil promptly.

Placement: keep it away from heat, sun, damp and dryness

Solid wood expands and contracts slightly with humidity; that's natural. These conditions make it worse and aren't covered by warranty: excessive moisture or standing water, extreme dryness, direct heat sources and prolonged direct sunlight.

• Keep pieces away from radiators, fireplaces, floor vents and direct air-conditioning airflow.
• Avoid strong sun on the same spot for long periods, which causes uneven color.
• Especially in North American winters: indoor heating makes the air very dry. A humidifier that keeps indoor humidity moderate (40–60% is a common recommendation) reduces the risk of cracks and widening gaps.
• Ventilate damp spots such as near bathroom doors or windows.

Preventing heat marks, water rings and scratches

• Never put hot pans or mugs directly on the surface; use trivets and coasters.
• Condensation from cold drinks leaves white rings too, so use coasters.
• Put saucers under plant pots and vases.
• Add felt pads under chair and table legs and anything you move often, and lift furniture instead of dragging it.
• Use a desk pad when writing or crafting to avoid dents and scratches.

Re-oiling a hardwax oil finish

General guidance for oiled furniture:

• Re-oil when the surface feels dry, looks paler, or water no longer beads. For busy tabletops that's typically every 6–12 months; less-used pieces can go longer.
• Clean and fully dry the surface, apply a thin coat of hardwax oil along the grain with a soft cloth, wait briefly, wipe off the excess, and let it cure for the time the product recommends before use.
• Use an oil compatible with the original finish; ask us if you're unsure.
• Lay oily rags flat to dry or soak them in water before disposal; bunched-up oily rags can self-ignite.
• Light scratches and white rings often improve with gentle sanding along the grain using fine sandpaper, then re-oiling. For deeper damage, contact us first rather than arranging outside repairs.

What's normal, and when to contact us

Natural grain, knots, color variation, mineral streaks and reasonable seasonal movement are characteristics of solid wood. Black walnut also mellows slightly in color with light over time.
