Timber furniture is a classic choice for many Australian homes, whether you live in a breezy Sydney apartment, a Melbourne terrace, or a spacious Queenslander. Solid wood has a natural warmth that other materials simply can’t match. But like anything natural, timber needs care to stay in good shape.

One of the most common questions homeowners ask is: Should I oil my wooden furniture? The answer isn’t always straightforward. It depends on the type of timber, the finish on the surface, and even where you live in Australia. This guide will walk you through whether oiling is necessary, which pieces benefit most, how often you should do it, and the right way to apply oil so your furniture looks good for years to come.

Do All Wooden Furniture Pieces Need Oil?

Not every piece of timber furniture needs regular oiling. The purpose of oiling is to nourish the wood, restore its natural oils, and prevent it from drying out. Oiling also enhances the grain, bringing out the rich character of the timber.

When oiling is important:

  • Furniture made from solid, untreated timber.
  • Pieces finished with natural oils or waxes.
  • Outdoor furniture that’s exposed to sunlight and moisture.

When oiling isn’t necessary:

  • Furniture coated with varnish, polyurethane, or lacquer. These create a sealed surface, so oil won’t penetrate the timber.
  • Painted furniture.

A simple test is to rub a drop of water on the surface. If the water beads, the timber is sealed. If it soaks in, it’s a good sign your furniture could use some oil.

Which Furniture Benefits Most from Oiling?

Some pieces of furniture handle daily wear and tear more than others, making oiling especially beneficial:

  • Dining tables and coffee tables – These get the most contact with food, drinks, and cleaning products. Oiling keeps them looking fresh and resistant to stains.
  • Desks and bookshelves – Exposure to sunlight near windows can dry out the timber; a coat of oil helps prevent fading and cracking.
  • Outdoor settings – Aussie backyards are brutal on timber. Outdoor chairs, benches, and tables should be oiled regularly with exterior-grade oils.
  • Bedroom suites and bed frames – These don’t see as much daily wear, but occasional oiling maintains their warm look.

When Should You Oil Timber Furniture?

Timing is everything when it comes to furniture care.
  • After purchasing bare timber furniture: Most solid timber pieces come pre-finished, but if yours doesn’t, applying oil early on is crucial.
  • At the change of seasons: In Australia, the switch between hot, dry summers and cooler, damper winters can affect wood movement. Oiling at these times helps stabilise moisture levels.
  • When you notice signs of dryness: If the surface feels rough, dull, or looks pale, it’s time to reach for the oil.

How Often Should You Oil Wooden Furniture?

The frequency of oiling depends on your environment and the type of furniture:
  • Indoor furniture: Every 6–12 months is ideal for most dining tables, desks, and shelving.
  • Outdoor furniture: Every 3–6 months, depending on exposure. The harsh Aussie sun, salty coastal air, and heavy rain can wear down protective layers faster.
  • High-use surfaces: Like dining tables, may need attention a little more often than decorative pieces.

Tip: If you’re in coastal Sydney or Brisbane, you may need to oil more often than someone in cooler Hobart or Adelaide due to higher humidity and salty air.

Best Oils for Timber Furniture

Not all oils are created equal. Choosing the right one makes a big difference in results.
  • Linseed oil: A traditional choice that penetrates deeply but can take a long time to dry.
  • Tung oil: Durable and water-resistant, great for dining tables and benchtops.
  • Hardwax oils: A mix of oil and wax, offering both penetration and a protective surface layer.
  • Commercial furniture oils: Easy to apply and widely available, often blended with drying agents to speed up curing.
  • Exterior oils: Specifically designed for outdoor furniture, with added UV and water protection.

Step-by-Step: How to Oil Wooden Furniture

Oiling isn’t complicated, but doing it properly ensures the best results:
  1. Clean the surface – Dust with a soft, dry cloth. For sticky marks, use a damp cloth and let the surface dry completely.
  2. Lightly sand (if needed) – If the wood feels rough, sand lightly with fine-grit paper to open up the grain.
  3. Apply the oil – Use a lint-free cloth or soft brush to spread oil evenly along the grain.
  4. Let it soak – Allow the timber to absorb the oil for a few hours (or as directed on the product).
  5. Wipe off excess – This prevents stickiness and uneven patches.
  6. Let it cure – Give it at least 24 hours before heavy use.

Common Mistakes to Avoid

  • Over-oiling – More oil doesn’t mean better results. Too much will leave a sticky film.
  • Using the wrong oil – Outdoor furniture needs exterior-grade oils; indoor pieces don’t.
  • Ignoring the climate – A routine that works in Perth’s dry heat may not suit tropical Darwin.
  • Skipping preparation – Oiling over dust and grime just locks in the dirt.

Conclusion

So, should you oil wooden furniture? In many cases, yes—especially if it’s solid timber, naturally finished, or exposed to the elements. Regular oiling helps prevent cracks, restores natural beauty, and keeps your furniture ready for everyday use.

Think of it like giving your timber pieces a drink of water. Just a little care, applied at the right time, makes sure they last a lifetime—something every Aussie home deserves.
