Most people reach for oil when it’s time to care for their wooden terrace. But in the Nordic tradition, there’s another way - one that keeps the wood beautiful, soft, and naturally weather-resistant without sealing it under a sticky layer. It’s called såpskurning, or soap cleaning.

When you clean your terrace (or any wooden surface outside, like our jetty here in the picture) with linseed oil soap, the natural fatty acids in the soap penetrate the wood fibers, gently nourishing and protecting them from within. Over time, this builds up a subtle, breathable surface that repels dirt and moisture - while allowing the wood to age gracefully and evenly in the open air.

Unlike oil, which can darken wood, attract dirt, and eventually flake or become patchy, soap cleaning preserves the natural tone and texture of the wood. The surface stays light, matte, and easy to maintain - no sanding, stripping, or re-oiling needed.

Soap cleaning is also kinder to nature: no solvents, no harsh chemicals - just pure, linseed soap made from biodegradable linseed oil, and water.

A beautiful, low-maintenance way to let your terrace stay exactly as it should be: alive, natural, and weathered with dignity.

1. Prepare the surface
   
   Brush off loose dirt. Sweep and lightly rinse the terrace.
   
2. Mix the solution
   
   Add 1–2 tablespoons of linseed oil soap per liter of warm water.
   
   For dry or weathered wood, use a slightly stronger mix. Let it sit for a few minutes to soften the surface.
   
3. Scrub along the grain
   
   Dip a brush into the solution and scrub thoroughly, following the direction of the wood grain. A light lather will form — this is expected.
   
4. Remove dirty water
   
   Rinse or brush away the dirty soap solution.
   
5. Final treatment (do not rinse)
   
   There are different ways to do this and Swedish families all have their preferred technic.
   One way is to prepare a fresh solution from the rest of the såpa (ca 3-4 dl/ 25m2). Here you want the såpa solution to be more concentrated. Apply it evenly and leave it on the surface. Scrub it in lightly and let it dry.
   
   Another way to do this step is to spray the solution on the terrace.
   Another third way is to simply roll on concentrated såpa on the WET terrace. It is very important that the terrace is wet - never put såpa on dry wood!
   Do not rinse. Let it dry naturally.
   

The remaining soap helps maintain the wood and contributes to a more even, protected surface over time.

1. Repeat regularly
   
   With repeated use, a subtle protective layer builds up. The wood becomes smoother, less prone to drying, and easier to maintain.

My friend Linda and I did a little test on her terrasse in Stockholm. The wood had not been treated or cared for in years and was really dry.
All we did was a quick scrub on three planks to to check the difference.

We used the unscented Såpa from Pataholm. You can find it here in 500ml bottles. We also have the same product in a 2,5L. That one can be found here.
