Cleaning Bankirai: how to keep your wood in top condition

Many people use household remedies to clean bankirai, but that is not always wise. Read which method really works for a clean and well-maintained patio.

What you need for this tutorial;

Bankirai wood is a strong, durable type of wood widely used for terraces, decking, and garden structures. Thanks to its dense structure and warm color, it has a luxurious appearance. However, without proper maintenance, bankirai can quickly suffer from green deposits, graying, and dirt accumulation. Regular cleaning is therefore essential to extend its lifespan and preserve its natural color.

In this article, you will read exactly how best to clean bankirai, which products to avoid, and how to protect the wood against the elements afterwards.

Cleaning Bankirai: what works and what doesn't?

Many people try to clean bankirai with household remedies such as cleaning vinegar or green soap. These products seem harmless, but over time they can damage the wood or cause uneven discoloration.

It is better not to use these:

  • Green soap: leaves behind a greasy film that attracts dirt.
  • Cleaning vinegar: can leave behind acidic residues that dry out the wood and damage surrounding plants.
  • High-pressure cleaner: damages the wood fibers and makes the surface rough, causing dirt to adhere more quickly.

It is better to use products specifically developed for bankirai hardwood decks:

  • For light soiling or green deposits: Osmo Deck Cleaner
  • For grayed or heavily soiled wood: Osmo Power-Gel Wood Degreaser

Step-by-step plan: cleaning bankirai

1

Choose the right product

Determine whether the wood is only dirty (green deposits, algae) or also greyed. Choose based on this:

  • Osmo Patio Cleaner: for dirt, algae, or moss.
  • Osmo Power-Gel Wood Degreaser: for greying or if the wood has largely lost its color.

  • Distribute the product evenly over the surface.
  • Work in the direction of the wood grain.
  • Allow the product to soak in for ± 20 minutes (for Power-Gel).

Laat goed drogen

Laat het hout volledig drogen voordat je eventueel een beschermlaag aanbrengt. Dit duurt meestal 24 tot 48 uur, afhankelijk van het weer.
