BioMaderas Terrace cleaner for wooden terraces

The terrace cleaner from BioMaderas based on oxalic acid effectively removes dirt, algae, fungi and gray haze from weathered and dirty wooden terraces. Mix, apply, scrub off - done.

Cumaru terrace 90mm, 1 year old, Simon Alber, Stuttgart


✓ Pure oxalic acid without poison
✓ Strong effect on weathered wood
✓ Removes dirt
✓ in combination with BioMaderas Terrace oil brings back the natural color of the wood


The BioMaderas Terrace cleaner is mixed with lukewarm water in a ratio of 1:10 to 1:15, then applied to the swept wooden terrace with a watering can. The floorboards can already be wet for treatment, so that the cleaner acts primarily on the surface and not in the wood. After a 10-minute exposure time, the terrace is scrubbed with a brush. This removes dirt, algae and fungi from the decking. The terrace is then rinsed off with clear water.

  1. Awesome -

    Simply pour the watering can onto the wood, wait a bit, sweep away with a hard broom and keep pouring water over and over again so that all the dirt is washed away. I don't need to say anything about the result, the pictures are clear (I bought too few, hence this transition). Absolute purchase recommendation.

    Ordering was super quick, Mr J's service was top notch. The package came the next day and the day after that the terrace was sparkling clean.

    I used the deck cleaner for the first time on a 2 year old Cumaru wooden deck. The terrace was in the first spring with BioMaderas Terrace oil was treated lightly and looked gray and partly greenish after the winter. I mixed the patio cleaner in a watering can and poured it onto the patio with the spray head. After about 10 minutes I brushed the terrace with an electric scrubber. You can clearly see the result when brushing. The dirt can be removed very easily and what remains is a clean and algae-free surface with the natural wood colour. Then I rinsed the terrace with clear water. Be sure to wear gloves, otherwise your fingers will discolour – how do I know?
    Perfect terrace cleaning without much effort and damage to the wood surface, for example with a high-pressure cleaner. Perfect! Then I have the terrace with me BioMaderas Terrace oil treated light and the terrace looks like new.
