Cleaning WPC decking boards with high pressure
Our WPC decking is now in its 3rd year and still looks great – and there are no haptic defects either. The floorboards are still splinter-free and undamaged. Only the green algae coating on the shady parts of the terrace was a nuisance during my tour in spring.
Last spring, I had already sprayed the WPC decking with my Kärcher high-pressure cleaner and removed the dirt and algae deposits. It worked, but it left these ugly streaks on the wood.
Kärcher power scrubber for decking boards?
To avoid streaking in my yard this year, I researched various forums and came across the Kärcher power scrubber.
This scrubbing brush, which is much more than an ordinary broom, can be easily connected to an existing high-pressure cleaning device.
The three nozzles on its underside powerfully spray the dirt away, while the hard nylon bristles effectively remove the dirt with every sweeping movement.
I found the rubber lip on the back of the scrubber particularly practical, which makes it easy to remove water from smooth surfaces.
Encouraged by numerous positive reviews, I decided to order the scrubber.
As soon as I received it, I used it for the first time yesterday and was impressed by the performance and efficiency with which it cleaned the yard.

Installing decking brooms
The Kärcher broom reached me in three individual parts by post. Assembly was quick and uncomplicated, without any tools.
The connection with the handle gun of my Kärcher high-pressure cleaner took some getting used to at first. I had to snap the bar into place, similar to other accessories, and then tighten a stabilizer towards the handle.
However, this step was neither difficult nor complicated.
Once I had supplied the Kärcher high-pressure cleaner with water and electricity, I was able to start the cleaning work.
I was thrilled from the very first moments. The combination of the bristles and the three water jets cleaned my WPC decking boards extremely effectively without leaving streaks, shadows or spray marks.
To my surprise, the floorboards were much dirtier than I had expected.
I took some photos after cleaning to document the impressive difference. The change was particularly noticeable at the edge of the terrace.

Cleaning decking boards with the Kärcher – disadvantages
The cleaning result of the Kärcher power scrubber convinced me at first glance, but I did notice some disadvantages.
The scrubber could not clean right up to the wall, but left a gap of about 5-10 cm. This forced me to change the direction of the sweeping movement more often or to clean the affected areas, such as the small wall, in other ways, which proved to be difficult.
I also realized that the scrubber was too small for my height of 185 cm, which led to a stooped and after a while uncomfortable posture. I would have liked Kärcher to have produced a version that was about 20 cm longer.
Another disadvantage was that my shoes (and socks) got wet, although there was hardly any splashing water as the water jet starts inside the bristles. Nevertheless, my feet were exposed to the water during the typical sweeping movements.
As a solution, I recommend choosing appropriate footwear such as rubber boots or the option of going barefoot.
Overall, I give the appliance 4 out of 5 points.
It is interesting to note that I did not use any chemicals at all. Although the Kärcher allows cleaning agents to be added to the water, I stuck to my decision to clean the WPC decking boards without chemical cleaning agents.
However, if I decide to use cleaning products in the future, I will share my experiences with them.

Risks associated with high-pressure cleaning of WPC decking boards
Using the pressure washer enabled me to remove dirt and algae quickly without having to put in a lot of physical effort.
However, during my research I quickly discovered that using a high-pressure cleaner on WPC materials also carries risks.
The strong force of the water jet can roughen the surface of the planks and impair their aesthetics. This not only leads to an unsightly appearance, but can also encourage dirt to adhere.
There is also a risk of water penetrating the material joints and damaging the floorboards from the inside, which can significantly affect their longevity.
To minimize these risks, I adapted the cleaning method accordingly. I took care to reduce the water pressure to a level suitable for WPC boards and to keep the jet at a safe distance so as not to damage the surface.
Cleaning WPC decking boards with the T-Racer
In view of the disadvantages, especially the unhealthy posture, that I experienced when cleaning my WPC decking with the power scrubber, I set out to find a better solution to my problem.
After some time, I came across the T-Racer from Kärcher, a device that is also connected to a high-pressure cleaner to remove dirt from decking boards.
In my experience, the T-Racer delivered a better cleaning result than the power scrubber.
Handling proved to be easier and more comfortable, even for a tall person like me.
I have recorded my detailed assessment and my conclusion on patio cleaning with the T-Racer in spring 2015 in an article that you are welcome to read.

Video – Comparison of tiller vs. scrubber vs. T-Racer
I have cleaned my WPC decking and also my BPC decking with a high-pressure cleaner in the past. In addition to the power scrubber and the T-Racer, I also tried out the normal dirt blower.
In my comparison of the three systems, the T-Racer convinced me the most. You can also find my video WPC patio cleaning – comparison of Kärcher tiller vs. scrubber vs. T-Racer in my playlist Test | Experience | Conclusion.
