Same summary

The Karcher wood cleaner RM612 1L, 6.295-757.0, is suitable for users who want to gently but effectively clean wooden terraces, fences or other outdoor wooden elements. Thanks to its proven compatibility with Kärcher K2–K7 high-pressure cleaners, it is easy to use and adapted to these models, thereby reducing the risk of surface damage. The special feature of this cleaner is its dedicated wood formulation, which makes it less suitable for harder or heavily soiled surfaces that would require more aggressive agents or attachments. Users looking for a compromise between wood protection and efficiency will appreciate the balance of gentleness and cleaning power.

Answers to frequently asked questions

Is the cleaner also suitable for varnished or oiled wooden surfaces?

The cleaner is intended for natural and protected wooden surfaces, but we recommend testing on a less visible area, as different coatings may react differently. If you have an exterior wooden surface with a sensitive coating, use the cleaner in a lower concentration and a softer jet setting.

Which Kärcher pressure washer models does the cleaner support?

The cleaner is compatible with all Kärcher cleaners from the K2 to K7 series; use with other brands has not been tested.

Does the cleaner also remove stubborn green or black discoloration of wood (e.g. moss, algae)?

With regular use, it can effectively help remove surface green-gray discoloration (moss, algae), but for heavily ingrained stains, we recommend additional mechanical assistance with a gentle brush.

How do I properly dose the cleaner into a high-pressure cleaner?

Dosage depends on the cleaner model; usually the cleaner is poured into a dedicated tank or the “Plug'n'Clean” system is used. We recommend following the instructions for your Kärcher cleaner for the optimal water to detergent ratio.

What to do if stains or whitish spots remain on the wood after cleaning?

If whitish stains appear, rinse the surface with a large amount of clean water and check the amount of detergent used. Excessive amounts may leave traces, so reduce the dosage or use a gentler jet setting the next time you use it.
