Question about Kärcher Universal cleaner RM 626

WPC decking is often sensitive to aggressive cleaning agents, so you should make sure that the product is not too aggressive. The RM 626 is pH-neutral and biodegradable, which makes it suitable for many applications. Nevertheless, it is advisable to test on a small, inconspicuous area before use to ensure that no damage occurs.
