The Karcher RM 110 Water Softener and Limescale Inhibitor is a liquid made for HDS pressure washers. Those are the hot water machines. Hard water leaves limescale inside the heater coil. This 1 litre bottle is how you fight that.
It stops limescale building up in the heater coils. That protects the part of the machine that matters most. It also helps cut the risk of repairs and downtime. Karcher says it suits all HDS pressure washer ranges.
Check your model before you skip it. On the HDS7/10-4M, HDS7/10-4MX and HDS7/9-4M, regular use is mandatory. Without it the warranty on those machines becomes invalid. The 1 litre bottle is easy to store and handle. A 5 litre size is also listed.
Who is it for? Anyone running an HDS machine who wants it to last. The compact bottle suits single operators and small fleets. It is a simple routine job that protects a costly machine.
