Kärcher Karcher Foam Blocker RM 761 2.5l 6.291-389.0

Highly effective Foam Inhibitor RM 761, 2.5 L from Kärcher, specially developed for use in the wastewater tank or defoamer tank of carpet cleaners, scrubber dryers, and wet vacuum cleaners. The cleaning agent is added directly to the wastewater tank and effectively prevents excessive foam build-up—ideal for professionals in the building cleaning sector, as it avoids interruptions during cleaning. This allows the wastewater tank to be filled completely without the float being triggered too early and without damaging the suction turbine.
