How to use
To use the Karcher RM 31 ECO, first determine the appropriate dilution ratio based on the level of soiling and the specific requirements of your pressure washer system. Pour the concentrate into the detergent tank or connect it to the machine's dosing system. Apply the solution to the surface using the low-pressure setting of your pressure washer, allowing it to dwell for a short period to penetrate the dirt. Do not allow the cleaner to dry on the surface. Finally, rinse the area thoroughly with high-pressure water to remove all residues.
What to consider before purchase
Check the material compatibility of the surfaces you intend to clean
Ensure your pressure washer is equipped with a detergent dosing system
Verify local environmental regulations regarding the disposal of cleaning runoff
Calculate the required dilution ratio to estimate total coverage
Usage recommendations
Always wear appropriate personal protective equipment, such as gloves and safety goggles, when handling concentrated cleaning agents. Store the container in a cool, dry place away from direct sunlight and keep it out of reach of children.
