Its concentrated formula makes up to 40 gallons of cleaning solution, making tough cleaning jobs easier. Fast-acting and built for tough pressure wash jobs, it cleans and rinses without leaving any residue. This phosphate-free and powerful cleaning formula is designed to deliver exceptional results. Directions: Pour it into your pressure washer's onboard detergent tank or connect the siphon tube to the product container. Refer to your pressure washer owner's manual for specific instructions. Adjust the metering valve if available to achieve the desired strength. For optimal results, start spraying from the bottom up, allowing the detergent to penetrate surface dirt for 1-5 minutes. Avoid letting it dry. Rinse the surface at high pressure with clean water. For stubborn dirt, a soft bristle brush can be used. Remember to wash from the bottom up and rinse from the top down for the best outcome. If you prefer using a foam cannon, the Karcher Concrete & Driveway cleaner can be easily applied by placing it in the foam cannon bottle. Adjust the foam cannon metering valve to your desired strength and follow a similar washing process as described above. For manual application, dilute the detergent by mixing 1 part with 39 parts water. Adjust the strength according to your needs. Apply the solution to the surface for 1-5 minutes, ensuring it doesn't dry. Rinse with high pressure from the top down. Note: Always test on an inconspicuous area first.
