Do Karcher Detergents Improve Results?
Yes. Karcher detergents reduce cleaning time, break down stubborn dirt faster and protect certain surfaces. Using the correct formula prevents damage caused by using overly strong or incorrect chemicals.
Tip: Always check that the detergent is compatible with your pressure washer model.
How To Apply Karcher Detergent
- Fill the detergent tank or attach a detergent bottle (depending on model)
- Apply at low pressure using a wide-angle spray
- Allow 2–5 minutes dwell time
- Rinse at medium pressure
