The Kobalt KPW-1700 is equipped with a detergent tank for applying cleaning solutions. Only use detergents specifically designed for pressure washers to avoid damage to the unit or the surfaces being cleaned. Pour the detergent into the tank, ensuring it doesn’t exceed the maximum fill line.
To activate detergent flow, typically you’ll need to attach the soap nozzle (often white in color) and adjust the detergent selector dial to the “detergent” or “soap” setting. The washer will then draw detergent from the tank and mix it with the water stream.
Apply the detergent solution evenly to the surface, allowing it to dwell for a few minutes before rinsing. Avoid letting the detergent dry on the surface. After applying detergent, switch back to a cleaning nozzle and rinse thoroughly with clean water. Always follow the detergent manufacturer’s instructions.
Proper Spraying Techniques
Effective cleaning with the Kobalt KPW-1700 relies on proper spraying techniques. Maintain a consistent distance from the surface – generally, 8-12 inches is a good starting point. Begin with a wider nozzle (like the 25-degree or 40-degree) and test on an inconspicuous area to assess the pressure and avoid damage.
Use sweeping motions, overlapping each pass slightly, to ensure even cleaning. Avoid holding the nozzle too close, as this can etch or damage the surface. For stubborn stains, you may need to reduce the distance or switch to a narrower nozzle (like the 0-degree), but exercise extreme caution.
Always spray in a downward motion to prevent water from being forced under siding or into electrical outlets. Work from top to bottom, allowing gravity to assist with rinsing. Rinse thoroughly after cleaning to remove all traces of detergent and loosened dirt.
