Before you begin, be sure to wear protective clothing and goggles to shield yourself from water spray and debris. Ensure your ARXP pressure washer is properly connected to electrical and water supplies.

Start by pre-washing the wall with your pressure washer to loosen and soften any built-up grime. Use the adjustable jet nozzle set to the fan spray setting to evenly wet the entire surface.

Included Accessory: Adjustable jet nozzle

Insert the Walls & Stones detergent into the high-pressure foam lance included with your pressure washer. Apply the detergent solution evenly across the wall surface, ensuring full coverage over all areas to be cleaned. 

If you don’t have a dedicated pressure washer detergent, you can skip this step.

Optional Accessory: WALLS & STONE Detergent

Once the detergent application time has elapsed, proceed with deep cleaning to remove ground-in dirt and grime. For this step, use the adjustable jet nozzle set to a tight, concentrated stream or the rotary jet nozzle for extra cleaning power on stubborn dirt.

If the wall has a more delicate surface (e.g. painted wall, brick, thermal coat) use the adjustable jet nozzle with fan opening, without getting too close. 

If using a BOX5 DTS or BOX4 DSS, we recommend the FAST MODE setting for non-delicate surfaces (like unpainted metal). Otherwise, use ECO MODE.

Included Accessories: Adjustable jet nozzle / Rotary jet nozzle

Thoroughly rinse the wall using the adjustable jet nozzle with fan opening to completely flush away any remaining detergent and dirt. Be sure to pass the water jet across the entire surface for full coverage.
