- Cleaning solution Water alone is enough to get most exteriors clean if it’s road dust you’re removing. If you have mould or mildew, use a speciality house cleaner designed to kill mould in the pressure washer’s detergent compartment. We used Dulux’s exterior house cleaner and it worked a treat.
- Choose the right nozzle Today it was obvious that this is really important. Your pressure washer will probably have x2 nozzles, one will work in a circular motion and the other will fan based on your requirement. The fan nozzle was the best for the job because you can slow it down to use the cleaning solution and then narrow speed up the jet to remove the mould off spouting and fan it for no damage on the walls.
- Secure windows, doors and pets.We put Frankie inside to stop her drinking the water because of the cleaning solution. Close all the windows and doors before getting started so you don’t overspray inside. Also, put on a pair of safety glasses or sunglasses to protect your eyes from dirt and debris.
- Apply the cleaning solution Our pressure washer has a detergent mixer at the back of the machine. We poured the solution into the container and put the nozzle on slow and coated the house and gutters before we blasted it off.
- Spray at a downward angle. Work with your home’s features and direct your sprayer downward. Never spray into seams or cracks where water can become trapped and damage your house.
- Keep the hose moving. Use a steady side-to-side sweeping motion as you spray your house — lingering too long on one spot can cause damage. If you are using a cleanser, work from the bottom of your house to the top, then rinse from top to bottom.
Once the solution is washed off the house and the house is clean, I would recommend going around with a hose and saturate the plants and grass with water to dilute any harsh side effects. You won’t have to do anything but admire once this is done.
