At Hygienized High Pressure Cleaning, we're passionate about helping you achieve

a sparkling clean for your home exteriors.

Before You Begin:

• Safety First: Wear protective gear like goggles, gloves, and long pants.

• Read Your Machine's Manual: Understand your specific pressure washer's capabilities and safety precautions.

• Test on an inconspicuous area to ensure the pressure and cleaning solution won't damage the surface.

1. Choose the Right Nozzle:

• 0° or Point Nozzle (Use with extreme caution): For tough cleaning stains on hard surfaces or to reach angles pr corners from a distance.

• 15° or "Stripping" Fan Nozzle: A good option for cleaning surfaces with some grime or for more focused cleaning power than a 25° nozzle.

• 25° or Fan Nozzle: A good all-purpose option for most surfaces.

• 40° or Wide Fan Nozzle: Ideal for delicate surfaces like windows or lightly soiled areas or to just simply wash down a surface without the need of a deep clean.

2. Pre-Soak the Surface:

Apply a cleaning solution suitable for the surface you're cleaning. Here's a breakdown of what happens on a molecular level:

• Soaking loosens dirt: The cleaning solution disrupts the bond between dirt particles and the surface.

• Emulsification: Oil-based dirt is broken down into smaller droplets, making it easier to rinse away.

Popular Pre-Soak Solutions:

• Concrete and Driveways: Degreaser for oil stains, mildew remover for mold.

• Siding: Household cleaner diluted with water, specific siding cleaner for stubborn stains.

• Decks and Patios: Wood cleaner specifically formulated for your deck's material.

3. Pressure Cleaning:

• Maintain a distance of 30-45 centimeters (approximately 12-18 inches) from the surface.

• Use a sweeping motion, starting from the bottom and working your way up to avoid streaking.

• Pro Tip: Start with a 40° nozzle for decks, especially if you're unsure about the wood's condition. You can gradually decrease the angle (use a 25° nozzle) for a more aggressive clean if necessary. Always be mindful of not exposing bare wood for extended periods.

Adjust the "Pounds per Square Inch" Pressure based on the surface:

• High pressure ( 2000~4000 PSI): Concrete, stone, brick.

• Medium pressure (1500~2000 PSI): Siding, patios.

• Low pressure (less than 1000~1500 PSI): Decks, windows.

4. Post-Soak with Detergent (Optional):

For heavily soiled surfaces, consider a post-soak with a detergent solution after pressure washing. This can further loosen and remove stubborn dirt.

5. Rinse Thoroughly:

Use clean water to rinse away all cleaning solution and dirt residue.

Safety Tips:

• Always wear protective gear: Goggles, gloves, gumboots and long moisture resistant pants are crucial when pressure washing.

• Maintain a safe distance: Keep the surface cleaner flat on the surface and avoid directing the spray towards yourself or others.

• Be mindful of surroundings: Be aware of nearby plants, pets, or electrical components and take necessary precautions.

Remember:

• For heavily stained or delicate surfaces, consider professional help.

• Start with a low pressure setting and gradually increase as needed.

• Be mindful of nearby plants and cover them if necessary.
