Introduction

The invites are out, the menu is planned, but is the venue ready? Winter leaves a film of green algae, moss, and dirt on decks, patios, and outdoor furniture. Before you host your first summer BBQ, give your outdoor areas a deep clean.

A high-pressure water blaster is the most effective tool for the job—but power must be used with control. Here is how to get the best results without damaging your surfaces.


Choosing the Right Machine

  • Compact (RE 90 - RE 110): Ideal for cars, garden furniture, and small patios. Lightweight and easy to store.
  • Mid-Range (RE 120 - RE 130): heavy-duty cleaning power for larger decks, driveways, and retaining walls.
  • Pro Series: For massive areas or commercial use.

The Secret Weapon: Attachments

Many people make the mistake of using the high-pressure "pencil jet" nozzle on wood. Don't do this! It destroys the wood fibres and leaves permanent etch marks.

Instead, usage a Surface Cleaner (Patio Cleaner) attachment. This looks like a round disc on the end of the lance. It hovers over the ground, using spinning jets to clean evenly without striping the wood or spraying dirty water up your legs.


A clean deck transforms the look of your home. It’s safer (less slippery) and more inviting. Once it's dry, consider applying a fresh coat of oil to lock in the look for the rest of the summer.

  1. Clear the Area: Move all pots and furniture.
  2. Pre-Wash: Wet the surface and apply a specialized deck cleaner (available in-store). Let it sit for 5-10 minutes to break down the grime.
  3. Blast: Use the Surface Cleaner attachment. Work in steady, overlapping passes.
  4. Rinse: Switch to a fan-jet nozzle (set to low pressure) to rinse the dirty foam away.
