How it works

A surface-led cleaning process

The correct method depends on the material, its condition, and the growth present. Assessment comes before pressure, solution, or equipment choice.


Softwashing

Treat growth at the source

Softwashing uses low pressure and a controlled cleaning solution so organic growth can be treated thoroughly—often reducing the need for aggressive pressure on suitable surfaces. We prepare with plant-aware rinsing in mind; no clean is zero-risk, and not every surface suits every method.


  1. Low pressure

    Cleaning solution is applied gently—so surfaces are treated, not blasted.

  2. Controlled solution

    A measured mix targets mould, algae, moss, lichen, and organic growth.

  3. Dwell time

    The treatment works at the source while we watch over plants and surrounds.

  4. Thorough rinse

    Residue is rinsed away, leaving a cleaner surface ready to stay that way longer.

Method choice

Softwash versus pressure washing

The correct method depends on the material and condition. Pressure washing is not universally wrong—it is simply the wrong tool for some surfaces.


Soft washing

  • Low-pressure application
  • Controlled cleaning solution
  • Organic growth on suitable exterior surfaces
  • Treats growth at the source rather than blasting it off

Pressure washing

  • Higher-pressure water where the surface can take it
  • Suited to durable hard surfaces
  • Concrete, paths, patios, pavers, some retaining walls
  • Used when pressure is the right tool—not by default

How it works

Four careful steps

From first look to final rinse, the Cleanline approach keeps the process clear and surface-led.


  1. 1 Assess

    We identify the surface, contamination, and the method that fits.

  2. 2 Protect

    Plant-aware preparation and careful setup around sensitive areas.

  3. 3 Treat

    Soft wash, pressure wash, or pure-water windows—chosen for the material.

  4. 4 Rinse and report

    A thorough finish, then a clear summary of what was done.

Clean the growth. Keep the surface.
