Pressure Washing Vs Soft Washing - Which One is For You

Pressure cleaning using commercial equipment
Heavy duty pressure cleaning

Certainly! Both pressure cleaning and soft washing are popular methods used to clean various surfaces, especially the exterior parts of homes and buildings and concrete. Each has its advantages and appropriate applications. Let's break down the differences and best use cases for each method:

Pressure Cleaning:

  1. Definition: Pressure cleaning uses high-pressure water spray to remove dirt, mould, grime, dust, mud, and other contaminants from surfaces and objects.
  2. Equipment: Typically involves a pressure cleaning machine that can release water at high pressures. The pressure can be adjusted depending on the job requirement.
  3. Uses: Ideal for cleaning hard surfaces like driveways, footpaths, brick walls, patios, and concrete surfaces. It's also used for surfaces that have heavy-duty grime or stains.
  4. Advantages:
    • Rapid and effective for tough dirt.
    • Suitable for surfaces that can handle strong water pressure.
    • No chemicals needed (though sometimes detergents might be added for tougher stains).
  1. Disadvantages:
    • Can damage softer surfaces or surfaces with existing damage.
    • Will not be as effective for killing mould or mildew as the spores won’t be completely removed.

Soft Cleaning:

  1. Definition: Soft washing uses low-pressure water, combined with specialised cleaning solutions, to gently cleanse surfaces without the potential damage that might come from high pressure.
  2. Equipment: Soft wash systems are typically equipped with a low-pressure pump, water tank, and a blend of biodegradable chemicals.
  3. Uses: Perfect for more delicate surfaces like vinyl siding, wood panelling and painted wood, It’s particularly effective for areas with mould, mildew, algae, or other biological contaminants.
  4. Advantages:
    • Safer for delicate surfaces.
    • Chemical solutions effectively kill and prevent mould, mildew, and algae.
    • Consumes less water than pressure cleaning.
  1. Disadvantages:
    • Chemicals must be chosen carefully to ensure they don't harm plants or pets.
    • Not as effective for very tough, non-biological stains.
    • Some people might have environmental concerns regarding the cleaning solutions.
    • Good operators use bio friendly chemicals, mainly chlorine which break down easily so as not to harm surfaces.

Which One is For You?

  • Determine the Surface: If you're dealing with a hard, sturdy surface with tough grime, pressure cleaning is your go-to. If you're trying to clean a delicate surface or tackle biological growths, soft washing is a better choice.
  • Environmental Concerns: Soft washing requires chemicals, usually biodegradable. If you're particularly eco-conscious, you might opt for pressure cleaning with just water or environmentally friendly detergents.
  • Frequency of Cleaning: If you're looking for a method that provides a longer-lasting clean by tackling the root of the problem (like mould and mildew), softwashing might be a better long-term choice.
  • Cost & Equipment: Pressure cleaners are more common and might be cheaper to rent if you're doing a DIY job. Soft washing might require professional help due to the chemicals and equipment involved.

In conclusion, the choice between pressure cleaning and soft washing depends on the specific needs of your cleaning project. It's always a good idea to consult with professionals or do thorough research before deciding on a method.
