The Science of Pressure Washing

Why Professional Pressure Washing Matters

Pressure washing, also known as jet washing or power washing, is an effective way to clean driveways, patios and building exteriors. However, achieving the best results requires more than just high-pressure water.

At Ex Clean, we understand the science behind cleaning methods, ensuring safety and efficiency.

Pressure vs Flow Rate: The Key to Effective Cleaning

Many people believe that higher pressure alone guarantees better results but this isn’t always the case. Professional pressure washing services like Ex Clean use the right balance of pressure (measured in bar or PSI) and flow rate (litres per minute) to achieve superior results while protecting surfaces.

Water Pressure (PSI/Bar) – The Power Behind Cleaning

High pressure is useful for removing stubborn dirt and grime but excessive force can damage delicate surfaces like wood or brick mortar. Ex Clean assesses each surface before adjusting the pressure accordingly. Not all surfaces need high pressure!

Flow Rate (Litres per Minute – LPM) – The Efficiency Factor

Flow rate determines how much water is delivered per minute. A high flow rate rinses away loosened dirt more effectively making it a crucial factor in professional cleaning.

Why DIY Pressure Washing Poses Risks

Attempting to pressure wash surfaces without proper knowledge can lead to costly damage. Incorrect pressure settings can damage materials, strip paint, erode mortar or even cause injury. We use commercial grade equipment and trained operators to ensure safety and quality results.

The Right Pressure and Flow Rate for Different Surfaces

Professional externasl cleaners tailor their approach based on the surface they’re cleaning. Wood needs treating differently to concrete, likewise, concrete is tret different to tarmac! We know our surfaces and know how to clean, restore and protect them!

Why Professionals Use Hot Water or Steam Cleaning

While cold water pressure washers are great general cleaning, hot water pressure washers are superior for removing grease, oil, and industrial grime. Ex Clean has access to these advanced machines, ensuring deeper and more effective cleaning.

Using the Right Nozzle for Maximum Efficiency

Pressure washer nozzles are a subject of tyheir own! There are so many to choose from that this can become confusing to the untrained! We always assess anmd select the appropriate nozzle for each job to avoid unnecessary damage.

The Role of Cleaning Detergents

For tough stains, we use specialised detergents alongside soft washing techniques. This approach enhances cleaning results while minimising surface damage. Eco-friendly chemicals are always used when possible and up,ost care is taken to protect your property and the surrounding environment.
