What is Soft Washing? What is the Difference Between Soft Washing and Pressure Washing

So, what specifically is the difference between soft washing and pressure washing?

Pressure Washing

Pressure washing is the only way to clean tough built-up moulds, mildews, stuck-on dirt or mud, and general grime, on hard surfaces like driveways, cement patios and sidewalks. Special pressure equipment is used to deliver water at high pressure to cut through this build-up, or anything else in the way if the operator is not careful. Handling pressure washing equipment can be pretty tricky and dangerous. Pressurized water can easily injure.

Soft Washing

Soft Washing uses much lower pressure and so, does no damage to more fragile surfaces, like siding or windows. With about 12-volts you can maintain the correct pressure of 60 PSI (Pounds per Square Inch). The detergent does the work of cleaning. Both the detergent and the organic build-up are then rinsed off with clean water at low pressure.

Alblaster uses a cleaning solution that is frequently used today– Sodium Hypochlorite (bleach) with a surfactant (or foaming agent). It is safe for small amounts of this solution to be used with water for cleaning. It is the same solution used for treating drinking water and cleaning swimming pools, although amounts are slightly higher than swimming pool water. With this solution, unsightly and damaging growth is dissolved, and debris is rinsed away with low-pressure water.

Benefits vs Drawbacks of Soft Washing and Power Washing

Washing Treatment TypeBenefitsDrawbacks
Soft WashingGentle cleaning, safe for delicate surfaces – Effective against mold, mildew, algae, and bacteria – Extends lifespan of surfaces – Improves curb appealMay require multiple treatments for stubborn stains – Not ideal for heavily soiled surfaces
Power and Pressure WashingPowerful cleaning for tough dirt, grime, and stains – Removes paint, loose mortar, and graffitiCan damage delicate surfaces if not used properly – Requires more expertise and caution

Know the Difference Between Soft Washing and Pressure Washing

If you do want to keep it all clean and undamaged, the washing process used should be considered carefully. Some parts of your property that have tough, hard surfaces, with a build-up of grime, require pressure washing. Other parts of your property, like shingles (siding), or roofing should be soft washed so as not to damage the surface.

Choosing the Right Washing Method

  • Soft washing is ideal for most exterior surfaces, especially those prone to organic growth like mold, mildew, and algae. It’s a safer option for delicate materials like vinyl siding, wood shingles, and asphalt roofs.
  • Power washing is best suited for tough cleaning jobs on hard surfaces like concrete, brick, and stone. It’s not recommended for delicate surfaces, as the high pressure can cause chipping, cracking, and even structural damage.

Additional Considerations for Power Washing and Soft Washing

  • Always consult a professional: If you’re unsure which method is right for your needs, it’s best to consult a professional cleaning company. They have the expertise and experience to assess your property and recommend the safest and most effective cleaning method.
  • Safety first: Your pressure washing contractor will prioritize safety by wearing proper personal protective equipment (PPE) and following the manufacturer’s instructions carefully.

By understanding the differences between soft washing and power washing, you can make an informed decision about the best approach for your building’s exterior cleaning needs, ensuring that it is sparkling clean.
