The difference seems obvious enough: a soft wash releases a softer amount of pressure & hard pressure wash requires much more force.
However, there’s a little bit more to understanding the difference in a soft and hard pressure wash when it comes to choosing which service will benefit you best. It’s common for people to think that the more pressure applied to a surface, the faster the results.
However, this is not always the case. In fact, if a pressure washer isn’t being used properly, there can be more damage to your facility. This is why it’s important to understand when a soft wash will be more beneficial depending on the service you require.
So, we’re going to highlight the main differences and which situations are best for each service!
Hard Pressure Washing basics:
A standard pressure wash releases an amount of pressure in a PSI unit (pounds per square inch) of at least 2500. It is the kinetic energy force from a pressure wash that is doing the actual cleaning. Pressure washers are awesome, but they also can cause damage to your building if too much pressure is applied to the surface.
A PSI of 2500 means that it is highly powerful and must be handled by someone who has experience or after you have carefully read all the directions. It is extremely important that someone who is using a pressure washer is properly dressed and careful with their surroundings–especially other people and animals.
Soft Pressure Washing Basics:
A soft pressure wash is usually opted for more often because of its ability to get off algae. The PSI is usually set less than 1000 PSI. However, just because it is a substantially less amount of pressure does not mean that it cannot cause any harm to humans or animals. It is really important that you are aware of the chemicals that soft washes use to get clean surfaces. This is how a soft wash gets the job done–by using cleaning solutions that soak into the surface and then gets rinsed off.
So, which one do you need?
Opt for a soft wash if you’re trying to clean off a more fragile surface or:
- window screen
- plant life (such as algae) because the low pressure and the right chemicals get rid of the spores (if you have mold, you may need to consult a mold specialist)
Opt for a hard pressure washing if you’re trying to clean off dirt, grease, grime, gum, and/or graffiti on a less fragile surface:
