A pressure washer is a simple yet complex device. At first glance, it looks very simple to use. However, when you get into the specifics, you realize how complex it can get. The most complicated thing about a pressure washer is the amount of pressure. The amount of pressure produced by a power washer is usually presented in PSI. This is a unit of measurement for the amount of pressure required for specific cleaning duties. PSI(Pressure per Square Inch ) measures how strong the water jets from a pressure washer are.

The standard PSI range for most power washers is between 1300 to 3000. However, more powerful industrial models have up to 4000 or more PSI. According to experts, the higher the PSI, the more challenges you encounter when washing with a power washer. This post looks at the PSI requirements for cleaning dirt off a sidewalk.

How much PSI do you need to clean dirt off a sidewalk?

Sidewalk cleaning is one of the most common applications of a power washer. The pressure from the machine helps get off stubborn dirt like hardened gum from the surface. When choosing a pressure washer for sidewalk cleaning, the PSI is one of the top factors.

For effective cleaning of your sidewalk, you need a good amount of pressure. Additionally, you would also benefit from a decent water flow rate. Expert pressure washers recommend around 3000 PSI. This is enough pressure to handle the toughest dirt on your sidewalk. For instance, water flowing at 3000 PSI can easily break down hardened dirt, gum and remove old grease and paint stains from your sidewalk.

Heavy-duty pressure washers can achieve 3000 PSI. Other than effective cleaning, another benefit of using a 3000 PSI pressure washer for sidewalk cleaning is that it takes a shorter time. A heavy-duty machine with this PSI range can quickly clean large areas without too much energy.

Tips for effectively pressure washing your sidewalk

With a 3000 PSI pressure washer, you need the right handling tips to prevent injuries and accidents. This amount of pressure can cause significant damage when it is directed towards the wrong object. For instance, directing the water at a person could cause severe injuries. The following tips should come in handy when pressure washing your sidewalk;

  • Ensure to wear protective gear and clothing
  • Use hot water to remove stubborn dirt like hardened soil and gum
  • Maintain a safe distance and ensure the area is clean before powering the machine
  • Use the right detergent to speed up the power washing process

Final Word

Besides the PSI, when choosing the right power washer for getting dirt off your sidewalk, you also have to consider the GMP. This is an abbreviation for Gallon Per Minute. It refers to the measure of the amount of water the machine uses. The lower the GMP value, the more water efficiency, and vice versa. The GMP is more often than not directly related to the PSI. For instance, the higher the PSI, the higher the GMP.
