How Long Does It Take to Pressure Wash a Semi Truck?

Owning a semi-truck can be an expensive affair. It is essential to properly maintain the vehicle in order to ensure that it runs smoothly and efficiently.

Pressure washing is one of the most effective ways to keep your semi-truck clean and well maintained. But, it is important to understand how long does it take to pressure wash a semi-truck before you begin the task.

The time taken to pressure wash a semi-truck depends on several factors such as the size of the truck, how much dirt and grime are present, and the type of cleaning solution used. On average, it can take anywhere from two to five hours to fully clean a semi-truck with a pressure washer.

The process of pressure washing begins with prepping the truck for cleaning. This includes removing any loose debris or dirt from the body of the truck, as well as any other parts that will be exposed during cleaning. Once this is done, you should rinse down the entire truck with a garden hose or sprayer in order to loosen up any dirt or debris that may have been missed during prepping.

Once everything has been prepped, you can then start pressure washing your semi-truck using a high powered pressure washer. Start at one end of the truck and move slowly along its length until you reach the other end. Make sure that you use an appropriate detergent or cleaning solution that is designed for use on vehicles in order to get optimal results.

When pressure washing your semi-truck, be sure to keep an eye out for any areas that may require extra attention such as rust spots or any areas where mud might have accumulated. You should also pay close attention to areas around windows and mirrors where dirt tends to accumulate more easily.

Once all areas have been washed thoroughly, rinse down your entire truck again with water before allowing it to air dry completely. This will help ensure that no residual soap or cleaning solution remains on your vehicle’s surface.


Pressure washing a semi-truck can take anywhere from two to five hours depending on its size and condition as well as what type of detergent or cleaning solution used for optimum results. It is important to properly prepare your vehicle before starting the task and pay close attention when rinsing off any stubborn dirt and grime from its surface.
