9 Pressure Washing Tips For Fleet Cleaning

For commercial cleaning contractors there are plenty of fleet washing jobs to take on. Start the job with the best pressure washer because, for every truck that needs cleaning, the application will be different. Here are our top pressure washing tips for fleet and truck cleaning and a few additional insights to help you grow your commercial cleaning business.

Power Wash Tip # 1: Temperature

The warmer the climate, the easier it will be to power clean the trucks. During those cooler and cloudier days, you may find yourself needing to power wash a second time because the soap did not penetrate as quickly as expected.

Power Wash Tip #2: Prep for Power Washing

To ensure an efficient cleaning job, create a preparation list, which includes detailing the following information:

  • Type and quantity of fleet
  • Frequency of cleaning
  • Availability of water
  • Wash water recovery system
  • Degree of cleaning required, which will influence the type of power washer you’ll need
  • Inspection of the fleet for open windows, oil leaks and other pre-existing damage to the equipment
  • Follow manufacturer’s instructions for any chemical use or restrictions on the trucks, including strict adherence to specified dwell time.

Power Wash Tip #3: Environmental Regulations

Always comply with environmental regulations. Be sure to create a space where wastewater is collected and prevented from going into a storm drain.

Power Wash Tip #4: Equipment and Supplies

Basic Pressure Washer Requirements:

  • Hot water pressure washer, 60°C minimum with the capability of four to six GPM at 2000 to 3000 PSI, or
  • Standard System design provides five GPM at 2500 to 3000 PSI that heats water to 93°C

From experience, the people at Unimanix usually custom designs and builds the washing equipment and systems for fleets and trucks. Please contact your local Unimanix representative for more information.

Industrial Pressure Washer Accessories & Supplies:

The following is usually required:

  • Six foot or longer wand with a ball valve shutoff
  • Shorter wands for difficult-to-reach areas
  • 40-degree nozzle
  • 25-degree nozzle
  • Downstream injection system for soap and brightener
  • Flow control
  • Low-pressure sprayer

Power Wash Tip # 5: Wash Site Selection

As a commercial cleaner, you will need to stay up-to-date and understand local environmental regulations as well as use the right chemicals and select the proper site for washing. Make sure you follow governing laws for disposal via sewers or establish a system to collect wastewater and dispose of it according to local rules.

Fleet washing does require an investment in a facility with wash bays and direct connections to sanitary sewers. At Unimanix, we’ve worked with power washing contractors to find the best wastewater solution for their growing business. Contact us for more information.

Power Wash Tip #6: Fleet / Truck Washing Techniques - Single Step Fleet Washing Method

A popular washing technique is the single step method, where soap is applied under high pressure with heat, followed by a rinse.

Power Wash Tip #7: Two Step Power Wash Method For Fleet / Truck Cleaning

A fleet with an excessive amount of grime, grunge and faded aluminium will need additional cleaning. For aluminium brightening, start with an acid or aluminium brightener, followed by soap and then rinse.  

If you are using soap that doesn’t remove road film, you may find yourself needing to hand brush with the soap, followed by a rinse.

Power Wash Tip #8: Cleaning Interior of Enclosed Trailers

Enclosed trailers are more aligned with tank cleaning and should follow regulatory requirements for safety and cleaning. Also, please note that if trailer trucks are used to move fresh food or anything perishable, regulations for this type of cleaning can be subject to recordkeeping that includes cleaning, sanitising, and inspecting transportation equipment.

Power Wash Tip #9: Billing

When bidding on fleet washing jobs, remember to include the cost of detergent. The quality of the soap used should also be factored into the price as it will have a direct result on labour costs. A superior soap will produce better cleaning results and may also help to speed up the job.

Finally, trucks and other vehicles that are frequently washed are easier to clean. Price accordingly to the time and frequency required to pressure wash the vehicles properly.
