Frequently Asked Questions

Gas pressure washers are ideal for cleaning larger areas, as well as areas that are not sensitive. Some common items cleaned with gas powered pressure washers include:

  • Driveways
  • Sidewalks
  • Wood decks (when combined with a surface cleaner)
  • Pool areas
  • Hard home siding (e.g., brick or cement)
  • Paint and deep stain removal from cement and other hard surfaces

In general we prefer electric pressure washers for vehicle cleaning (autos, trucks, SUV's, etc), because they shut off when not in use and produce less pressure overall – but vehicles can be cleaned with gas pressure washers if you pay proper attention to nozzle selection and do not allow the pressure washer to idle for more than a couple minutes between spraying.

Some pros typical of gas powered pressure washers (compared to electric powered):

  1. Higher pressure output (PSI)
  2. Can be operated without an electrical source
  3. Durable metal frames and components
  4. Pro-level options like triplex pumps
  5. More service options for extended life

Some potential tradeoffs of gas powered pressure washers (compared to electric powered) include:

  1. More expensive / higher initial investment
  2. Generates fumes and significantly more noise
  3. Requires gas on hand to operate
  4. Requires more effort to start and maintain
  5. Heavier and takes up more storage space

These pros and cons make general assumtions, each model will have its unique advantages and features. Both gas and electric pressure washers are capable of most home cleaning tasks, but where appropriate a gas pressure washer may reduce your cleaning time and clean more thoroughly. The decision of which type of pressure washer to use is an individual one – some people choose to use both types.  :) 

There are many brands and formulas available – just be sure to only use detergents that are specifically formulated to work with pressure washers. We make two formulas that are thoroughly tested to work with our gas and electric pressure washers: a Multipurpose Detergent and a Vehicle Wash & Wax. These formulas make up to 20 gallons of ready-to-use detergent from one gallon of concentrate and are Made in the USA.

Our gas pressure washers are equipped with either a detergent tank or siphon hose, to make working with detergents easy and convenient. 

Tip: NEVER run bleach through the detergent tank or siphon nozzle. It can damage the pump and will void your warranty.
