Purchase Only What You Require: Factors to Consider

All the numbers in the specs can be confusing for some of us. When looking at the specifications of gas-powered pressure cleaners, keep these in mind:

• PSI – pounds of force per square inch – shows how strong a sprayer is
• GPM – Gallons per minute – refers to the rate of water flow, hence how much of it is used

Be on the lookout for a cleanser that gets the job done most effectively, irrespective of the surface you will be cleaning. All these machines have different features that are helpful in multiple ways. For example:

• Tall users – should look for sprayers carrying fold-down handles with adequate extension to prevent constantly bending to move the machine.
• Users with back complications – should locate a lightweight washer. Keep in mind that adding oil, gas, and water will raise the listed weight.
• Users with multiple surfaces to clean – should get a machine with various nozzle tips, variable pressure, as well as other attachments.

Remember To Winterize Your Washer

For users who experience cold winters, be sure to winterize the gasoline cleaner before you can store them. This ensures you start it without issues come spring. You can check for winterizing instructions user manual that came with your product. Essentially, the process involves filing an internal tubing system and pump with an RV-class antifreeze. If your machine will be in storage for over a month, the rule of thumb is to drain all the gas from the fuel tank.

If you still need help, this video will demonstrate winterizing a pressure cleaner.
