-
Hoses: The arteries of pressure. Invest in durable, high-pressure hoses rated for the PSI output of your pressure washer. Consider the length of hose needed to reach your cleaning targets comfortably.
-
Fittings & Plumbing: The connectors of everything. Ensure all fittings are compatible with your hoses and pressure washer. Use appropriate plumbing for connecting the tank to the pressure washer.
-
Chemical Injector: For targeted cleaning. This allows you to introduce soaps, detergents, and other cleaning agents into the water stream.
-
Nozzles: The instruments of precision. A variety of nozzles will allow you to adjust the spray pattern and intensity for different cleaning tasks.
-
Safety Equipment: Prioritize protection. Include items like safety glasses, gloves, ear protection, and appropriate clothing.
-
Storage Solutions: Order and efficiency. Install shelving, racks, and bins to keep your tools, chemicals, and accessories organized and accessible.
