Things You'll Need
Honda powered pressure washer
Downstream injector system with soap tube
Pressure washer detergent
Allow the detergent or chemical to do its job by letting it sit for the recommended time to save time and effort when rinsing.
Take the time to properly compute your chemical dilution ratios when mixing the solution. If your machine has an adjustable rate injector, check the setting often, as engine vibration can cause it to change.
Cover any electrical outlets and avoid electrical wires and light fixtures.
Wear eye protection and gloves to protect from soap spray and loose dirt.
Honda-powered pressure washers are a popular tool for cleaning with both the home owner and contractor. Using the downstream soap injector to apply the right cleaning solution for the job saves time and labor. The soap tube system is used to deliver the detergent solution directly to the surface to be cleaned, eliminating extra steps and equipment.
Mix the soap or detergent solution in the bucket using the manufacturer's directions, taking into consideration the water-to-chemical dilution ratio of your downstream injector. This ratio is found in your pressure washer's manual. These are usually fixed at approximately a 10-1 dilution rate. If the suggested dilution is 10-1, you can use the product as is. If a 20-1 ratio is recommended for application, you will need to mix half soap and half water.
Attach the black low-pressure soap tip to the wand, and connect the pressure washer to your water source. The gallons per minute, or GPM, flow rate of the source should be at least as high as your machine's rating. Run water through the system for a couple of minutes by releasing the trigger gun.
Place the filter end of the soap tube into the bucket of soap solution, making sure the filter is all the way to the bottom of the bucket.
Attach the other end of the soap tube firmly to the injector nozzle on your pressure washer's pump. The location of this can be found by checking your manual.
Start the pressure washer and set your water pressure and engine speed according to the manual's instructions.
Apply the soap solution to the surface to be cleaned with even side to side passes, starting at the bottom and working to the top on vertical surfaces to avoid streaking. On horizontal surfaces, work according to the water's drainage pattern. Allow the soap to dwell on the surface for a few minutes to do its job, but do not allow the surface to dry.
Remove the black soap tip, and replace it with the appropriate tip for rinsing. Refer to your manual for tip sizes and uses. Rinse the surface clean of any soap, starting at the top and working down. Reapply soap to problem spots as needed, allow to sit, and rinse again. Rinse any soap from the area and from any plants or objects nearby.
