How do I clean/replace the spray tips on my surface cleaner?

Here's what you can do:

1. Turn off the pressure washer and turn off the water supply. Release the residual pressure by squeezing the gun's trigger.
2. Disconnect the pressure washer wand from the surface cleaner.
3. If you have the 14.5" Stainless Steel Surface Cleaner or the 20" Surface Cleaner use a 14Mm 6-point wrench or a 9/16” wrench to remove the nozzles. If you have the 12" Surface Cleaner, 14" Surface Cleaner, or the 18" Surface Cleaner, use a 1.5” wrench to remove the nozzles.
4. Using the nozzle cleaning tool, free any foreign material clogging or restricting opening of the nozzles. You can to take a sewing needle or some other like tool/gadget and clean them from the outside in. It may be hard to insert the cleaning tool due to built up debris.
5. Hold the nozzle up to light, and look through the back of the nozzle. You should see an oval or football shaped opening. If you do not see an oval, the nozzles are clogged. See picture below.

6. Flush debris out of the nozzle. Direct the flow of water through the nozzle backwards from the outside to the inside. Once you push the debris out and the tool you're using moves in and out of the hole freely, hold the spray tip to the light and look at what type of hole you see. If you do not see an oblong shape and you just see a circle opening then they're still not clean. It's an oblong hole and until you see that, they're not fully clean.
7. Attach the wand back to the surface cleaner, set the surface cleaner on a flat surface. Turn on the water (DO NOT START THE PRESSURE WASHER) and squeeze the trigger on the gun. Allow water to run through the spray bar for approximately 30 seconds.
8. Reinstall the nozzles to the spray bar and tighten securely, align the nozzle opening parallel to the spray bar.

Remember, the nozzles get blocked really easily. They are cleaning dirt, sand and soil. They take a lot of abuse. It’s important to clean the nozzles often. We recommend cleaning the nozzles out every couple of uses, if not after every use.

Pro tip: Once you have the nozzles cleaned out, you can also lubricate the shaft. That’s the component that screws into the spray bar. Use a silicone plumber's lubricant or marine grease. Avoid regular automotive grease as this wears off faster.
