what's the black turbo nozzle for on my greenworks gpw1804? can i use it on my wood deck?

— asked by Rob

The Turbo nozzle is for intense, concentrated cleaning on tough stains. Do not use it on your wood deck.

It produces a 0° stream, the most powerful setting. This will damage soft or delicate surfaces like wood, vinyl siding, or automotive paint.

For light cleaning on wood decks, use the 40° White nozzle. It provides a wide, gentle fan.

General guidelines:

  • 0° (Black Turbo): Stubborn stains on concrete, brick, heavy machinery. Keep moving.
  • 15° (Green): General cleaning on concrete, siding, preparation for painting.
  • 25° (White): Washing vehicles, windows, lighter cleaning.
  • 40° (White): Light cleaning on wood decks, delicate surfaces.

Always test on an inconspicuous area first.
