“Which detergent should I use for Greenworks 1900 psi model number 5119102/GPW1900?”

1-2 of 2 Answers

• Since I just use it to wash my cars, so I use generic car wash detergents. I'd contact the Greenworks support team if I plan to wash the driveway or Garage floor. I hope it helps.

• Hi Dia. Thank you for your question. You can use any generic pressure washer-safe detergent purchased at your local hardware store such as lowes. Do not use any corrosive products like bleach, alkaline, ammonia, wax, or alcohol.
