Hello BobbieP.

Thank you for choosing Greenworks Tools. We would love to hear what you think of the Greenworks 1900 PSI pressure washer when you have a chance to use it a few times. In the meantime here are some tips we'd like to share with you to ensure longevity of the unit.
If the pressure washer is subjected to freezing temperatures or is to be stored or left unused for ANY period longer than thirty days, the unit should be stored properly. This is called “winterizing”. The term is somewhat confusing because your storage period may or may not happen in cold temperatures or even during winter. Nevertheless, this procedure is strongly recommended to be done every time the unit may sit for longer than thirty days without being used. Whether stored inside or out, heated space or cold, winter or summer. This keeps the unit from freezing and, very importantly, it keeps water from drying out inside the pump and leaving behind very harmful deposits. These deposits will act like sandpaper in the seals the next time it is used and could damage a piece of the brass. This also keeps any parts from rusting or oxidizing which may destroy your pump. We hope this information has been helpful and we look forward to reading your review soon!
