Why should I winterize my pressure washer?

Winterizing your pressure washer protects the pump from the freezing weather during the off season months. If a pump freezes during the winter months it can harm your seals, o-rings, springs, etc. It could even crack your entire pump. Using Kärcher's Pump Guard to protect your pump from the freezing weather is the best solution.

Pump Guard is an additive that will protect your pressure washer when not in use. The Pump Guard is specially formulated to protect your pressure washer against corrosion, premature wear, freezing (-25F), and adds lubrication to valves and seals to prevent sticking. This type of care will protect your pump during the winter months. Kärcher’s environmentally friendly Pump Guard for pressure washers also helps counteract the damaging effects of every day use.
