STIHL Pump Conditioner and Winterizer

The STIHL pump conditioner and winterizer protects your pressure washer against freezing for safe storage in cold weather. This product comes in a 16 oz. bottle and is designed for use with all STIHL pressure washers to prevent harmful build-up of hard water mineral deposits in the pump. It also preserves seals and pistons and is great for cold weather and extended storage.

PRECAUTIONARY MEASURES: Make sure the engine switch is in the OFF position and disconnect all pressure washer hoses. Pull the rope when squeezing the conditioner and winterizer to help flush the fluid through the entire pump.
