Usually, pressure washers are used seasonally and sit idle through the winter months. Winterizing and storing a power washer is equally as important to its maintenance as changing its oil. Proper care and maintenance are essential to keep a pressure washer performing at its peak for years to come.
Long-term storage can worsen the overlooked problems and may also lead to other problems. Common problems caused by improper winterizing include gummed up carburetors, corroded engine parts, moisture in the ignition and a lack of water pressure.
Following tips are recommended for winterizing and storing a power washer:
- Add fuel stabilize to stored and unused gasoline, so as to avoid it from degrading to the point where it is no longer combustible and prevents the gasoline from gumming up the engine.
- Flush remaining liquid from pump, for long-term storage, as it may create sediment buildup and freeze pump action.
- Treat the pump with an antifreeze product, designed to lubricate pistons and seals, prevent freeze damage and protect against mineral deposits.
- Flush nozzles and cleaning accessories, to prevent buildup which can clog these parts.
- Store in a cool, dry place. Exposure to the elements can corrode and damage pressure washer components.
