If you live in an area where you actually experience a winter season (we're fortunate to be in Florida), one seasonal activity you need to work into your schedule is preparing your power equipment for hibernation. Even if you plan on using it during the winter for such activities as snow and ice removal, you still have to prep the unit for storage. Read the following guide to learn how to winterize a pressure washer properly.
Many people think because they have a power washer stored in a garage or shed that it is protected from the elements. To a degree it is, but you should still winterize it. The main issue is freezing temperatures and since most garages and sheds are not well insulated, additional winterizing steps may need to be taken. The last thing you want to do is roll your power washer out in the spring and discover you have to pay for expensive unanticipated repairs. Not a lesson you want to learn the hard way.
If you think you can be bailed out by a warranty, think again. Most warranties won't cover damage caused by failing to winterize your power washer properly. We may sound like a broken record (for those of you who know what a broken record sounds like) but there's a good reason we recommend checking your owner's manual for specific information about winter storage and power washer maintenance. You want to protect your investment by following the manufacturer's winterizing tips.
You can't be too cautious when you winterize your units during cold weather. Any fluids left inside (water, oil, gas) can potentially cause problems. Water can expand and crack components such as hoses, detergent lines, manifolds etc. Oil, on the other hand, can get thick at low temperatures, and would become ineffective as a lubricant.1 Gas can gum up over time and block fuel lines and your carburetor.2 You must remember that a power washer or generator is an investment.
