What do I use a pressure washer for?
There are lots of applications for both homeowners and industrial needs–cleaning driveways, buses, buildings, heavy equipment, you name it. A pressure washer does exactly what it says: it uses pressure to wash, saving you hours of time and effort. Pressurized water on its own is a powerful cleaning tool; combined with the right detergent, the results can be amazing. A good quality pressure washer is one of the most versatile and productive tools you can own.
Do I need a cold water pressure washer or a hot water pressure washer? What’s the difference?
For simple, infrequent jobs, the kind most homeowners tackle, a cold water unit is fine. A machine that puts out 1,500 psi (pounds per square inch) at 3 or 4 gallons of water per minute will do an acceptable job of cleaning mildew off your deck or dirt off your sidewalk. If you’re trying to remove any kind of oil or grease, though, you definitely need hot water to accomplish that. If you pressure clean frequently, or if your needs include those heavier-duty jobs, going with a hot water washer will make your life easier in the long run.
I can get a pressure cleaner at my local home improvement store for just a couple hundred bucks. Won’t that do what I need?
Those are cold water pressure cleaners, so they won’t be able to remove any oil or grease-based stains or residue. They’re also not built to tackle heavy-duty jobs. If you plan to use your pressure cleaner on a frequent basis or for an extended period of time, you’ll save money in the long run by buying a better quality machine.
You mentioned PSI–pounds per square inch. What’s GPM–and which is more important?
GPM is gallons per minute. Which is most important depends on your task. If you’re trying to wash away heavy dirt, GPM will be more significant. If your problem is stubborn, residual grime, then PSI is the more important factor. If you’ll tell us what you’re trying to clean, we’ll be glad to help you figure out the best machine for the job.
