Hot Water Power Washing
What's the difference?
All pressure washers are not created equal. In fact pressure cleaning systems tend to fall into two very distinct categories: hot water pressure washers & cold water pressure washers.
Because both hot and cold water pressure washers have models with the same flow rate, the same pressure and the same capability of cleaning indoors or outdoors, it begs the question: How do I choose between a hot water pressure washer and a cold water pressure washer when everything else is relatively the same?
The rule of thumb is simple: whatever cold water cleans, hot water will clean better and faster.
Hot Water Pressure Washers…
Hot water packs a powerful energetic punch when released into the cleaning equation. This energy also causes a reduction in the water’s surface tension allowing it to easily and more effectively penetrate the molecules of grease and grime.
Actually, there are three key elements to a hot water pressure washer —heat, agitation and soap—that successfully remove grease and grime. Here’s how they work:
- Heat, as described above, creates a high-speed molecular action that causes the cleaning agent to be more active and reduces water’s surface tension so it can effectively penetrate grime at the molecular level.
- Agitation is the impact that comes from the water volume and water pressure hitting the surface—similar to the action of hand scrubbing the dinner plate in your kitchen sink.
- Soap (often referred to by pressure washer users as “detergent”) chemically breaks the bond between dirt and the surface. It starts when the molecules of oil and grease attach themselves to dirt and keep them trapped or bound to the surface. Detergents use softening agents, technically referred to as “surfactants” (an abbreviation for “surface active reagents”) to emulsify the oil and grease—this is the process in which two or more immiscible liquids, like oil and water, no longer repel each other but actually mix. Once the oil and water are able to mix forming an emulsion, the dirt—still clinging to the oil and grease—is carried away in the wash water.
So what does all of this have to do with a hot water pressure washer?
Hot water pressure washers bring together a perfect balance of all three of these key elements—heat, agitation and soap—to deliver a pressure cleaning knockout punch.
What NOT to do
The first thing people think of when they want their house cleaned is to have it pressure washed, but the surfaces on the exterior of your home are not made to withstand the destructive forces of high pressure water being sprayed only inches away. Paint can be blasted off, screens can be shredded, and more.
Every year thousands are injured nationwide attempting to clean their own homes. The number one cause of these incidences occur while pressure washing homes or other structures from a ladder. A misconception that most people believe, despite all the risk involved, is that they have to get close enough to the surface they are cleaning to blast the dirt and grime away with high pressure.
And besides the damage and the risk, leaving this type of cleaning to a DIY project, or a nonprofessional, can leave you with unsightly "tiger striping" and uneven streaks.
