Power washing is a process that involves using mechanical equipment to create a high-pressure stream of water, typically ejected from a hand-held wand or nozzle. The stream of water may be combined with detergents or other cleaning chemicals, and the pressure may be adjusted up and down. Power washing is used to clean a variety of objects and surfaces, such as vehicles, buildings, sidewalks, decks, roofs, patios, and more. It is often done by professional contractors as part of their business, and it is also widely used by homeowners who wish to clean the outside of their home or other structures.
There are several types of power washing exterior washing contractors equipment available, including electric, gas powered, and steam-generating machines. The type of machine selected depends on the specific job at hand, as well as the user’s ability and the amount of money they wish to spend. For example, a professional power washing contractor will typically use a gas-powered pressure washer, while a homeowner might opt for an electric model.
One of the most important things to remember when using a power washing system is that the extreme force of the water can cause damage if it is directed at the wrong surface or if the user is not careful. For example, it is generally not a good idea to power wash wood surfaces, as the high levels of water pressure can splinter the wood and also encourage mold growth. It is also not a good idea to power wash areas painted with lead paint, as the high level of pressure can remove the paint and expose dangerous lead particles to the surrounding environment.
The main difference between a regular pressure washer and a power washer is that power washing machines heat the water. This makes them better suited for removing particular residues, such as chewing gum from concrete or moss (the hot water helps to kill the moss and prevent it from growing back right away). It is also a good choice for areas with severe build-up of dirt, grease, or other substances that require extra force to loosen.
When using a power washing system, it is also important to follow the manufacturer’s instructions regarding the use of detergents and other cleaning products. It is also a good idea to point the spray wand away from people and property when starting up the machine, and to always use the appropriate pressure setting for the specific task at hand. Finally, it is a good idea to wear safety goggles and rubber gloves when using the machine, especially if it will be used in an enclosed area like a garage or workshop where fumes might be trapped. Thousands of injuries and even deaths are attributed to power washing accidents each year, most of which occur when people attempt to use the equipment while on ladders. Trying to control the powerful water stream and maintain balance while on a ladder is an accident waiting to happen.
