Seven Things You Should Know Before You Power Wash Anything 

The use of high-pressure sprayed water to remove loose paint, mold, algae, gravel, stain, dust, gum, dirt from surfaces and items such as houses, fences, masonry, some cars and concrete or asphalt surfaces. Examples of these are  entrances or courtyards, and commonly, it is pressure washing or power washing that is used to clean these surfaces. The expressions "power washing" and "pressure washing" are often used in two distinct ways, but these are two procedures that are really extremely similar.. They both apply to an elevated pressured  water, in order to clean surfaces. However, the power washing has a heating element, which is used to warm up the water, making it more effective. .


Heated water cleans better, like any cleaning method. Substances like baking soda, vinegar, citric acid and or traditional power washing soaps, detergents, sanitizers, or disinfectants should be used as an additive for pressure or power  washing, in order to see the most difference in the surface. Before power or pressure washing anything around your home, you should know these seven tips and facts: 

  1.  Know when to power wash versus power wash

    1. Power Washer

      1. Use for large areas like long driveways, sidewalks etc. 

      2. Use where you have severe mold dust, fat, moss, weed accumulation and slick mold surfaces. The heated water here would clean dirt and grime outdoors just like the warm water is better than cold for cleaning dishes and floors. It also kills mold and moths, and keeps them from returning quickly.

    2. Pressure Washer

      1. Use in tiny courtyards, decks or driveways

      2. Use for weaker surfaces, such as decks of wood, facing and tiles.

      3. Use on surfaces such as steel, brick and concrete


  1. Know the difference between the different types of commercial cleaning solutions (detergents, solvents, etc.). 


Not all solutions for cleaning are identical. Understanding the distinction between cleaners can really be the distinction between cleaning and destruction. In power / pressure washers there are four kinds of chemicals used. These chemicals are marked according to the purpose and surface type they are designed to be used on. 


  • Cleaners remove dust and dirt, 

  • sanitizers target bacteria and are used in hygiene products (99,999% of bacteria are killed in 30 seconds or less) and 

  • disinfectants kill most, if not all, organic microorganisms in 30 minutes.


Every surface is distinct from anything else you clean. Therefore, each surface needs different techniques, nozzle sizes, pressure and, where necessary, distinct chemicals. 


  1. Know what to wash, and what not to wash.

Not all surfaces can be safely cleaned by pressure washing  inside, or around your home. You shouldn't attempt powering the surfaces or washing them by pressure: 

  • Laminar Sandstone

  • Anything painted

  • Asphalt roofing

  • Anything old

  • Stained wood


  1. The size of the surface matters. 


Since the distinction between the two techniques is primarily only heat, you should take into account the region you are going to clean, as well as the surface you are going to clean. The primary advantage of using warm water is that it is much more effective and tidy than unheated water. For bigger fields, heated water is better for cleaning. The better choice is to have a power washer if the region you are cleaning contains a lot of salt, mildew, moss or weeds.


  1. There is a difference between commercial power washers and home ones. 


If you are a hardcore Do - it-Yourselfer, consider renting a business style power washer, instead of purchasing or cleaning big regions using a home unit. Better yet, just employ an expert. Whether your unit is a home or a business unit, you can either harm the washer or you could harm the surface you are actually trying to clean. 


  1. You must learn how to be safe with power/pressure washers. 


While it may not appear to be dangerous, that thin stream of water  really is hazardous. It's up to 2,000 pounds of force from the end of the hose. It's sufficient to send you and somebody else with the strength and deadliness of a bullet with the concrete and stone chips. That is why it is important to read the instructions and make sure you are handling things properly. 


  1. Think about the time of year that you want to power/pressure wash. 

It is in the autumn or spring that most power / pressure washing takes place. Check the weather forecast if you have a couple of warm days in winter. Water is okay in warm and cool weather for cracks and crevices, but if in just a few days you expect a freeze, water can freeze and grow, damaging what you washed. Before washing, make sure the temperature won’t fall under freezing.
