The prevention of sulfur, dirt, and mildew buildup on the exterior walls of your property, or even the roof, calls for routine maintenance. But this maintenance is not just any kind of maintenance. Pressure cleaning is often what is needed to remove mineral deposits, tree sap, phosphate, dirt, grime, and more.
Pressure cleaning, also known as 'pressure washing,' utilizes high pressure water and power detergents to remove these unpleasant markings. You can find this kind of stuff where sprinklers hit the outside of your home, on your roof, on pool decks, outdoor patios, and more. If there are surfaces that are uneven or textured (textured pool decks especially), you'll notice these areas are a lot more prone to this type of thing.
Pressure cleaning is something you can either do yourself or hire a professional to do routinely. Every few months you should either clean these surfaces or hire a pressure cleaning professional to clean. It's a relatively inexpensive service and shouldn't take long to do, depending on how large the surface area is that you're cleaning.
You can also do it yourself by purchasing a pressure cleaner or by renting one. You can find very small, inexpensive electric pressure washers to clean small areas and easy maneuverability, or large, dual fuel, gasoline-powered pressure cleaners for large surface areas. It all depends on what you need to clean, how frequently you anticipate washing the surface or surfaces, and how much you can afford to invest in a pressure cleaner.
You can find a high quality device at a good price by searching online or going to your nearest home goods store. You can also order parts and detergent online. Be sure to read your owner's manual to determine what type of cleaning solution you should use depending on the surface and pressure washer specifications.
For electric pressure washers, be very careful any time you have to use a plug-in device. You cannot get the chord or outlet wet, and if you do, you risk the danger of electrocution or even death. Always follow your users' manual.
