Gaspressure washers clear away many types of cool draft misting fans dirt and grease from hard surfaces, suchas concrete, brick, tiles, stone, metal, granite, and fiber glass. One of thebiggest problems when cleaning outdoor surfaces is the prevalence of mold,slime, and algae. Mold and slime stains often lead to discoloration that candetract from the welcoming appearance of your business. These stains can causea multitude of problems such as exposure to allergens or toxins. Gaspowered pressure washers are useful for complete removal of algae and moldsthat may appear on outdoor surfaces, such as, walls, fences, the base of aswimming pool, tiled pavements, patios, yards, roads, or walkways. Machine Specifications Thereare two main reasons you might prefer gas pressure washers over high power washers powered by electricity: Gas pressure washers can work in the absence of an electricity connection. These machines cover huge areas of ground without stopping to plug machines into the an electricity socket.

Gas pressure washers are ideal for outdoor cleaning; the fumes and engine noise they emit make them unfit for indoor use. Commercialhigh power washers are more effective than home-use power washing machines.They are more durable, with better quality parts designed to enhanceproductivity and machine life. These machines can withstand very hightemperatures and pressure levels. Many commercial water pressure washersgenerate heat up to 330°F and pressure levels of 3000 psi. Water pressurewashers can also be tri-mode machines, offering cold water, hot water, and steamtemperature options. Propanepressure washers, which can be mounted on trailers, offer the additionaladvantage of mobility. This is important if you are cleaning large surfaces,like roads, walkways, driveways, and building exteriors. Forcleaning molds, you need gas pressure washer machines with nozzles of differentsizes, starting at 0 degrees and going on to 15, 25, and 45 degrees. Lookfor a machine with a long hose. A 50-inch hose, for example, allows one toclean even semi-enclosed or indoor areas while the engine housing is parkedoutside.

If you are using a long hose, make sure the machine has a fastdisconnect mechanism that allows the operator to pause the process withouthaving to walk to the engine. How to Remove Mold and Slime Whenyou are cleaning mold, select pressure washers with appropriate pressure andtemperature levels. Concrete, brick, stone, and tiles can withstand highpressure levels, but metals may dent if the pressure is too high. Use top-to-bottomstrokes on vertical surfaces to remove mold. Similarly, on sloping surfaces,cover the upper slope first and then go downward as you clean. On levelsurfaces, clean one end first, and slowly move to the other end. This ensuresthat mold spores do not spread to the other parts of the wall or sidewalk asyou clean. Using heated water is recommended for easier removal. Remember thatif you are working on painted, enameled, and finished surfaces, minimize theuse of hot water. .
