For example, if you clean surfaces covered in grease with cold water pressure washer, it will eventually harden the grease and produce a waxy surface that will even be harder to remove. In fact, it will even make the job of cleaning it a lot tougher. On the other hand, if you use hot water pressure washer, the heated water will soften the grease and even melt the ones that have hardened on the surface. However, you have to remember that you shouldn t use cold water pressure washers to clean off oily or greasy deposits. Doing so will transform the grease or oily deposits in to hard and waxy clumps, which are even harder to remove. Your goal here is to soften, dissolve, and wash away grease particles easily. The Things That You Can Do With Pressure Washers If you have used power tools, such as power drills, chainsaws, and nail guns before, you know how these things can help you do the job a lot easier. With a nail gun, you will be able to hammer down nails 100 times faster than doing it with a conventional hammer. If you have a patio with a wood deck, you know how difficult it is to remove dirt as well as grease and grime caused by your grill. You can use pressure washers to clean these things but always remember that you need to be careful when working with wood and pressure washers. This is because the pressure coming out of the washer will be so powerful that it can destroy the wood if you linger too long on one area. If you plan on using the pressure washer indoors, then an electric pressure washer should be your choice. It s more expensive and less powerful than gas but it doesn t emit toxic fumes like gas powered pressure washers. But, if you want more power and you are somewhat on a tight budget and you only plan on using the pressure washer outdoors, then a gas powered pressure washer would be much more ideal for you. And, because the water is super heated, it will be able to disinfect the surface as the heat will kill bacteria and other microscopic organisms. And, if you use the hot water pressure washer in conjunction with chemical cleaners, it will even make the task of cleaning a lot easier. These are the advantages of hot water pressure washer over its conventional counterpart.
