Lastly, if you plan on buying a steam pressure washer, you may want to consider units that generate wet steam. This will ensure a more effective and efficient cleaning. As you can see, steam pressure washers are great cleaning tools that you can use. If you own a restaurant or you run a car repair shop, steam pressure washers are a must-have. 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. You find yourself wondering how you can ever remove the grime and grease without spending a lot of time or working too hard. Normally, we would treat it with harsh chemicals along with scrubbing and time consuming labor. This is the traditional way of cleaning this kind of mess and it s really not safe because of the harsh chemicals involved and it s also very hard work. Imagine doing this in a large building or areas with very long hoses. Of course, this can be very inconvenient in your part and it will waste a lot of your time. So, the best solution is to get a pressure washer with an automatic shutdown technology. It basically works just like your conventional pressure washer but this device will automatically shut off the pump when it is not in use for more than 30 seconds. With these tips, you will be able to save a lot of time and money. When using a pressure washer to wash a house, you have to start at the foundation and work your way up to the gutters. You should use a cleaning solution when washing the exterior of your house. To eliminate streaking, you should use a soapy attachment with the pressure washer. Water pressure is an important variable that you need to consider when choosing a pressure washer. Generally, pressure is rated by water pressure, which is expressed in PSI or pounds per square inch. Your garden hose delivers around 40psi where pressure washers deliver 1400 to 4000psi. You will find light, medium and heavy duty pressure washers available.
