For instance do you want a hot or cold water pressure washer. In most situations a cold water version is adequate but a hot water washer with an integral boiler will remove stubborn residue more easily (just think about doing the washing up – hot water is much more effective). For even more cleaning power a hot water jet washer can have a facility to make steam which is achieved by a valve reducing the water flow into the boiler causing steam to be formed when leaving the lance. Steam is useful for cleaning very stubborn deposits as well as killing bacteria.
One solution might be to hire a pressure washer before buying and ask a company expert in the field what they recommend. Don’t forget to factor in to your costings any servicing that may be required to make sure the washer will work at optimum efficiency.
Pure Water Cleaning Cleaning Equipment for Pure Water Cleaning. Water is a naturally impure liquid and these impurities can interfere when using it for cleaning as microscopic deposits can cause streaks or marks and windows for example may not look as clean as they might. Pure water has all the impurities removed by a process called reverse osmosis and because water is naturally impure it wants to return to its natural state. This means that when pure water is applied to a surface it will absorb the deposits from it leaving the surface clean and streak free.
