NEPTUNE PE
5 Applications and methods
5.1 | Techniques | Effi cient high pressure cleaning is achieved by following a few |
|
| guidelines, combined with your own personal experience of specific |
|
| cleaning tasks. Accessories and detergents, when correctly chosen, |
|
| can increase the efficiency of your pressure washer. Here is some |
|
| basic information about cleaning. |
5.1.1 | Soaking | Encrusted or thick layers of dirt can be loosened or softened up by a |
|
| period of soaking. This is for example an ideal method within agricul- |
|
| ture – for example, within pig sties. The ideal soaking method can be |
|
| achieved by using foam or simple alkaline detergent. Let the product |
|
| lie on the dirty surfaces for about 30 minutes before pressure wash- |
|
| ing. The result will be a much quicker high pressure cleaning proc- |
|
| ess. |
5.1.2Detergent and Foam Foam or detergent should be applied onto dry surfaces so that the chemical product is in direct contact with the dirt. Detergents are ap- plied from bottom to top, for example on a automobile bodywork, in order to avoid “super clean” areas, where the detergent may collect in higher concentrations and streams downwards. Let the detergent work for several minutes before rinsing before rinsing and never let it dry on the surface being cleaned.
5.1.3 | Temperature | Detergents are more effective at higher temperatures. Greases, oils |
|
| and fats can be broken down more effectively at higher tempera- |
|
| tures also. Proteins can be cleaned at temperatures of around 60°C |
|
| (140°F). Oils and traffi c fi lm around 70°C (158°F), and grease can |
|
| be cleaned at |
5.1.4 | Mechanical Effect | In order to break down tough layers of dirt, additional mechanical |
|
| effect may be required. Special lances and rotary or wash brushes |
|
| offer this supplementary effect that cuts through dirt. |
5.1.5High Water Flow or High Pressure
High pressure is not always the best solution and may also damage surfaces. The cleaning effect also depends upon water fl ow. Pres- sure levels of around 100 bar (1450 psi) may be suffi cient for vehicle cleaning (in association with hot water) and higher flow levels give the ability to rinse and flush away large amounts of dirt easily.
