5Fields of application and working methods
5.1 General | Effi cient high presure cleaning is achieved by following a few guide- |
| lines, combined with your own personal experience of specifi c |
| cleaning tasks. Accessories and detergents, when correctly cho- |
| sen, can increase the effi ciency of your pressure washer. Here is |
| some basic information about cleaning. |
5.1.1Detergent 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 applied from bottom to top, for example on a car bodywork, in order to avoid "super clean" areas, where the detergent collects in higher concentration and streams downwards. Let the detergent work for several minutes before rinsing but never let it dry on the surface be- ing cleaned. Note: It is important that the detergents do not dry up. Otherwise the surfac that has to be cleaned can be damaged.
5.1.2 Mechanical effect | In order to break down tough layers of dirt, additional mechanical |
| effect may be required. Special wash brushes offer this supplemen- |
| tary effect that cuts through dirt (especially by car washing). |
