- the preparation of the agents used according to the invention offers no special features and generally does not require any particular order when mixing the Components. If the soap provided in the funds first of all from fatty acid and alkali is to be formed, this is conveniently done in one Part of the water before adding the other ingredients. In the event that none pre-emulsified waxes are used, it is for pressure emulsification It is advisable to put the alkalis in water.
- the cleaning agents are usually undiluted or only slightly diluted with water on the plastic surfaces applied as evenly as possible.
- the wetting of the surfaces will preferably by spraying the cleaning agent in liquid or pre-foamed Form, for example with the help of a spray gun.
- Another Possibility is to use a cloth or an absorbent article, for example a sponge to soak with the cleaning liquid and then with to treat this object the plastic surface.
- the cloth is then wrung out from time to time if necessary, rinsed with water or new cleaning fluid and again used to treat the plastic surface. Rinsing the Plastic surface with water is not necessary and on the contrary can affect the effect achieved according to the invention rather disadvantageously.
