From a distance of 15-20 cm (6-8 inch) spray a thin and even layer onto the clean surface to be treated and thoroughly wipe it with a clean, soft dry and preferably lint-free cloth. 

In case of smaller areas or close to the windscreen, apply the liquid by spraying it onto a cloth. 

If necessary, repeat the process.

Use of the various trigger sprayers: 
By turning the nozzle, the closed, spraying or spot spraying function can be set.
In case of a trigger sprayer with foaming grid: foaming grid closed: foaming; foaming grid open: normal mode.

If not used, keep the nozzle closed to avoid incidental spraying or spills.
