Prevent moisture in the car in winter
The following tip, so that in winter the inner panes in the car are not so easily start by moisture or freeze.
Place a sheet of newspaper under the floor mats (ATTENTION: older mats may slip slightly at the beginning). This absorbs moisture from shoes and clothing. Thus, the discs in the interior can not start so easily, or freeze.
PLEASE NOTE: Regularly change the paper, otherwise it will not help. I've been doing this for a few years, works great.
