We will soon receive our Marine Blue Ford Focus II. In the family I was now commissioned with the outer cleanliness (i.e. car wash). Since the Focus is the first car where I should do something like this, I wanted to get your advice. Actually I would like to wash the dirt off the paint once a week, because the Marine Blue looks very quickly unsightly: 1. What should I wash with. Is enough water or are special cleansing agents necessary? Can the car be cumshotd and d Have air dryers, or should you wipe with the rag? 2. At what intervals should you also go to a washing machine, or do you not need it if you regularly wash at home? 3. What other external care tips do you have? Any pollitories, waxes etc. that you should apply to the appearance and durability?
