WHEN it comes to washing cars, Scottish drivers are squeaky clean.

As many as 60% of Scots clean their cars at least once a month - the best rate in the UK - a survey by car wash company IMO showed.

In contrast, only 45% of motorists in southern England give their vehicle a monthly wash, below the national average of 49%.

Women worry less about their car's appearance than men, with only 44% of female drivers washing their car monthly against 52% of men. Car owners in northern England were least bothered about what others thought of them, with only 35% cleaning their cars to make a good impression on others.
