An AA/Populus survey showed only 6 per cent of car owners from professional and managerial backgrounds wash their vehicle once a week, compared with 8.5 per cent for lower-income owners.
The gap widens among those who clean their car twice a week, with 16 per cent of lower-income owners washing their vehicle fortnightly, but only 11.5 per cent of wealthier owners doing so.
