If money permits or beg, borrow a leaf blower. They can be as cheap or as expensive as you like but try and get one of a manageable size so that once you`ve given your motor a good wash, instead of dry toweling or chamioing it use the blower as it makes easy work of drying. It also gets all the remaining water out from the nooks and cranies that spoil things when you drive off and have water marks all down the sides.
