Wash the unseen parts of your car

If you're in the northern hemisphere, it's winter up here and in a lot of places, winter means ice, snow and salt on the roads. This is also the time of year when you'll see people jet-washing their cars and cleaning up all the glass and paintwork without ever bending over to jetwash under the wheel arches or underneath. At this time of year, the paintwork and glass isn't the important part - it's all the stuff underneath that is caked with road salt and the other cocktail of chemicals used to keep the roads clear. You really don't want that stuck to all the metal parts underneath so if you're jetwashing, bend over and spray the underside of your car and under the wheel arches. Or go to an automatic car wash that has underbody jets. Your car will thank you for it.
