This really has nothing to do with driving, but we want to make sure that your car aesthetically continues the look the best it can. You know all that salt and grime that builds up in the snow? That gook is detrimental to your paint job, and if you don't remove it, damage will be done. We recommend finding a drive-through car wash that you can trust (ask around and use reviews to avoid washes that'll scratch your car), buying a monthly pass, and using the hell of out it. Unless you want to be outside washing it in the cold. We've done that, too.
