before winter gets here i usually throw a few good coats of wax on to get me through the winter, then during winter i try and take it to the self serve wash once a week to spray under the wheel wells and under the car the best i can. i dont use their soap though, it always seems to strip my wax whenever i use it. but then when spring comes i spend about a full day cleaning and treating it back to pre winter condition. but with winter the way its been who knows when spring will be here lol
