I always try to keep the cars clean. I'm not too much a detailing addict but at least I try to put twice a year a good wax on top. If this is done it is enought to run through an soft-wash machine and take a microfiber towel afterwards for final dry up work. It takes less than 15 minutes (including the waiting line) - so I can do this normally every other week once with each car (whenever I pass by at the car wash - wouldn't go there just for this). 

I'm just to addicted to cars to not having them clean. I dont like dirty cars as I dont like a dirty home - so I have to clean it ;)

But for sure - the older I get the less cleaning addict I am! Especially, since having our baby girl I got a lot more relaxed (otherwise I probably would have to kill myself) lol
