After a number of drive through car wash's over the years tonight I have decided after a lot of crappy results that Shell Car wash's amaze me every time at the finished product.
So what harmful chemicals are in there wash? as others dont come close imo.
What's your favourite drive through car wash ? Mr Suds or even those summer cheerleader fund raisers where 20 people washing still seem to miss spots in the middle of the door.
And yes I know you can't beat the good old hose and bucket in the driveway or fording a swollen river for those die hard.

For automatic car washes I've always liked the car wash at the Petro-Can at the bottom of Cap road in North Van. It works so well that it tore off a loose rocker panel once.

My favorite when the weather allows is my pressure washer. Even though it’s an electric Canadian Tire model, it still cleans the undercarriage better then anything else I’ve used.
