I do prefer to wash my stuff by hand in the nice weather but that option disappears come the fall and winter.
After hunting around google found a full service automatic car wash close enough to me, with assorted daily wash monthly plans. I chose the $20/month plan that became only $15/month with my CAA (AAA) membership. That's taxes in. I got the Plus as it does an underside rinse. https://washmycar.ca/st-catharines/exterior-car-wash/
Even if I wash my car weekly it's about $4 a shot. I can't even come close to hand washing my car in the coin bays for that small amount of money. I think the coin bays want $3-4 just to start, then look out, they demand more coins every couple of minutes it seems.
How do you take care of your car's exterior in the winter?
Coin bays? Automatic washes? You have your own facility in your garage? You do nothing and close your eyes to the mess your car becomes?
