I just purchased my first car here! Where's the best place to wash it or buy the car wash stuff for me to wash myself? Thanks!
A lot of gas stations also have a car wash. I use one at the Eneos station near my home. Just look around and you should find a car wash.
Just wash yourself at home. There are auto stores around if you want cleaning supplies - you can use auto bacs or other shop.
Another car shop is called Yellow Hat.
