There are a lot of good reasons for using a self car wash instead of an auto crash. First of all, you get to wash and rinse your own vehicle. This is a more convenient way to go about doing your vehicle maintenance. Instead of having to get in line and wait for a technician, your self-wash will let you wash your own car. A self-service carwash also differs from an auto car wash system in that you only need to do the rinsing and washing yourself.
A self car wash also differs from an auto crash in that you can manage to get the washing done on a much more regular schedule. Most auto car washes are only done on a daily basis, which is already very hectic for many people. With a self car wash, you can set up your times to do the rinsing on certain days such as Saturday, Sundays, or any other day that you want to. So, this way you don't have to worry about cleaning your car on a very odd schedule.
