Efficency Debate
You know how when you go to the automatic car wash, you often get a “pre-soak” where they drip soapy water on your car and let it soak in for about 20 seconds?
That pre-soak lead me to wonder–would an automatic car wash get your car cleaner if you went when it was raining. If a pre soak does anything at all, then I would think that your car already being wet from the rain would help soak the grime off.
Any argument as to why this would not be so?
