I'm sure it's been discussed but doesn't anyone use those hand-wash places where you drive in and sit there whilst they pressure wash, and then get out and watch whilst they do the interior?
I'm sure they are frowned upon by people who spend 2-3 hours washing and waxing their cars, but it's not practical where I am (don't have an outside tap on the rented house, for a start). I've been using them for years and never had issues.
This is like coming into a healthy eating thread and talking about how you’ve enjoyed eating greasy donners for the past few years.
