hey dude, I am just stating the fact that what you have
mentioned has got nothing to do with grooming, but rather cleaning.
Those $450 session or package that you mentioned are definitely
different from what you are doing all together, so I think it is
important that you get your facts right before trying to preach
about grooming here.
I think it is a waste of unnecessary time and money, and
burning off excessive fuel to let the engine run while you clean
your car.
Btw, where do you usually throw all those wet tissue after you
clean your car in the morning and evening? You just dump it at the
car park right? litter bug!!
