I forgot to add that these guys also do something else in the parking lots.

They spread a "Special Powder" that "eats Oil". A "nematoad" type stuff. Every parking space in front of a strip mall or bowling alley or movie house or coffee shop or drive-in or gas station or bank drive-thru or where ever vehicles sit....has OIL drippings.

A 5-minute demo of spreading this Special Powder convinces the space manager of the need for this "Oil-Removal Service".

However....just starting out...go visit the people who are in charge of the parking lots and see what they will pay for "Clean-Up"...either nightly, 2 or 3 times a week or weekly.
