I recently performed a parking lot was for a small business that has not had any service performed over the past several years (at least 5-10) The parking lot has several parking places with heavy oil staining that has set in over time. I SC'd the entire lot with hot water (230) and then went back and treated the stains with degreasers such as Magnum K and Clean Xtreme to try to lift the oil out. I am not sure if my expectations are unrealistic as I do not have much experience with oil removal or if my chemicals are sub par but I am not seeing the results I would like. The customer seems happy but I would really like to "WOW" him. Here are a couple of pics to give you an idea. Also I have searched through the forum and found varying advice and recommendations but is EBC really a "cure all" for these type of stains or is it more about a multi treatment process that takes several days?

Thanks in advance for the help, Austin

 
I definitely hit on the benefits of regular maintenance, which he interpreted as once a year, until I further explained how much better his storefront would look done on a quarterly or even biannual basis. Hopefully the landlord feels the same way.
 
Put your soap on straight, first, while it's dry and don't clean until it has 'ate' all the way through the stain.
