Granite is so dense, i would assume the oil hasn't travelled very far into the block. Maybe try your normal oil remover with some decent dwell times?

They would probably be 10mm of granite with the rest concrete cast, granite faced blocks... just letting you know... whether or not it makes a difference to the way you get rid of the stain I do not know

I'm no expert on oil removal and I say it like many others, I haven't mastered it but I've tried alsorts on the very same surface and had no joy.

In my opinion that can't be removed. But I'm no expert in oil/fuel stain removal.

I have never got oil out of any surface. Working with Lee on Saturday there was some oil all over the sandstone. I said that the slabs would want lifting and replacing. I know if I had paid for the slabs to go down I wouldn't settle for oil all over them.

Chris

Look at proper poultices -wall paper paste free ones ;D, proper dwell times etc but promise nothing

Good luck

Rob ;D

What about those bio oil cleaners that you can get? they contain active enymes that feed on oil, right into the paving and die off once all the oil has been devoured... same thing as they use in oil spills in the sea, I believe oil technics do one and there is another company that do one, can't remmeber the name.
You could put it down, leave it for  few days then return?

WonderMicrobes is a multi-culture concentrate available in liquid form. It is composed of at least twelve select microbial cultures and enzymes designed to bioremediate almost all fractions of crude or modified petroleum products and paraffin wax. They are also effective on animal and vegetable oils and fats.

Powerful soaps in WonderMicrobes break the hydrocarbons into minute molecules. The microbes then attach themselves to the contaminants and reduce them to carbon dioxide and water. The microbial cultures continue enzyme production until all oil contaminants and other organic wastes are consumed. WonderMicrobes is non-toxic, non-caustic, non-corrosive, non-pathogenic (harmless) and is biodegradable.

Application

WonderMicrobes effectively removes surface and embedded stains from spilled petroleum products on concrete and asphalt garage floors, driveways, shop floors, loading docks, fueling areas, parking lots and oil storage areas. It inoculates the contaminants with bacterial cells and oxygen catalysts necessary for complete biodegradation. This formula can also be used for washing soil, sand, gravel and loose rocks and for cleaning heavy machinery.

Equally successful for light petroleum, lubricating oil, gasoline, kerosene and diesel spills
Effective for cleaning cooking oils and fats including grease trap maintenance.
Shortens clean-up times for oil spills and stains
Cleans oily equipment, vehicles, tools, floors, stoves, cabinets and carpets.
Cleans up spills from hydraulic brake lines and equipment failures
Contains no petroleum distillates or solvents
Contains essential microbial nutrients and oxygen catalysts
Enhances biodegradation above and below ground surface, when used as recommended.
Economical and ecologically sound
Eliminate removal and replacement of contaminated materials
Properties

   pH 7.0 - 8.0
Instructions

Shake or mix thoroughly before dispensing.

Hard Surface Cleaning: Dampen the contaminated surface, apply WonderMicrobes and allow it to work for 20 -30 minutes, then brush and rinse. Keep the work site damp during treatment and repeat if necessary.

Porous Surface Cleaning: Scrape surface, dampen and apply product. Leave on the surface a minimum 2-3 hours. Use burlap cloth or similar breathable moisture holding covering if longer periods of time are necessary. Scrub the surface periodically if dirt is heavily compacted. Rinse.

For soil remediation: Apply 1.0 gallons per cubic yard of soil to be treated. Soak the soil thoroughly after application. Keep soil damp during remediation which may take several weeks. Air tubes inserted into the ground for deeper contamination will accelerate rate of bioremdiation.

Tank Cleaning: Dilute 1:3 and apply by sprayer. Leave on the surface for 10 - 15 minutes, to allow penetration, and remove with a pressure washer (use dechlorinated water). 1 gallon of concentrate should treat 100+ feet of tank surface.
Tanks that have larger quantities of remaining hydrocarbons should be filled with water and aerated during remediation period.

Precautions/Limitations: Read and follow precautions on MSDS. Pretest new equipment finishes by applying to a small area first. Optimal performance is on damp concrete surfaces.

Dilutions:

Full-strength - heavy aged oil stains (wet the surface with water before applying. Follow first application with diluted product for better activity)
1:3 - tool cleanup and parts cleanup
1:5 fresh oil stains
Storage

WonderMicrobes should be stored between 10º-40ºC (50º-104ºF). Avoid prolonged exposure to higher temperatures. Keep from freezing.

Just got to find a supplier now ;D

Has anyone ever tried these type of cleaners? would be interested to know, got a oil stain on a job that has been there over a month, it's on bright white concrete cast flags (I know, probably the worst surface it could be one, sticks out like a sore thumb) and I was thinking about using this type of cleaner, read lot's about them but never tried them.

Im going to do an oil clean up today. Oil filter housing has leaked on a cement slabbed drive. i use a product called OT8 which works on the enzyme principal.

 http://www.oiltechnics.co.uk/Oil_Stains/BlockDrives/OT8.html

it has worked for me well in the past using it on monoblock so ill see how it goes today.
