Cleaning Oil off concrete/ pebble coat

[Barefoot Dave]

Well, after considerable searching, it appears we don't have a specific thread on the best methods for removing P.O.L from various parking surfaces (without the destruction of same):Thump:
Could have sworn this was a LandRover forum ; )
So, hit me please.
We have ~8yo pebble coat, concrete base driveway with 3 yrs accumulation of various fluids that needs cleaning. Have tested;
Kenco HD Degreaser: 1hrs and overnight, scrubbed then washed off
MAF cleaner: " "
Gel bleach: " "
Napisan (dampened): " " (a small lightening of colour after 1 hour)
Enzyme type laundry Liquid: " "
(1:10 diluted for coverage)
30sec cleaner: " "
WD40: " "
Pressure cleaner (140psi@ 20DegC)

Still no joy.
Help, Please.

Bare concrete: ?
Coated Concrete: ?
Pebble coating:
Asphalt: ?

You might be lucky to remove it as soon as it is dropped and is clean oil but anything else is a lost cause, particularly if it is used diesel oil and has soaked into the concrete.

I have found the best is to clean it as best you can and then leave the sun to do its job. Microscopic bugs can eat oil and they thrive in full sunlight. I have found that after a year of sun exposure most of my stains slowly disappear but I keep on dropping more.

a good bleaching washing detergent, some water and a bristle brush.

Bio Diesel... It dissolves Mineral Oil

Or acid etc the entire area....

I tried a product called "Lanotec Citr-Force" . I applied it 'neat' as a flood coat on an area about a foot square and rubbed it in with a floor scrubbing brush. left it for 10 minutes then attacked it with a pressure cleaner (about a 12 bar one ) Do it when the temp is about 25 deg and not in the sun (this is important). Also you need to be careful with pebblecrete not to physically dislodge the surface. A lot of the stuff came to the surface and washed away. let the summer sun do its bit then tried again after a month...same routine. It's not perfect but a lot cleaner.

I also discovered this citrus stuff is great for getting rid of handmark grease on internal stair railings, fat/oil from range hoods etc without softening the paint which can happen with the "spray & wipe" formulations sold in supermarkets:mad:

BTW it's magic for getting grease of your hands after working on the LR...smells nice too:eek::p:

My pick - Chemtech CT14 ( Now called bilge cleaner of all things). Available at supercheap et al. Use just like Mr Hoges Lanotec -again, it won't make the stains disappear, but it will suck up a fair amount of oil ( Is more alkaline than kenco - use safety glasses).

You want to be careful what you use, I used CLR, supposed to clean all. Trouble is if there is cement or lime involved it eats that as well, used on my shower floor and a week later all the tiles and grout came off, so check what your using doesn't dissolve concrete, BTW it got the stains off, Regards Frank.

CLR is not product for oil - CLR is only good for Calcium, Lime and Rust (CLR) hence the reason it chews concrete - calcuim and lime a main constituent.

Ask someone for a 20L drum of used diesel engine oil, brush carefully over the whole surface, wash desultorily, you have a uniform black colour.:wasntme:

WE HAVE A WINNER!!!:twisted:

[It'sNotWorthComplaining!]

If everything Else Fails then Get one of those signs that says.
"Parking for land rovers only, all others will be towed away."
then if any one spots the oil, they'll know it's meant to be there;)
