What do you guys use to remove old diesel oil stains from concrete? I have tried a few things without success.

[Spud_133]

A hot pressure washer?

[Yoda]

What have you tried so far? a lot of commercial products simply dont work.

 

Old school methods usually work well though. Try dusting a heavyish layer of washing powder on it. leave overnight and then pressure wash the area off. If that dont work, either washing powder made into a thickish paste with water or washing up liquid, then use either product with a stiff brush to scrub the area, leave ovenight and pressure wash.

 

one of these methods should work for you.

 

I am suprised you didnt know the answer to this considering you owned a garage for how many years?

 

LOL

Oven cleaner sometimes does the job too, if its really stubborn. Mind you dont get it on your skin, rinse well with a watering can after about half an hour and then pressure wash. (do you see the common factor yet? yes pressure wash!) as long as you use some form of strong detergent, the pressure washer will lift the stain easily.

We had nice shiny painted floors that wiped clean, I have tried many chemicals but do not have a pressure washer.....well that's a lie, I bought a top o the range Bosch washer that never got used for 18 months and when I did it was broken and could not get a warranty replacement so I guess I better not be so tight and buy another

On Sunday morning, open your window and amongst the noise of lawn mowers, you will hear a neighbour washing his car with a pressure washer! go talk him into doing you a favour!

Some white spirit should help to move it followed by some decent soap / detergent. Either use an old wire brush or heavy duty broom to scrub it in then as and when you get a power washer rinse it off.

Have you tried engine degreaser? squirt some onto the area, leave it for a minute or 2 then scrub it in with a stiff brush then rinse it off.

I tried lots and in the end I put down cement and brushed it about which lifted it up out the concrete which is porous, and when it was lifted I sprayed a drop of water down and brushed it about for a cement wash when dry the drive is like new and never came back .

Cement, salt, fullers earth.  Anything porous and absorbent and dryer than the stained concrete.  Salt is excellent for getting WD40 or Sillicone out of church floors.  Pressure washer alone now won't do much, it'll take off some but it may push some of the oil further into the concrete and make it harder to remove.  I use a lot of leaky and oily equipment in ancient buildings, I've done this more often than I would like.

Dishwasher tablets ground up work brilliantly, if you need to make it into a paste use washing up liquid.

I was going to suggest the same...   

 

Went round to a mates to pick him up in the mini. He was jet-washing his bike at the time and i asked if I could use the jet-wash under my bonnet because my radiator had developed a leak and got orange stains everywhere. 

''I've got something even better'' he said. Some industrial engine degreaser (designed to be watered down) sprayed on neat, made my engine bay look 10-years younger, and now his drive way has a lovely clean patch that sticks out a mile! 



Going to ask if he can get me some more from his work, because my mum, an my girlfriends mum keep moaning about the oil stains I leave
