I have had an accident with an oil leek from a car on my mono block driveway.

Can anyone sugest the best way to clean it up?

I have a power washer, should i just use this? or is there an other way??

Probably not very eco-friendly & not very pretty while it's 'working' — but I find neat washing up liquid applied & left to soak for several hours works before washing off works quite effectively.

I'd be a bit wary of using a pressure washer on block paving — wouldn't it tend to remove the sand between the blocks?

before you apply anything else to it , copious amounts of petrol and a vigorous rub should remove it .

You can buy stuff to do it but my dad never had much luck with it - he uses stuff called "gunk" now.

Of course you could always turn the blocks upside down...

I have a similar problem with rust stains - any advice on this? Same sort of thing I suppose...

For oil you want a hot pressure washer really, it will just fall off. Otherwise then washing up liquid is as good as owt else.

Enzyme type cleaners get rid of oil really well.

This is not one I've used before, just the first one that came up when I searched enzyme + oil.

You just need to keep it damp to keep it active (working)

Haha,

I saw some of this in my garage last night and have done exactly that, although I haven't washed it of yet. I have left it over night and will have a go at cleaning it in an hour or 3.

Let us know how it went! Found some oil leaks on mine today and washing up liquid/scrub/pressure washer hasn't done much good.

Hasn't touched the rust stains - is swarfega likely to move these? Whilst I can stick a tray under bits of the car likely to leak oil, I can't stop the cars pooling rusty water underneath frown

Rust stains can be attacked with hydrofloric acid, also known as muruatic acid, should be available from swimming pool supply places.
It will fade then quite well....but it will also clean up the surrounding area so it may actually be just as prominent if you are not careful.
I do not suggest doing the whole driveway with acid unless you have used it before.

Perhaps a 0 degree turbo tip on the pressure washer is safersmile
(no car within 10 yards)

I think you meant Hydrochloric Acid because as much as Hydrofluoric acid would lift the stains I dont think there would be much left of your driveway!!

Hydroflouric acid reacts with very little, though would probably eat brick.

It also eats glass, about the only thing that does, and also bones. Spill some on your arm and you won't notice, it jsut seeps through skin and muscle but doesn't react. One it's turned an arm bone to a mush then you'll really know about it.

Best stick to hydrochoric.

Personally I'd just stomp some washing powder into the oilstain, damp it and wash it off a day or two later.

It will have probably faded away by the end of summer.

Swarfega did the Job,
I rubbed it in by hand and left it over night. The next morning I used a scrubbing brush and a bucket of hot water mixed with fairy liquid and then rinsed with a hose. Once the mono block had dried there was no trace of the oil.

According to the advert a thimble of Fairy washing up liquid will clean 30 years worth of greasy oven baked dishes, surely a small oil leak will be no match !!!!!!!!!!!!!

How about just replacing the bricks or moving them to another park of path/drive where they won't be noticed. Have fun

I know it's an old thread but I wanted to say a big thank you as what a life saviour it's been!

Unlike my wife, I reverse park the car in the driveway, meaning that the oil stain stretched over a couple of meters on my mono block. My technic was as follows:

1. Scrub some Swarfega over the stain, approximately 500ml/m2
2. Wait 4 hours
3. Pour some Fairy over the stain and scrub it with some very hot water
4. Rinse it

I finished it using the "Dirt Blaster" rotary nozzle of my Karcher power washer but it may not have been necessary.

The stain is nowhere to be seen! biggrin

Holy thread bump!!!

Looking for some clarification, see above people have had good results with swarfega

Now swarfega to me is the hand cleaner with the grit that gets your hands clean by taking a layer of skin off

But i see they do patio cleaners etc anyone advise on what i should be buying?

Managed to get quite a lot of ATF on it from a rack swap eek
