HG Tile and Natural Stone Oil and Grease Absorber 42, Removes Oily & Greasy Stains, for Stone & Porous Stone-like Surfaces, Indoors or Outdoors, Safe & Effective for All Floors – 250ml (470030106)

I had a few small petrol and oil stains on my Indian Stone driveway which I had chosen not to seal to keep its natural appearance.I tried all sorts of different patio and driveway cleaners without success, including oxalic acid crystals but the stains remained.After reading all the reviews I bought this product.It is a grease like paste that you smear over the affected area and leave for a minimum of 4 hours. In that time it shrinks and dries leaving a white paper thin crust.Low and behold it worked and the stains are now gone.Really pleased with it.I washed the stain areas with a cloth and water after. In one area there is a very slight shadow left and the instructions say apply another coat but it is hardly noticeable so I won’t bother.I bought a small tin which was more than sufficient for what I needed but if you have numerous stains or a large area to cover then go for a bigger size although I know it is quite expensive.

Having a small oil leak from the car I ended up with oil on the driveway over a long period of time, so thoroughly soaked in to the un-sealed concrete. I first tried Gunk driveway oil cleaner. All that did was clean off around the oil leaving the oil untouched (See picture) so I Checked out the reviews for this item. Had to wait for a few days for some dry weather but give it a go. .The product is the consistency of gunge and it doesn’t look very appealing, but hey it’s to clean oil so who cares.Stirred it up and applied as per instructions. Petty simple to do. Left it for they time they suggested and it turned white as they say. It was quite a hard substance so you need more than just a brush (probably a wire brush) but I washed it off with water and a brush.The results are pretty good in my opinion. Not perfect but a whole lot better than using gunk which didn’t do anything to the stain. I think a wire brush may do a better job of removing the crust intact so may do better at keeping the stain out.I recon a second go will pull out more and I have a little left so may well give it a go at the next sunny weekend and follow up with a jet wash.Conclusion: it works, be prepared to Give it more than one attempt, but worth the cost.

I have a shared yard out the back with york flag stones from 1820. My neighbour decided to pour chip fat onto them to avoid blocking the drains, which looked awful! I ordered this after reading the reviews. It arrived quickly but I was suprised how small the tin was and knew I would not have enough. I tried it anyway on the stone on 'my side'. It dried to a white powder. Very smelly in the process like paint thinners but as I was working outside this did not bother me. After a few hours I brushed it off with a scrubbing brush. It left some white residue but I washed this off with a hose really easily. Once dried I could see it worked - it had removed the oil stains from the stone. Neighbouring stone was still stained so a good comparision. I would have loved to have used this on the hole area, but would need quite a few tins so nature will just have to fade the rest. Turps, patio cleaner and metholated spirits failed to do what this product did achieve - so its brilliant. Best for a small area. Highly recommend.

I purchased this after reading the many positive reviews on Amazon. I was trying to remove some staining on my sandstone patio caused by teak oil. It is not a dark stain like engine oil, it look more like grease so I was quite hopeful. I followed the instructions to the letter, stirred well and applied the recommended thickness of 0.5cm. After leaving on for just under 5 hours I was excited to remove the crust. However, I was dismayed to see absolutely no difference at all! I contacted the manufacturer who replied by re-iterating the usage instructions and suggesting that more than one treatment may be necessary. Had I seen any reduction in the stain I may have been tempted to buy some more and re-treat. However it's an expensive product as you only get 250ml and that really doesn't go very far when you are applying 0.5cm thickness. So I am not going to throw good money after bad and will look for something else. This product may well work for you and clearly has for others, but for my stain it was a complete waste of time and money.

Bought this for some old oil/fuel stains on our driveway. There is only 250ml of it and it doesn't go far of you apply it according to the instructions.It clearly states that it doesn't do well on old stains, which ours were so we weren't expecting miracles. It did OK, reduced them somewhat but still very visible, we are now going down the acid route instead.Can't vouch for how this does on fresh stains, perhaps it works wonders?
