I spilled a bit of (used) engine oil when I serviced the Mondeo the other week. I put some sand down to mop up the oil which worked a treat, but it's left an unsightly stain about 8" x 3" which I would like to get rid of or at least fade a bit.
Well, I can then speak from very recent (last week) experience.
My two year old driveway is surfaced entirely with light duty tarmac and after (a) a discovering that some workmen's Transit van had leaked oil, (b) degreasing my motorcycle chain in situ, (c) washing off the rest of the filth from the bike after a very wet riding holiday, the tarmac was very stained over a wide area.
I had a bottle of Jeyes driveway cleaner (not the same as Jeyes fluid) and it made no mention of not being suitable for tarmac, so I tried it.
Used in recommended concentration it made not a jot of difference, so I tried again, neat, on a test area. After scrubbing it with a broom and leaving for a few minutes I hosed it off (I don't have a hosepipe ban to worry about) and then pressure washed it from a distance of about 12" with an oscillating wand.
The result was clean, undamaged, tarmac so I did the rest; perfect. Looks great, though I wouldn't want to risk making it a regular event.
washing powder i.e. the stuff you wash your clothes with............pour it over the affected area and allow it to well soak in, overnight if you can.... then remove the soaked in granules, before scrubbing the residue off with hot water.
worked a treat for me...... (but on concrete though)........ when the dog trod on the bowl i had filled with old sump oil and spilt the whole lot down the drive......... i could have murdered the sodding thing, safe in the knowledge it was really my fault for not picking it up quicker
hang on a minute .you use all the above chemicals to dissolve a small oil stain then power wash them away .,to where ?down the drain perhaps ,do you think that its ok to add to the polution by adding more chemicals?
I have always used Fairy Liquid and had good results. My method is to pour it neat onto the stain (works well on both concrete and paving blocks) and then rub it in using fingers. Leave for the rain to wash it away so as to give the FL plenty of time to soak in.
Tarmac drive? Never use a solvent anything like Gunk as it equally efficiently removes the binder material holding the stones together. Yes, the stain goes but along with the section of drive. Probably strong detergent followed by a bit of weathering is the best option.
I always use washing powder or soda crystals (not to be confused with caustic soda) just sprinke over the stain until it looks like a thin covering of snow, and leave it until the weather gets rid of it. Works a treat on both concrete and tarmacadam.
One thing you have to consider is that tarmac is basically stones held together by a very heavy oil. To remove oil stains I would recomend something that clears away light oil stains, or else your drive my suffer.
French chalk is, (or was), used in bicycle puncture repair.
It is sprinkled on the patch area, (over the excess glue), to stop the tube sticking to the casing.
However, the quantity supplied, in puncture repair kits, is very small and it usually requires grating to make the powder.
Try bicycle wholesalers?
Pal of mine repaired trucks. Had a break-in one night. Scrote came through roof, onto roof of truck and the dropped to the floor. In the morning pal opened up and found two expensive trainers drenched in sump oil and his drain tray half empty. I don't think he managed get the oil off to use them himself ! Good result though !
what you need to do is wait till your sat watching TV with SWMBO and say 'you know even though your a genius with the housework...even you could'nt clean that oil off the driveway' by the time you get home from work the next day it will be spotless only downside is a very smug missus for a few days
My neighbour has a ten year old station run 3 series that has a persistent oil leak. He's been told it's too expensive to fix so it sits parked in the road dribbling oil (you can see a long string of the stuff hanging down most days) and he puts a few litres in each week.
Consequently the patch of road outside his house is looking a bit Amoco Cadizy - I fully expect to see a blackened cormorant flapping around in it sooner or later.
Anyway, what happened to the bacteria that I seem to remember were available for "eating" oil?
I'd suggest trying out OIL GONE EASY HOME & DRIVEWAY S-200. I tried this product to remove oil stains in my driveway and the result was just amazing! It was as if there had never been a stain in the first place. Not only does this work well it also does not require any cleanup like other products that I've used in the past.
