It works for me though. Other things like Gunk and Jizer you can use to clean off engine oil will melt your tarmac unless you rinse them away soonish. Diesel melts tarmac but petrol is not too bad. I think Petrol evaporates before it does much damage but diesel does not evaporate as for ages as it is more of an oil. |
Well, most launderers use other products for grease stains, so may not lift too well. Talking about textiles here though.
Tarmac is covered with a protective layer though, and if where I think she has spilled it, is fairly new, so the diesel may not have been able to get through the surface.
