We had oil stains from a broken car on the concrete pavement. It worked. A small white veil has remained on the pavement stick after use, maybe we would have the dry powder rather than just turn away to scrub away with a stiff brush. But with the bright rest on the pavement can be more likely to live than with the oil stains. We are confident that these white-balance covering even disappear over time. The product is very economical in use - the next oil spill occurs guarantees used again.
