With all due respect to the previous answers, I'm a little confused as to whether or not the most appropriate product is available in your country as it has not been mentioned. The most effective way of removing oil stains from a driveway is with the product intended for removing oil and grease: Degreaser. Auto-parts stores usually sell it in spray can ...

While wastewater goes through elaborate processing to remove contaminants, if a thing can be disposed of by other means, it is better to do so rather than adding it as ...
