I can easily remove kerosene stains from concrete floors by wiping that with help of any floor cleaner which has the capacity to remove stain.I can clean that when i pour slight hot water over the stain,then use any cotten cloth to wipe it.
For removing kerosene stains from concrete floor, you will have to apply wood saw powder mixed with lime powder first. Leave it for 2-3 hours, then wipe off with clean cloth. Again put diluted sulphuric acid, wipe off after 10 minutes. No more stain !
Kerosene stains are very very difficult to remove, and it is best to remove them very carefully. I suggest using gasoline and baking soda, or, failing that, tons and tons of bleach.
acids and floor cleaning liquids can be used.some mild soaps also can be used.apply the liquid or soap for a small time on the stain,leave for a while, then ru b them with a wet cloth, so that the stain goes away .
