1. Stop the source leak. If it is originating from a leaking bucket, sloppy pours into a grease container, or some other source, stop the underlying source of the grease or oil first before beginning to tidy up.
2. If the spill is fresh, the oil will keep spreading so the most effective thing to carry out is create a makeshift berm to stop it from spreading. You can use a garden hose to lay around the perimeter of the spill to stop it from spreading.Do not attempt to hose down the spill … it will only spread!
3. Absorb the grease with some type of dry bulking agent. Kitty litter or saw dust is ideal. If you don’t have that try flower, mulch, or straw.
4. After greasy material has been soaked up, apply a degreaser and work into porous surface with a thick bristled brush. Hose down, mop, or powerwash.
