Who has not noticed the nasty spots of oil on the garage floor or driveway? They are unsightly, present a health risk to your family and pets, can damage the concrete surface and lower the value of your property.
A leaky car, a motorbike or a lawnmower can damage your garage floor.
It is pretty hard to completely remove a stain, because oil penetrates deep into the concrete. But fortunately, there are several ways to limit the damage.
Use kitty litter (or sawdust)
-Spreading a layer of kitty litter (sawdust) over the affected area will extract the excess of oil from the concrete.
-For better results let the kitty litter to stay one or two days.
-After two days, sweep and throw away the dirty litter.
-Now, spread a layer of dried cement over the spot.
-Allow again two days for cement to pull out more oil.
-Sweep away the dirty cement.
-Make a paste of laundry detergent and water.
-Cover the stain with this paste.
-Using a wire brush scrub thoroughly the stain.
-If it is necessary, add more detergent paste and water.
-Rinse well with a lot of water.
Use Sodium Hydroxide and Detergent
Another way would be to use Sodium Hydroxide and detergent. You can buy Sodium Hydroxide from any hardware store.
It is a more expensive way but it can give good results.
Use fuel such gasoline, diesel or kerosene
Remember these products are flammable, so be extremely careful when you use them.
-Gasoline will act as a solvent, which will dilute the oil.
-Cover the stain with a plastic sheet. This will stop gasoline to evaporate.
-It is prudent to have beside you a garden house.
-Scrub and rinse well with a lot of water.
The disadvantage of this method is that gasoline ruins the concrete surface “eating” the concrete.
