Concrete, Cement - Grease
Stains
In a garage, it is advisable
to place a shallow metal pan under the car to catch dripping
oil. Spreading the area under the car with sand or sawdust will
help absorb dripping oil. Periodically saturated sand or sawdust
should be scraped away and fresh, clean material put in place.
This will prevent tracking oil to other areas of cement or into
the house.
If oil or grease is spilled
on porch or patio cement, apply an absorbent powder such as fuller's
earth, cornmeal, or sawdust to absorb as much oil as possible
immediately. Leave it on stain for a few hours and sweep up.
To remove the grease stain:
1. Using a stiff long handled brush, scrub stain
with concentrated detergent suds. Rinse well with hose. Dry and
repeat if necessary.
2. Sprinkle "dishwasher" detergent (dry)
on wet concrete. Let it stand a few minutes; pour boiling water
on area. Scrub and rinse. Use rubber gloves on hands.
3. Commercial Product: One brand is Garage and Driveway
Cleaner by Red Devil Co. available in paint or/and hardware stores.
It can also be used on blacktop surfaces. Other similar brands
may be available in your area.
4. On wet oily surface of concrete, sprinkle with
trisodium phosphate. Allow to stand 15 to 30 minutes, then scrub
with stiff brush and hot water. Rinse with clean water. Do not
use on asphalt.
OR: Dissolve a cup trisodium
of phosphate in 1 gallon of hot water. Pour over stained cement
surface generously and allow to soak 15 to 20 minutes. Scrub
vigorously with stiff brush or broom. Rinse off with hose. Repeat
if necessary. Do not use on asphalt.
5. Scrub the concrete with a grease solvent to remove
as much as possible of the grease stain. Have good ventilation
and avoid spark or flame as solvents are flammable. Benzine,
often recommended, can ignite, just from a spark from friction
or rubbing.
6. Mix 1 part sodium citrate to 6 parts water and
6 parts glycerine and add enough whiting or fuller's earth to
make a thick paste. Spread paste on oil or grease stain. Let
stand 1 week. Add new paste when it dries. Flush with water after
brushing dry paste away. Repeat if necessary. |
