Cola contains phosphoric acid which has some effect, but it's not as effective as proper degreasers.

Apply degreaser repeatedly. For very old stains, use a TSP (trisodium phosphate) and water mixture.

Stain Removal

Stain removal is all about speed and technique. Here's the proven method for tackling oil stains on driveway effectively.

1
Absorb fresh oil
If the oil is fresh, cover with cat litter or sawdust and let sit for several hours to absorb the oil. Sweep up.
2
Apply degreaser
Spray or pour Turbo Clean Degreaser directly on the stain. Let it sit for 15-30 minutes.
3
Scrub with a stiff brush
Use a stiff push broom or bristle brush to scrub the stain vigorously. Add more degreaser as needed.
4
Apply dish soap for residue
After scrubbing with degreaser, apply dish soap and scrub again to break down any remaining oils.
5
Rinse with the hose
Rinse thoroughly with high pressure water from the garden hose. Repeat the process for stubborn stains.
