Most boat owners have to keep their vessels at home and as is such, there can be messes made due to the general maintenance that happens there. One such mess can be spilling boat motor oil everywhere. Cleaning up oil can be a pain; here are some tips that will help and make it slightly easier:
• Pour cola on the oily or dry stained areas, and leave the cola on overnight. Squirt a generous amount of dishwashing liquid into a bucket until you have a good lather. Rinse with the soapy water, then with a garden hose.
• Sprinkle baking soda or an absorbent powder such as cornmeal or sawdust on the oily spots. If the stain is dry, wet it first to make a scouring paste. Scrub with a stiff brush or push broom.
• Sprinkle automatic dishwasher detergent on the oily concrete. Leave it for several minutes, then pour boiling water on the stained area. Scrub with a stiff brush or push broom, then rinse.
• Try a commercial concrete cleaner such as Garage and Driveway Cleaner by Red Devil Co. or a grease solvent such as Benzine. Follow the manufacturer’s instructions.
• Sprinkle trisodium phosphate (TSP) on the oily concrete. If the stain is dry, wet it first. Let it stand for 30 minutes. Scrub using a stiff broom. TSP is a dangerous product; if you must use it, wear rubber or latex gloves, safety goggles and protective clothing. Also, never wash a TSP product down storm drains.
• As a last resort, combat tough spills with muriatic acid and a pressure washer. Apply the acid following the manufacturer’s directions, and let it soak for several seconds. Follow with a pressure washer set at 2,500 to 3,000 lbs. per square inch (psi), or 176 to 211 kg per square cm. Like TSP, muriatic acid is a dangerous product; likewise, if you must use it, wear rubber or latex gloves, safety goggles and protective clothing, and never wash such a product down storm drains.
• After trying any of the strategies above, sprinkle baking soda over the cleaned area to neutralize the solution you’ve used.
