When you have stains on your concrete driveway, it’s typically best to treat them with the appropriate products before you apply the sealer. For best results, work on stains while they’re fresh. Always follow the cleaner directions, and wear the specified safety gear, especially eye protection. Start by determining what kind of stains you have to find the best concrete cleaner for the job.
Remove Oil and Grease Stains on Concrete
Select the appropriate pressure washer spray tip or nozzle based on how deep your stains are. The wide-pattern spray tips are lower pressure and the narrow-pattern tips are for tough stains but are capable of marking concrete. Many models come with a specific nozzle for spraying cleaners. If your pressure washer kit doesn’t include spray tips or nozzles, you can purchase universal ones.
Wear the appropriate safety gear and clothing: splash-resistant safety goggles, a long-sleeved shirt, long pants, closed-toe shoes and chemical-resistant gloves.
