Cleaning a driveway can be a daunting task, but with the right tools and knowledge it can be done quickly and effectively. In this article, we will discuss the process of cleaning a driveway, from start to finish, as well as the importance of following the Clean Water Act and safety precautions.
Before beginning the cleaning process, it is important to be aware of your local runoff laws. According to the Clean Water Act, chemicals should not be allowed to leave the property.
To avoid any violations, it is important to look into reclaimed systems that capture runoff and put it back into a tank on the property. When pre-treating the driveway, it is important to start with the low spots first. This will help to avoid a massive puddle that would be difficult to fight. It is also important to wear the proper Personal Protective Equipment (PPE) when pre-treating. This includes a respirator and waterproof footwear.

Once the pre-treatment is complete, it is time to fire up the pressure washer. It is important to use a pressure washer that is at least four gallons per minute. This will help to ensure that the surface cleaner is able to do its job effectively.
When using the surface cleaner, it is important to move slowly and evenly across the driveway. This will help to avoid any lines or gouges in the concrete. It is also important to rinse the driveway as you go, as this will help to avoid any dirt settling back into the pores of the concrete.
Post-TreatmentOnce the driveway is clean, it is important to post-treat the area. This will help to feather out any lines left from the surface cleaner and make the driveway look more professional. It is also important to check for any rust stains and treat them with a separate chemical, such as Rust Rescue rust remover.
Post Treat at the same ratios as pre-treat above.
