The Best Way to Remove Leaf Stains From Concrete Driveways

When autumn leaves fall to the ground, you may find brown stains on your concrete driveway. These stains are caused by tannin transferring from the leaves to the porous concrete surface. Despite the strength and durability of concrete, it is susceptible to organic stains. Fortunately, removing leaf stains isn't difficult. The best way for you to remove leaf stains is to ensure you remove tannin stains from the concrete surface as well as those that have been absorbed.
