Pavers are a popular choice for patio areas and walkways in yards everywhere. These precast stone blocks can be laid out in many different patterns, and are available in a variety of shapes and sizes, making them a versatile outdoor choice. Unfortunately, trees can stain most types of pavers easily, making them look old and dirty very quickly. One of the worst trees for staining pavers is oak trees. Luckily, removing these stains is not as difficult as you may think.
Sprinkle a few drops of apple cider vinegar on the stain. Vinegar is a natural cleaner which, through its acidity, can break up stains without damaging or etching the paver in any way.
Add 1 to 2 teaspoons of baking soda to the vinegar until you have a fizzy thick paste. The natural chemical reaction between the baking soda and vinegar creates this useful, but harmless, fizzing. Baking soda is a gentle, natural abrasive cleanser that will help remove the stain from the pores of the paver, continuing the action begun by the vinegar.
Scrub the paste into the stain with a good scrub brush. To completely remove the stain, spend at least 5 minutes scrubbing. Depending on how long the stain has been there, you may need to apply more vinegar and scrub longer.
Rinse the paver off with a water hose and allow it to dry in the sun. Vinegar and baking soda rinse away clean and won't leave residue or a film on the stone.
Purchase a product specifically to clean concrete and stone for the few occasions a stain is too deeply set-in to be removed with baking soda and vinegar. Make sure the cleanser is made to clean these materials without causing etching or damage due to high acidity. Go to a trusted home store and discuss with the sales associate exactly what material your pavers are made of; that will dictate what cleaners are safe, and which aren't.
Sweeping regularly and keeping the pavers clean of leaves and debris will cut down on how often you need to scrub stains away. If you clean a stain as soon as you notice it, the stain will not set in as deeply, and will require a great deal less work to remove.
