Flagstone is a common choice when constructing walkways, patios and even some indoor areas. The flagstone provides a rustic, natural look that is heavily durable to wear and tear. To keep the flagstone looking its best, clean with a solution that is safe for the flagstone and effective in keeping the stone clean and free of build-up. Vinegar works well in this situation, when diluted properly, as it disinfects plus deodorises without use of harsh chemicals.
Fill a bucket with about 1 gallon water and 3 tbsp white vinegar.
Rinse outdoor flagstone with the garden hose to remove loose build-up.
Dip a broom or nylon scrub brush into the vinegar water and brush across the flagstone. A broom works well on large outdoor areas of flagstone.
Rinse outdoor flagstone with the hose when finished and allow to air dry, or wipe over the flagstone with a damp mop to collect the cleaning solution and lifted residue.
