How To Clean Flagstones With Flagstone Cleaner
Mix The Flagstone Cleaner
Before you jump into mixing the flagstone cleaner, you should protect yourself with rubber gloves and safety glasses .
You can now safely mix the flagstone cleaner with water, following the instructions printed on the back of the packaging. The mixing ratio varies from brand to brand.The StoneTech Stone & Tile Cleaner calls for 2 oz of cleaner per 1 gallon of warm water for light jobs and 4 oz per 1 gallon of water for heavy jobs.
Apply Flagstone Cleaner
Apply the diluted flagstone cleaner to the surface using a stiff scrubbing broom or brush. But don’t scrub the flagstone just yet! Simply spread the cleaner all over the stone and mortar. Put a little extra cleaner on the stained areas.
Let The Cleaner Sit
Let the solution sit for 2-3 minutes, or as instructed on the packaging. Give the flagstone cleaner time to break down the stains and kill the mildew.
You can now scrub the flagstone with your stiff scrubbing brush. Work in sections, so you don’t miss any areas or corners.
Don’t be afraid to apply more cleaner to particularly dirty areas. Continue scrubbing until you are satisfied with the results.
Rinse The Flagstone Patio
Rinse the cleaning solution off the flagstones using a garden hose. Push the excess water off the patio with your broom or a squeegee mop to expose any remaining spots. Apply the cleaner to the leftover stains and scrub them away. Rinse them off afterward.

How To Clean Flagstones With Vinegar
Treat The Problem Areas First
Assess the state of your flagstone patio and determine which areas need heavier treatment. Spray undiluted white vinegar directly on the stained or molded patch and scrub it a little with a hard-bristle brush.
Leave the vinegar to soak for 30 minutes. When the timer goes off, take your hard-bristle brush and scrub the area thoroughly.
Wash off the treated area with plenty of water. If you are satisfied with the results, you can move on to the next step.
Spray Diluted Vinegar On The Whole Surface
Dilute white vinegar with an equal amount of warm water. I don’t recommend using any other type of vinegar for this project because it might stain your beautiful flagstone.
Spray the vinegar solution all over the flagstone patio using a garden pump sprayer, like this one . You can also use a mop or a sponge to spread the diluted vinegar onto the surface. Just remember to use rubber gloves when doing so.
Rinse With Water
Leave the vinegar solution to sit for at least 30 minutes before rinsing it off with your garden hose.
Try Cleaning Your Flagstones With Bleach

How To Clean Flagstones With Bleach
Dilute The Bleach
First and foremost, protect yourself with rubber gloves and safety glasses. Wear old clothes that you won’t care about if they get stained with bleach.
You can use straight outdoor bleach, like this one made by Clorox , or any other Sodium Hypochlorite based product, like the popular 30 SECONDS Outdoor Cleaner . This product may not be marketed as bleach, but water solutions of Sodium Hypochlorite are commonly known as bleach.
Dilute your outdoor bleach with water in the ratio suggested on the back of the container. For instance, the 30 SECONDS Outdoor Cleaner needs to be mixed with equal parts of water to achieve the 50/50 dilution. See picture above for reference.
Do A Patch Test First
Bleach is a potent substance that can damage and discolor your flagstones if not used correctly. You can see bleach damage on the limestone in the picture above. That is why I recommend you do a small patch test somewhere in the corner of your patio just to be sure.
Treat The Stained Flagstone
Get your stunning Allen Roth patio furniture out of the way, so it doesn’t get damaged by the bleach.
You can now spray your diluted bleach on the flagstones. Focus on areas that are affected by stains, mold, and algae. The next step you take depends on the product you are using.
Some outdoor bleach products, including the No products found, call for scrubbing, while others leave it as an optional step.
Let the Bleach Sit Before Rinsing
Check the label for how long you should let the bleach sit on the flagstone to get the maximum results. The duration time varies depending on the surface you are cleaning.
The 30 SECONDS Outdoor Cleaner needs to sit for 15 minutes on stone patios and only five minutes on wooden decks.
When the timer goes off, rinse the flagstones with plenty of water to remove the bleach completely.
