How to Clean Your Concrete Patio So It Looks Brand New

There’s nothing like sipping lemonade or flipping burgers on your backyard patio in the warmer months. But after a long season of weather and foot traffic, that concrete surface might be looking a little worse for wear. Concrete is durable, yes, but it’s also a porous material that absorbs spills and stains. This makes learning how to properly clean a concrete patio all the more vital.

With the right tools and techniques, you can safely and effectively remove built-up dirt and make your patio look brand new again. We asked seasoned handymen for their best tips to cut through the mess without damaging your patio's surface or nearby landscaping. Here's how to refresh your concrete patio and make the most of your outdoor space.

How to Clean a Concrete Patio

Whether you're hosting a backyard brunch or just soaking up a sunny afternoon solo, a well-kept patio sets the scene. But even the most stylish setup can be dulled by dingy concrete. If your patio has lost its sparkle, don’t worry: Follow the steps below to restore it to its former glory.

Materials Needed:

• Broom or leaf blower
• Garden hose with spray nozzle
• Bucket
• Stiff-bristled, long-handled scrub brush 
• Dish soap or degreasing cleaner
• White vinegar or baking soda
• Protective gloves
• Pressure washer (optional)

Instructions:

1. Sweep Thoroughly: "It’s like mopping the house," says repairs and renovations expert Paul D. "You always sweep first." Use a stiff broom or leaf blower to remove leaves, dirt, and dust. This clears the way and helps prevent making muddy messes when you add water.
2. Mix a Mild Cleaning Solution: In a bucket, combine warm water with a few squirts of dish soap or a degreasing cleaner. If your patio has mildew or algae, add one part white vinegar to two parts water for extra cleaning power that’s safe for most plants and surfaces. “Dish soap and cleaning vinegar are the only things you need for a routine patio cleaning,” says Scott C., co-owner of the handyman service company, The Punchlist Boys. “Specially formulated cleaners can be useful for really tough stains or for preparing a surface to be sealed—but for a regular seasonal cleaning, stick to the basics.”
3. Scrub the Surface in Sections: Using your long-handled scrub brush, work in small sections, applying the soapy solution and scrubbing in circular motions. Pay extra attention to areas with visible stains or discoloration. "Don’t try to 'hands-and-knees' a patio," warns Paul. "Trust me. Your knees will never forgive you. Get a long-handled brush mop with stiff bristles and use it to clean the entire space."
4. Rinse Thoroughly With a Hose: Once you’ve scrubbed a section, rinse it well with the garden hose. Be sure to spray from the back of the patio toward the edge to push dirty water off the surface rather than spreading it around. "Use a hose nozzle that creates a pressurized stream to remove all the soap and loosened dirt," Paul adds.
5. Spot Treat Stubborn Stains: For rust or grease stains, try sprinkling baking soda directly on the spot, then scrubbing with a vinegar and water solution. Let it fizz for a few minutes before rinsing. For really tough grime, you can repeat the process or use a concrete-safe degreaser.

For an Extra Deep Clean:

If your patio hasn’t been cleaned in a while (or you're after a like-new finish), a pressure washer can be a helpful tool. “We always use the pressure washer on a low setting with a fan tip, and keep the nozzle at least a foot away from the surface to avoid etching the concrete,” explains Paul.

A job best reserved for a stretch of sunny days, after pressure washing and allowing your patio to dry, consider applying a concrete sealer to protect against future stains and weathering. And make regular sweeping and spot-cleaning part of your outdoor maintenance routine to keep your space looking its best all season long.
