Relaxing on your apartment balcony is a great way to enjoy the fresh air, but even concrete still gets a little dirty out in the elements. Luckily, there are a ton of things you can use to clean your balcony without a hose. We've put together a list with some easy cleaning tips and recommendations on what to use for stubborn stains so you can go outside and enjoy your space!

Sweep loose dust and debris.

  1. Use a stiff-bristled broom for the best results. Start near the edges of your balcony and work towards the center, collecting the dirt in a couple of spots. Be sure to reach all the tight corners of your balcony since that’s where dirt builds up the most. Once you’ve swept up as much as you can, collect it all in a dustpan and throw it away.[2]
    • Always use smaller and shorter strokes. Not only will these be more precise, but they also won’t make a mess in the process of sweeping.
    • If possible, make small dirt piles, as you don’t want to try and move dirt too far around the room. Having many small piles will typically be more effective than trying to create one big pile.
    • If something is really stuck to the concrete, try loosening it with a plastic scraper.
    • If you have trouble reaching tight spaces with your broom, try using a vacuum with a hose attachment.

Sponge or mop your balcony.

  1. The water helps break apart stubborn dirt your broom couldn’t reach. Fill a bucket with warm water and mix in a little bit of mopping solution or detergent. Use your sponge to wipe down the walls or railings around your balcony. Then, mop the floor with your cleaning solution working from the edges of your balcony toward the center.[3]
    • You can use your sponge on the balcony floor if you don’t have a mop.
    • For more scrubbing power, use a stiff-bristled brush to scrub off the dirt.
    • Always be mindful of anyone who has a balcony directly underneath yours since water running off could drip down and get their balcony dirty. Always wring out your mop or sponge before you start so there isn’t as much excess water.

Try dish detergent for leaf stains.

  1. Scrub the detergent onto the stains with a stiff-bristle brush. If you have brown stains from old leaves, combine about 12 cup (120 ml) of liquid dish soap into a bucket with 3 gallons (11 L) of water. Pour the solution on top of the stains and work it into the concrete until the stains break apart. Rinse the solution off with clean water to finish up.[5]
    • For a little extra cleaning power, try sprinkling powdered laundry detergent on the stain after rinsing it off and scrubbing it with your brush again. Detergent that says it’s effective against food stains works the best.

Use trisodium phosphate for oil stains.

Spread diluted bleach for mold and mildew.

  1. Bleach kills mold on contact and prevents it from coming back. Put on a pair of gloves, mask, and safety glasses to protect yourself from the bleach. Add equal parts of bleach and water into a spray bottle or bucket. Spread the solution over the stain and let it sit for 10 minutes. After that, use a stiff-bristled brush to lift up the stains.[9]
    • Since bleach could discolor your concrete, spot-test it in an inconspicuous area of your balcony before using it on the stains.
    • Only use as much bleach solution as you need since the runoff could kill plants or flowers.
10

Use a pressure washer for the deepest clean.

  1. Pressure washers break apart stubborn debris, but require a hose. You can rent a pressure washer from a hardware store or buy your own. Connect the pressure washer to a hose and set the machine to around 3,500 PSI. Hold the washer hose about 8 inches (20 cm) off the ground and turn on the pressure washer. Work in back and forth strokes across the concrete to remove deep-set stains and debris.[11]
    • Pressure washers aren’t the best choice if someone has a balcony underneath yours since the water will leak and spill down onto it. If you do plan on cleaning your balcony, let anyone who lives directly below you know so they can move their items.

Warnings

  • Always wear gloves and safety glasses when using strong chemical cleaners like bleach and muriatic acid.[14]

  • Vinegar can actually wear away concrete and make it weaker, so try another cleaning solution instead.[15]

  • When sweeping, trying to go too quickly with big strokes will end pushing dust and debris around the balcony.
