A concrete patio is a lovely way to give your family more outdoor space, but the drawback is that it’s challenging to keep clean. Your deck may look dirty because of dirt, grass clippings and other debris sticking to it.
The time of year can also impact you; after a long winter, you can find your patio has a grubby appearance. You can clean your concrete patio or even a concrete driveway and make it look fresh, yet there are things to be cautious of first.

How Do You Clean Tough Stains From Your Concrete Patio?
You can purchase several efficient concrete cleansers, but many contain solid acids and harsh chemicals that harm or kill nearby grass.
Instead, clean the dirt, moss, or mildew from your patio or concrete pathway using the right tools and safe cleansers.
- Sweep the walkway with a stiff-bristled broom to remove any dirt or debris.
- Mix two tablespoons of mild dish soap and 3 gallons of warm water in a large plastic bucket.
- Spay your patio with a garden hose.
- Dip your stiff-bristled broom into your bucket.
- Scrub the entire surface of your pathway or patio. You may need some elbow grease to remove even tough stains.
- Rinse your pathway using your hose. Ensure you spray the concrete and not the grass.
- Let your patio pathway dry completely before checking you have removed all the stains.
You can also spray the area using a power washer on low, although keep the pressure washer spray away from nearby plants and grass as you could damage them.
Cleaning Concrete Patio Without Killing Grass
What You’ll Need:
- Plastic Bucket
- Hose
- Stiff Bristled Broom
- Dishwashing Liquid
- Hot Water
Directions
- First, rinse off the patio to remove residual dirt, dust, and other debris.
- Next, wash the concrete with no bleach, soap, or water.

- The best way is to work on a small area at a time, focusing on dirty regions so they aren’t left while cleaning the rest of the space, which should already be clean.
- After applying your DIY concrete patio cleaner, all discolorations should come off quickly and dry with a slight sheen.
- Avoid letting soap dry before rinsing again.
- After the patio has dried, sweep it to remove dirt and dust.
- Boiling water over the concrete surface will break down grease but leave an oily residue that may kill plants if gone too long.
- Pour dish soap and warm water on the dry floor to create suds.
- Use a scrub brush to remove dirt, then rinse.
- Never leave bleach or strong chemicals on the freshly washed patio; they can damage the grass and contaminate nearby groundwater.

How To Get Rid Of Moss, Mold, and Grease on Concrete Patio
Because concrete is commonly used for driveways, patios, and pathways, most cleaning solutions are geared toward oil spills, although other issues are from moss, mold, and grease.
Here are a few tips to manage the problem:
- Grease, mold, and moss can all be removed using a vinegar solution.
- Use white vinegar cleaning solution diluted in equal water to remove moss and mold.
- Grease responds similarly to the same solution, and ensure you add enough water to saturate the patio to prevent the vinegar from absorbing into your concrete.
- Avoid the grass, use a spray bottle with a smaller spread, start in the center, and work your way outward. A water-resistant sheet can cover your patio’s surroundings.

Environmentally Friendly Cleaning
- Once a stain occurs, more forceful cleaning methods are required.
- Start gently using water, degreasing detergent, and a broom with stiff bristles.
- Water the plants and soil nearby, which prevents chemicals from leeching into the ground too much.
- Saturate the concrete with water, then use a detergent and water solution while scrubbing with a broom.

Although using a pressure washer to clean concrete might seem quick, these machines use 1,500 to 3,300 pounds per square inch of pressure.
If the nozzle is too close to the concrete, the high-pressure stream will etch the surface, hurting people.
If you pressure wash along the edge, the water’s force will probably rip out soil and grass. The plant may never fully recover from the damage, even though the grass can be replaced. (Learn How Long To Run Soaker Hose For Tomatoes)
