How to Clean Concrete Patio Without Killing Grass in 5 Proven Ways

Cleaning your concrete patio is a great way to make it look new again. However, some people worry that the pressure washer they are using will harm their grass or other plants in the area. Luckily this blog post will show you how to clean concrete patio without killing grass.

A concrete patio is a beautiful way to provide more outdoor space for your family, but the problem is that it can be challenging to keep clean. Dirt, grass clipping, and other debris can get stuck to it making your patio look dirty.

And if you attempt to clean it with certain household cleaners, it can actually do more harm than good. You may end up damaging the grass around the patio.

The good thing, though, is there are simple ways of how to clean concrete patio without killing grass. Here are some tips on how you can give your concrete patio a good scrubbing without damaging the lawn.

How to Clean Concrete Patio Without Killing Grass

The majority of homeowners with a concrete patio end up killing their grass because they are unaware that using chemicals to clean their concrete can kill their grass.

Let’s have a look at several things you can do to help with this problem.

1. Use Vinegar to Clean your Concrete Patio

Vinegar is a great cleaning tool. If you have a standard concrete patio, then try adding 1/2 cup of vinegar to 3 gallons of water and use it as your cleaner. The acidity from the vinegar will help break down the dirt particles leaving your patio looking good as new!

The trick here is to scrub with a stiff-bristled brush and let it dry completely before walking on the surface. If you’re not comfortable using a large amount of vinegar, use white distilled vinegar instead.

It still has that acid that can kill those stubborn dirt particles, but it won’t kill your grass or give anything around the lawn an unpleasant smell.

2. Use Baking Soda & Water

Baking soda is another great household cleaner that is safe for both humans and animals but can be very effective at killing dirt particles on the surface of your concrete patio. Just spread some baking soda over the surface you wish to clean, then use a brush to scrub down.

After scrubbing it, use a hose with plenty of force behind it and rinse it away. It will leave your patio looking new! However, if you have very stubborn stains, you may have to scrub more than once.

3. Use Diluted Bleach to Clean your Concrete Patio

Using bleach to clean your concrete patio is another way to get it looking clean again. However, you should use caution when using bleach because it can be harmful if used in excess or applied incorrectly.

You’ll need about one gallon of water and half a cup of liquid chlorine (or bleach). Stir the liquid well, then add some liquid dish soap (about 1 tbsp) which helps the cleaning process. You can also add up to 3 gallons of water if needed to make sure that all the surface is covered with this mixture.

Let it sit for 10-15 minutes before scrubbing with a stiff brush. It should start removing tough stains very quickly! Just make sure that you rinse everything off once you’re done scrubbing!

4. Using Trisodium Phosphate

Trisodium phosphate is another good cleaner for your concrete patio. It works by breaking down the oils so that you can easily wash them away.  This is a great product to use if you have pets and notice their urine stains on your concrete.

Simply mix it with water until you get a smooth consistency, then scrub with a stiff brush. You should see the stains start to fade away as the cleaner works its way into the porous surface of your concrete.

When cleaning, just remember that you can always add more water to dilute the solution! Be sure to wear gloves and ensure that no children or pets are in the area when using this type of cleaner. If the soil around your patio has grease stains, then you’re in luck because this mixture will remove them!

    Hi, I’m Ricky. I’ve been involved in lawn care and landscaping from when I was 15. To be honest, I didn’t like the idea of pushing mowers, collecting grass clippings, and maintaining flowerbeds at the time. But having seem the passion my parents had for gardening and outdoors and the effort they put in maintaining the health and beauty of our landscape, I couldn’t help but not only admire their hard work but also I became a part of it. As someone who loves to spend time with nature’s best, I find myself learning a lot more about gardening and outdoors on a daily basis. Not to mention I love to share the knowledge I’ve gathered over the years with my readers at We Mow Dallas. To be clear, I don’t have a Master’s degree in gardening or anything like that. Everything I’ve learned about gardening, landscaping, and lawn care spring from passion and engagement with my parents. And with a ton of free information out there, plus the ability to run tests and determine what works best for lawn care and landscaping, every day is an opportunity to learn and implement something new. My goal with We Mow Dallas is to teach you exactly how to maintain your lawn and landscape. And since I walk the talk in reality, you shouldn’t hesitate to join me in this wonderful world of landscaping and lawn care. K Beatrice
