Understanding Your Concrete Surface

Before learning more about the cleaning process, it's important to understand the type of concrete surface you are dealing with. Concrete can be sealed, unsealed, polished, or painted, and each type requires different cleaning methods.

Precautions To Take When Cleaning Concrete

Clear & Prepare the Area You Want to Pressure Wash

The first step is to clear and prepare the area you want to wash. Remove any plants, furniture, or other items from the area for outdoor concrete surfaces. If you want to clean indoor areas like basement floors, cover nearby items with plastic sheeting and tape to protect them from mold spores and cleaning solutions.

Unsealed Concrete

This particular kind of concrete has tiny pores that allow it to soak up stains, making it tougher to clean.

Sealed Concrete

Sealed concrete is an excellent choice due to the protective layer it forms, which enhances its resistance to stains and simplifies the cleaning process.

Polished Concrete Floors

This type of concrete is treated to be smooth and shiny and is often found indoors in commercial or residential spaces.

Precautions When Cleaning Concrete

Remember to take certain precautions when cleaning concrete surfaces. It's best to hire professional pressure washers who are equipped with the latest tools and know the proper techniques for cleaning different surfaces, including concrete."

Test Cleaning Solution on a Small Area

Always test your cleaning solution on a small area of the concrete surface. This will confirm that the solution does not cause discoloration or damage.

Use Appropriate Cleaning Solution

Mild soap and water are sufficient for general cleaning. However, specific cleaning solutions are necessary for tougher stains. Be sure to purchase the right cleaning solution from a reputable brand with good reviews. If you are unsure, you can check online to find out which cleaning solution is best for concrete cleaning, or you can hire a professional pressure washing company for this job, as they will come equipped with the best cleaning solutions.

Oil Stains: A mixture of water and powdered laundry detergent is highly effective. Apply the paste to the stain and let it sit for a few minutes, then scrub and rinse.

Grease Stains: Use a mixture of degreaser, baking soda, and water.

Avoid Harsh Chemicals

Please remember to use caution when cleaning concrete surfaces. Strong bleaches or acids can cause damage, especially if the concrete is unsealed or painted. You can also choose gentler cleaning agents to ensure the longevity and appearance of the concrete inside or outside your property.

Proper Ventilation

When cleaning indoor concrete floors, make sure that the area is well-ventilated to avoid inhaling cleaning solutions’ fumes.

Concrete Cleaning Right Tools

Use the Right Tools

A pressure washer can be very effective for outdoor concrete surfaces like patios and driveways. However, use it carefully to avoid damaging the concrete. A garden hose with a spray nozzle can suffice for lighter cleaning tasks. You should use nylon brushes to scrub concrete. Avoid metal brushes, as they can scratch and damage the concrete surface.

Protect Yourself

Always wear protective masks, gloves, and goggles when handling cleaning solutions and scrubbing concrete surfaces.

Rinse Thoroughly

After cleaning, rinse the concrete surface thoroughly to remove any remaining cleaning solution. Rinsing prevents residue buildup, which can attract dirt and cause discoloration.

Steps for Cleaning Different Types of Concrete Surfaces

Cleaning Outdoor Concrete (Driveways, Patios)

Clean outdoor concrete surfaces by removing loose debris and dirt with a broom. Now apply a cleaning solution for the type of stain you're dealing with (e.g., powdered laundry detergent for oil stains).

After this, a pressure washer is used to rinse the surface thoroughly. Start with a low-pressure setting to avoid damaging the concrete. If you are cleaning stubborn stains, reapply the cleaning solution and scrub it with a brush before rinsing it again.

Cleaning Indoor Concrete Floors

Start with sweeping or vacuuming the concrete-made floor to remove loose dirt. For polished concrete floors, you should use a pH-neutral cleaner to avoid damaging the finish. If you are cleaning painted concrete floors, avoid abrasive cleaners and scrubbing tools to prevent paint scratching. Mop the concrete floor with the cleaning solution and rinse with clean water. Now dry the floor with a clean and dry towel or mop to prevent water spots.

Cleaning Sealed Concrete

Because of their protective layer, sealed concrete surfaces are more convenient to maintain and clean. For routine cleaning, it's best to use a mild soap solution. If there are more stubborn stains, you should use a specialized concrete cleaner that is safe for use on sealed surfaces. To preserve the sealant, avoid using abrasive tools that can scratch or damage it.

Regular Maintenance Tips For Concrete Surfaces

Remember to clean your concrete floors by sweeping and mopping them regularly to avoid dirt buildup. Applying a special concrete sealer, you can also protect the concrete floors from stains and make them easier to clean. If you spill something, make sure to clean it up right away to prevent stains. On top of that, be careful not to drag heavy things across the floor to avoid damage and scratches. Check your concrete floors for any damages or cracks, and if you find any, take care of them quickly to stop them from getting worse.


When considering what precautions you should take when cleaning concrete, it's essential to recognize the unique challenges presented by a concrete patio. To remove stains effectively, especially tough stains such as rust stains or grease and oil stains, using the right washing methods and techniques is crucial to clean concrete thoroughly without causing damage. Always hire a professional pressure washing company to clean concrete surfaces inside or outside your property. They know the best cleaning techniques and follow proper safety measures.
