When it comes to maintaining the beauty and durability of sealed concrete, using the right cleaner is essential. With so many products on the market, it can be overwhelming to decide which one to choose. In this article, we’ll delve into the world of concrete cleaners, exploring the different types, their ingredients, and what to look for when selecting a cleaner for your sealed concrete.
The Importance of Cleaning Sealed Concrete
Sealed concrete, while more resistant to stains and damage than unsealed concrete, still requires regular cleaning to maintain its appearance and extend its lifespan.

What to Look for in a Cleaner for Sealed Concrete
When selecting a cleaner for your sealed concrete, there are several factors to consider.
pH Level
A cleaner with a pH level close to neutral (pH 7) is ideal for sealed concrete. Avoid using cleaners with high or low pH levels, as they can damage the sealant or concrete.
Ingredients
Choose a cleaner with gentle, non-toxic ingredients that won’t damage the sealant or concrete. Avoid cleaners containing harsh chemicals, abrasive materials, or volatile organic compounds (VOCs).
Concentration
Select a cleaner with the appropriate concentration for your needs. A concentrated cleaner may be more cost-effective, but may also require more water to dilute, increasing the risk of residue buildup.
Certifications and Compliance
Look for cleaners that meet industry standards and certifications, such as the U.S. EPA’s Safer Choice program or the International Sanitary Supply Association (ISSA) Cleaning Industry Research Institute (CIRI) certification. These certifications ensure the product meets certain environmental and safety standards.
How to Clean Sealed Concrete
Once you’ve selected a cleaner, it’s essential to follow the manufacturer’s instructions and take necessary safety precautions.
Preparation
Before cleaning, remove any loose debris or dirt from the surface using a broom or blower. Sweep or blow the area to remove any dust or particles that may interfere with the cleaning process.
Application
Dilute the cleaner according to the manufacturer’s instructions and apply it to the sealed concrete surface using a mop, soft-bristled brush, or spray bottle. Avoid using high-pressure washes or harsh scrubbers, as they can damage the sealant or concrete.
Rinsing
Thoroughly rinse the area with clean water to remove any remaining cleaner and debris. Use a clean water rinse to prevent re-depositing dirt and grime onto the surface.
Drying
Use a clean, dry cloth or towel to dry the area, or allow it to air dry. This helps prevent water spots from forming and reduces the risk of slipperiness.
Conclusion
Choosing the right cleaner for your sealed concrete is crucial to maintaining its appearance, durability, and safety. By understanding the different types of cleaners available and what to look for when selecting a product, you can ensure your sealed concrete remains clean, protected, and looking its best. Remember to always follow the manufacturer’s instructions, take necessary safety precautions, and test a small area before using a new cleaner. With the right cleaner and proper cleaning techniques, your sealed concrete will shine on for years to come.
