The Right Cleaner
Is Your Cleaner Safe for Concrete?
Your cleaner may be unsafe if it:
- Contains acids, hydroxides or sulfates
Concrete is sensitive to acid which can lead to etching and staining. Sulfides and hydroxides will eventually soften concrete.
- Has a pH level above or below 9-10
A safe concrete cleaner is not neutral (7), but rather similar to the pH of cured/aged concrete (9-10). An overly acidic or basic cleaner can etch concrete.
- Contains acids, hydroxides or sulfates
