No type of flooring material is truly maintenance-free, and same holds true for cemented floors.
In fact, you might have often seen white stains on cement floors. These are formed due to a chemical reaction called ‘efflorescence’. In this reaction, calcium hydroxide from the cement reacts with the carbon dioxide in the atmosphere to create a water and calcium carbonate salt, which forms white stains.
To remove these, you need a cement specialist such as Lizol Cement Surface Cleaner. Its 3in1 power penetrates the pores on the cement floor, dissolves and eliminates the white stains along with removing 99.9% germs.
Use regularly for 6 days as per instructions on the pack to see visible results.
