**Q: Is this product pure sodium hydroxide? If yes, can I know what is the concentration of the same?**
A: I do not know the concentration

**Q: What is the purity % of this caustic soda? Also if this can be used in soap, why is it not mentioned in the description.**

It's meant to clean rough stains on appliances and utensils, such as lard, hardened oil, etc.

**Q: Can I use this for parking tiles**
A: I USED IT FOR DE-GREASING MY KITCHEN CHIMNEY COVER AND IT WORKED VERY WELL. NO SCRUBBING NEEDED AT ALL.
I HAVE NOT USED ON TILES. I THINK IT SHOULD WORK ON TILES TO DEGREASE THEM EASILY.
NOTE: AFTER OPENING THE BOTTLE MAKE SURE TO COVER IT IMMEDIATELY, AS CAUSTIC SODA BEING HYGROSCOPIC, WILL ABORB MOISTURE FROM AIR AND DISSOLVE IN IT. ALSO IT WILL DESTROY THE PLASTIC CONTAINER.
