Unitedlys® Caustic Soda Drainage Block Remover 350G | Fast-Acting, Non-Toxic & Odorless Drain Cleaner Powder | Caustic Soda for Drain Cleaning | Sink & Pipe Drainage Cleaner : desertcart.in: Home & Kitchen

Review: Effective Drain Cleaner but Use with Caution - The Caustic soda flakes worked very efficiently for clearing blockage, but please be very careful while using them . 🚨The smell is extremely pungent and irritating to the eyes and nose, so wearing gloves and staying in a venti what does ventilated what does ventilated area is highly recommended. For the best results, I use around 3-4 L of boiling hot water in a blocked pipe/drain first. Then I added about 2 lidfulls of the flakes from the container and left it around for 15-30 minutes. After that, I put more hot water and the blockage cleared completely. The water started flowing prefectly again without any issue

**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.
