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.** A: Not meant for soaps. It's meant to clean rough stains on appliances and utensils, such as lard, hardened oil, etc. **Q: Can we clean bathrooms tap** A: You can use this product which is exclusively for Tap Cleaning. https://www.amazon.in/dp/B08XY4M2JZ?ref=myi_title_dp **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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by P***A on 26 February 2026* ### ⭐⭐⭐⭐ Review *by P***R on 3 December 2025* ### ⭐⭐⭐⭐⭐ Review *by A***A on 6 March 2026* ## Frequently Bought Together - Unitedlys Drain & Chimney Cleaner Flakes To Clear Clogged Sinks & Pipes 350 Grams (Caustic Soda) - Mr. Muscle Sink and Drain Gel Cleaner, Clear Blocked Sinks Fast, Works In 5 Minutes, 1L - Harpic Powerful Drain Opener Gel for Bathroom, Basins, Toilet & Kitchen Drains, 1L --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/120384178-unitedlys-caustic-soda-drainage-block-remover-350g-fast-acting-non](https://www.desertcart.vn/products/120384178-unitedlys-caustic-soda-drainage-block-remover-350g-fast-acting-non) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-04-25*
