Review: Tested and tough—caustic soda clears drains fast, but demands respect and proper handling. - Used it on a blocked kitchen sink and a slow-draining outdoor gully—this stuff works fast. Mixed 100g with 1L of cold water, stirred until dissolved, and poured it straight down. Within 10 minutes, you could hear it fizzing and shifting the blockage. Followed up with hot water and the flow was back to normal. It’s industrial strength, so you need gloves, goggles, and ventilation. The powder reacts aggressively—don’t mess about. It also works well for degreasing tools, cleaning brickwork, and prepping surfaces before painting. I used it to strip grime off a concrete pad and it lifted years of buildup in one go. Packaging’s basic but solid. Lid seals tight, no leaks. Just keep it dry and locked away—this isn’t something you want kids or pets near. ✅ Pros Fast-acting—clears tough clogs in minutes Versatile—drains, tools, brickwork, degreasing Industrial-grade strength for serious jobs Affordable—around £8–£9 for 1KG1 2 3 4 Easy to mix and apply Long shelf life if stored properly ❌ Cons Highly caustic—needs full PPE and careful handling No childproof lid Can damage pipes if misused—follow instructions Not suitable for aluminium or soft metals Review: Cleared some of the blockage - This seemed to help the blockage.

Ours was used for the upstairs sink, you can try it but i expect you'd need a heavy duty one.. **Q: Is this pure caustic soda powder with no extra ingredients added?** A: It is Caustic Soda and works extremely well for overnight drain unblocking but it is not pure Sodium Hydroxide. So, don't use it for food grade purposes. **Q: Can it be used to make soap** A: This is not to my knowledge used to make soap you can use it as a cleaning solution but it must be a very diluted with water and always wear gloves, I've used it to clean paint work. Be cautious ⚠️ **Q: Is this a powder?** A: Yes, this is a powder that you mix with cold water. The water then gets warm to hot before it goes down the drain. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Tested and tough—caustic soda clears drains fast, but demands respect and proper handling. *by G***E on 24 September 2025* Used it on a blocked kitchen sink and a slow-draining outdoor gully—this stuff works fast.
