## Questions & Answers

**Q: Can this be used in an outside drain with some food/fat debris?**
A: Hi Katie. 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.
