## Questions & Answers

**Q: Can this product be used in the toilet cistern?**
A: Yes we have used it in the cistern for descaleing. Best with hot water as works quicker but if left overnight it should do the job

**Q: Are there instructions in English on the bottle please? I have a clear glass kettle, am hoping it would be suitable for this?**
A: Yes & yes...I have a glass kettle (with blue LEDs) and I descale every month. it still looks pristine & the Kilrock hasn't damaged it at all.

**Q: Does it contain muriatic acid?**
A: There’s no Hcl in this , it’s just Formic acid (CH2O2)

**Q: Can this be used on plastic shower heads?**
A: Yes use it on the shower head all the time.   I put some hot water in a washing up bowl then the same amount of kilcock and soak the shower head.
