## Customer Reviews

### ⭐⭐⭐⭐⭐ Cheaper elsewhere!
*by M***. on 30 January 2025*

This is a must-use item for irons etc in hard water areas and also gives a better finish on window cleaning we have found but it is much cheaper to buy it from Tesco. I only bought this online because Tesco had no stock at the time.
