## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great stuff
  

*by L***Y on Reviewed in the United Kingdom on 10 May 2023*

I’ve tried pretty much everything, natural and unnatural, to clean up the marks on my sink over the past few months. Finding this, I was skeptical but also hopeful as I’ve had great results with Oust in my kettle in the past, and the brush element of it looked great. I only had to leave it on for a minute or so and the shine is amazing. Absolutely recommend!

    Good and easy to use
  

*by E***K on Reviewed in the United Kingdom on 18 December 2021*

Lifts limescale, leaving surfaces on sink, drain board and taps with a good shine. Smell is awful, though.Works, so I do recommend.
