### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Effective product - easy to use
  

*by A***R on Reviewed in the United Kingdom on 10 March 2021*

After cleaning my patio with a pressure washer, I was left with lots of black spots and marks on the paving stones.  I used the One Chem Black Spot Remover on the patio and left it for 2 hours as specified.  I then recleaned using the pressure washer and the majority of the spots have now gone.  I made sure that the patio was in the shade when I applied the remover to ensue it did not dry out.I would recommend it.

*by A***R on Reviewed in the United Kingdom on 16 May 2021*

This did exactly as it says, it removed all our black spots from our large Indian stone patio and left it like new, I did it about 8 weeks ago now and it is still looking great.

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Contents get 5 stars; container gets 1 star.
  

*by N***T on Reviewed in the United Kingdom on 3 May 2021*

The twist safety cap (which was white; not red as shown in the description) could not be removed after trying for 30 mins. Resorted  to puncturing it to pour the contents out of the container. However, the contents did what I expected & I was very pleased with the result.
