Review: Extremely effective, but expensive for large areas - Exceptionally good at completely removing heavy black/grey stains from Eqyptian limestone, which had defeated pressure washing and scrubbing. Apply and watch the stains lift in real time, no other work required, slabs left looking like new. Must be applied neat, making it expensive for large areas - do a test beforehand to see how much you need and to avoid using too much.
Review: When you use the product where gloves & face mask - Amazing product! It works very fast and did an excellent job removing black spots and marks from my natural stone patio. The results were impressive, and the surface looks so much cleaner and brighter. Very effective and easy to use. I would definitely recommend this product! 👌✨

### ⭐⭐⭐⭐ Good product but doesn’t go very far
*by S***N on 21 May 2026*

Patio was not good to start with. Patches of black spot all over it. Must admit it did a very good job. But used whole container on small patio. Need to do it again. So would recommend it but it doesn’t go far
