Comparison Natural Stone Artificial Stone Block and Brick Paving Preventer Stone King 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: Amazing product. - Absolutely incredible result. My 17 year old patio was covered in black spots and grime I have pressure washed if every year but that does not remove black spot. After using Black Spot remover it is almost back to how it was after it was laid. It is so easy to apply with amazing results. It is expensive, I need 3 x 4 litres as it is 40 square metres but it was definitely worth the cost. ## Features - PATIO SPOT CLEANER - Our black spot and dirt remover is formulated specifically to effectively remove black lichen, white fungi, green & red algae, and restore your garden stonework to its former glory. - NATURAL STONE CLEANER - Specifically designed for natural stone, this product removes stubborn organic growth including stubborn black lichen and green algae, ensuring a thorough clean without damaging the stone surface. - RESTORE COLOUR - This patio cleaner gently revitalises natural colours, lifting stubborn organic matter effortlessly, thereby helping to maintain the longevity of your garden stonework. - GARDEN AND PET FRIENDLY - Our paving slab cleaner for natural stone is biodegradable and acid-free patio cleaner.
