Comparison Natural Stone Artificial Stone Block and Brick Paving Preventer Stone King Review: Good product - leaves tiles looking new! - Works well, but you need quite a lot. (I used a 4L bottle for around 15-20sqm and will need another to finish the patio.) Easy application using spray hose - takes about 2 hrs to work before pressure washing. I kept topping up heavily stained parts during this time which were drying out quickly. Will need a second application in places to remove heavy markings. The smell is quite strong but dissipates overnight, and it will bleach your clothes and some grass alongside paths so don’t do it in your nice jeans! I think it’s the same chemical formula as bleach, just a lot stronger. Oh, and as someone else mentioned - remember to remove your shoes to avoid bleaching your carpets and floors ! 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. ## 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.
