BLACK SPOTS GONE, COLOUR RESTORED: Patio Black Spot Remover is a ready to use patio cleaner for man-made paving. It clears black lichen, white fungi and algae, bringing back the original colour of your slabs without harsh scrubbing or acid MADE FOR ARTIFICIAL STONE: Formulated for concrete, precast and reconstituted stone, this patio slab cleaner also works on porcelain, resin driveways and brickwork. You can even use it on house walls by applying it in light coats POWERFUL BLACK SPOT REMOVER: It works deep into the surface to clear the black spots, bird droppings and berry stains that pressure washing alone can't shift. Rinsing is then quicker and safer, with less risk of damaging the slabs or loosening the pointing GARDEN AND PET FRIENDLY: The biodegradable, acid-free formula can be rinsed safely into flower beds and over the lawn. Keep pets away while the product works. Once it has been washed off, pets can walk on the area again, which makes this a pet friendly patio cleaner for family gardens EASY TO USE, NO MIXING: Pour it neat into a pump-up garden sprayer (not included), spray it onto dry paving, leave it for 2 hours and then pressure wash it off with a fan jet. One 4 litre bottle treats up to 20m². Treat one slab first, as older or heavily stained paving may need more than one application for the best results
