BLACK SPOTS GONE, COLOUR RESTORED: Patio Black Spot Remover is a ready to use patio cleaner that clears stubborn black lichen, white fungi, green and red algae from natural stone. It brings back the original colour of your patio, paths and steps without harsh scrubbing or acid MADE FOR NATURAL STONE: This specialist natural stone cleaner is suitable for Indian sandstone, Yorkstone, limestone, granite, marble and travertine of any age. Use it as an Indian sandstone cleaner, a patio stone cleaner or a paving slab cleaner, without the risk of etching that acid-based products can cause POWERFUL ALGAE REMOVER: It works deep into the stone to clear the black spots that pressure washing alone can't shift. As a lichen remover and green algae remover in one, it quickly lifts dirt and grime so your patio, garden path and outdoor walls look like new again 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 stone, leave it for 2 hours and then pressure wash it off. One 2 litre bottle treats up to 10m². Treat one slab first, as older or heavily stained stone may need more than one application for the best results
