## Description

Patio Black Spot Remover is currently the only product developed specifically to safely remove those hideous stains caused by black spots and restore the natural colour to garden stonework. Patio Black Spot Remover will remove stains caused by black spots, remove stains caused by green algae and staining caused by white spots from all types of stone. This product will also remove stains caused by mold & mildew. Directions:Use neat – DO NOT DILUTE – Pour our solution into a pneumatic garden sprayer. (A ‘Hozelock’ 5L or 7L sprayer is recommended. Do not use a hand sprayer.) Pressurise the sprayer.Apply the product to a dry surface, as a fine mist and saturate the surface.If you have not used the product before. Treat just one slab first. The older the stone, the more treatments it will require. The product will remove every single last spot. Completing one slab first will give you an indication of how many treatments your stone will require. Only when you have removed all the stains caused by black spots from the first slab, continue with the rest of the area.Do not exceed the maximum recommended coverage of 5 sqm per each 1l of product.Once applied, allow to cure for 2 hours.Remove using a pressure washer, ideally with a minimum flow of 7 litres per minute. Use the fan jet attachment to sweep the dirt away. Other circular spinning attachments will not give you the best results.Any stubborn staining that remain, simply retreat (when the surface is dry) allow to cure for 1 hour then wash off.Repeat this process until no black stains remain.Apply the Patio Black Spot Preventer 12 months later. Do not seal the patio.Ensure product doesn’t come into contact with skin, eyes or respiratory tract. In the event the product does come into direct contact with the body, immediately rinse with water. Ensure this product does not come into contact with fabrics or furnishings.

Review: Best stuff - I have a 5 acre estate customer, exspencive terra cotta colored sandstone paver patio. Had black lichen everywhere. After reading mixed reviews, I tried it. The secret, follow the instructions. Pay attention to your weather forecast. If you have rain within 48hrs, don't use it. It won't work. I used a spray bottles made for harsh chemicals. One generous pass in sunshine usually enough. I didn't rinse after 2hrs. Didn't have any issues.
Review: Works but very pricey - I had a bluestone cap on a pillar that was completely black. I used this and it got it all looking like bluestone again with no more black. However, I think the stuff that costs 1/5 as much that is available in hardware stores and big box stores would have done just as good a job. This definitely works but it's very pricey. I would have given it 5 stars if it weren't for the price.

### ⭐ Don't Waste your time and money!
*by A***L on June 22, 2025*

This product is a hoax. Nowhere on Amazon, nor on the product packaging, are the ingredients stated. The results are nothing like what is represented in their video. This product is essentially exorbitantly overpriced bleach. I accidentally got some on my black pants, which now have spots and are ruined - as it splashed with bleach. Don't be duped! This was a very expensive mistake - and of course, it's not returnable.
