Patio Black Spot Remover is currently the only product developed specifically to safely remove staining caused by black spots and restore the natural colour to garden stonework. Patio Black Spot Remover will remove stains caused by black spots from all types of stone, including stains caused by green algae and stains caused by white spots.
Garden stonework adds a unique and beautiful touch to any outdoor space, but with repeated exposure to the elements, it is prone to developing black spots and green algae over time. Using Patio Black Spot Remover will help maintain the life of your garden stonework, including your pointing. When you rely on pressure to clean your stonework, you're damaging the surface of the stone whilst helping to dislodge the pointing. Patio Black Spot Remover gently restores the natural colours and lifts dirt and grime effortlessly, making pressure washing effortless.
To maintain your garden stonework and stop the return of black spots, buy and apply our Patio Black Spot Preventer annually. This will remove any black spot spores before they have the chance to germinate and turn into spots. It will also remove green algae without the need to power wash! The Preventer does not need to be applied until 12 months after the initial Patio Black Spot Remover process.
If you have flowers and other plantings stationed around your patio, you won’t have to worry about our products affecting them. Patio Black Spot Removal products are biodegradable and acid-free, allowing you to wash the product in a diluted state into the flower beds and over the lawn without causing any harm.
The coverage rate is based on a patio that is 3 years old. The older the stone, the more treatments will be required. Carry out a trial slab first to determine the coverage on your stonework.
Shop our Patio Black Spot Remover today and enjoy a hassle-free solution to remove unsightly stains and discolouration.

"Excellent product! Worked perfectly to remove all the black lichen from my slate patio and allowed me to DIY a job that likely would have cost thousands for someone else to do. Instructions and videos were very helpful."
"Great i tested three other products on some bluestone that had liken. But black spot remover only one that worked. Going to order for this job. Called your customer service gave all the info. I needed. Thanks, Bob Wilson Seal Team One Washington State , US"
"This product works as claimed. Cleaned our slate walkway as no other product has with minimal efforts. We will definitely purchase again."
"LOVE the Black Spot Remover!! Very easy to apply and rinse off. Our flagstone patio looks like new! Highly recommend!!"
"Husband loves it"
"Second time using this product 👍"
"Did not get as clean as expected. Needed more"
"It removed the black spots but did nothing to remove the yellow algae on my bullet edgers, bricks and concrete. Great if you just need black spot removal."
"This works like they say"
"It works fantastically. In some spots even if I do it through four times it doesn't remove it completely but 95% of the spots it does a phenomenal job. I have been telling everybody about it. It's well worth it. Even though I wish it was a little less expensive. Nothing works like your product. Steve Sullivan"
1. Use neat – DO NOT DILUTE – Pour our solution into a pneumatic garden sprayer. (A ‘Hozelock’ 5L or 7L sprayer or similar is recommended. Do not use a small trigger sprayer.) Pressurise the sprayer.
2. Apply the product as a fine mist to a dry surface, and saturate the surface.
3. 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. By completing one slab first, this will give you an indication of how many treatments your stone will require. Only when you have removed all the black spots from the first slab, continue with the rest of the area.
4. DO NOT EXCEED THE MAXIMUM RECOMMENDED COVERAGE OF 5 SQM PER EACH 1L OF PRODUCT.
5. Once applied, allow to cure for a period of 2 hours.
6. Remove using a pressure washer. Use the fan jet attachment to sweep the dirt away. Other attachments such as circular spinning attachments will not give you the best results.
7. Any black spots that remain, simply retreat (when the surface is dry) allow to cure for 1 hour then wash off.
8. Repeat this process until no black spots remain.
9. Apply the Patio Black Spot Preventer 11-12 months later. Do not seal the patio.
Exceeding the recommended coverage rate will reduce the performance of this product. Coverage will vary depending on surface porosity and profile, e.g when treating sloping areas or riven surface, beware of surface run off and retreat as necessary to ensure correct coverage.
The Patio Black Spot Remover is quickly and readily biodegradable. The effluent if washed into soil, flower beds or lawn will breakdown rapidly. This product will not affect surrounding lawns or foliage in diluted state. Keep animals and unprotected persons off the treated area until dry.
