Black Spot Cleaner Reviews

Not all black spot cleaners work how they say they do…

Universeal supplies a range of high-quality outdoor cleaners that are designed to completely eliminate patio black spot and other forms of stubborn red lichen, black lichen and other general dirt and grime.

We’re proud of the reputation we’ve built up since forming in 2008, with all our outdoor black spot cleaners being developed, bottled and shipped from our facility in Dorset.

No More Black Spot is a professional-grade outdoor cleaner which eliminates all traces of stubborn grey, red, & white lichen and stubborn patio ‘black spot’ from all masonry and natural stone surfaces.

Another benefit of our market=leading black spot cleaner is that it deep cleans the natural stone surface and seriously restores faded colour. Check out some of the before and after photos below to see how transformative the effect can be!

I use the Universeal range for my outdoor cleaning business and the results are consistently excellent. All lichen gone, natural colours back to new – so impressive!

After 20 years our Indian Sandstone was looking quite sad for itself, with little variation in coloration and much of the natural beauty of the stone hidden. We tried a few cleaners and regularly pressure washed the patio, but stubborn black spot remained. After applying “No more black spot” the majority of the original beauty has been restored!

I would like to give it 6 stars! I never give a review 5 let alone 6. I have been cleaning my slabs using high powered jet washes and bleach for 7 years and was unable to shift the black spots.
