This Fossil Mint Sandstone Paving was laid more than 10 years ago, on our landscaping display area. Previously it was occasionally cleaned using a high pressure washer, but we found that it was not suitable for removing the accumulating black spot that blights many patios in the UK. We set to work to find the best product for cleaning the patios we sell to our customers. Rob Parkers Best Patio Cleaner is the most effective patio cleaner for the removal of Black Spot
We have developed our own formulation of Patio Cleaner which effectively removes black spot as you can see here.
Rob Parkers Best Patio Cleaner has been developed by scientists after researching the best way to kill the lichen to prevent new growth, and also the rbest way to remove the existing marks.
Rob Parkers Best is a biocide which will get into the growth & kill the Black Spot permanently, but also has a bleaching agent which will bleach the blackness out of the visible Black Spot.
To work properly it is necessary to ensure that the Rob Parkers Best Patio Cleaner remains on the affected stone for at least an hour, and that during the treatment period the stone surface remains wet.
After treatment the biocide will have killed all the Black Spot spores, preventing new growth from occurring in the future, plus most of the remaining dead black spot deposits will not be visible as the chlorine content will have bleached them.
Sometimes, particularly stubborn deposits will remain on the stone after treatment.
Rest assured, that over time, now that there is no live lichen in the stone, these (bleached) dead deposits will loosen, and the next time the patio is power washed, any remaining lichen deposits will be removed and the stone surface will become as clean and brilliant as it was when first laid.
Give it a try, it really works!
If Black Spot is not your particular problem, we have other products which may be better suited for your situation, such as
which will remove the build up of green deposit that accumulates after the winter or in particularly shady or damp conditions.
