Sodium Hypochlorite
I’ve purchased this several times recently for cleaning brickwork and paths around the house. It’s removed all the algae and black spots from the patio and brought it back to its original condition. It’s the only chemical I’ve found to give these results having tried all the other brands of patio cleaner. Even had friends and family asking where I got this from has they were impressed by the results
