For use as a Patio Cleaner & Moss Remover

Apply the solution and leave and within minutes you will see the results.  Take the hard work out of cleaning drives, block paving, fences, walls, stonework, brick work, paths, patios, decking, gravelled areas and even roofs!   Usually a maximum solution of 50% will be more than effective.

  2. Adrian (verified owner)

    Used it to clean my patio. Cleared the patio of debris, poured on the liquid and left for 20-30 minutes then brushed off using a conservatory roof brush attached to a hose pipe. Came up like new.
