“Amazing ! My patio was absolutely covered with black spots which my husband said I would never get rid of ! Determined to prove him wrong I pressure washed the patio first to get rid of the grime and then used the spot remover scrubbing bad areas as I went along . By the next morning most of the spots had gone ! I did give some patches a second go but honestly it looks like a new patio ! Don t lose heart if when you put it on the black spots remain . Just give it a scrub and leave overnight . DON T apply in the sun as product dries too quickly before it has had chance to work . A dull day is better .”
“Did all that what promised, with the added bonus that, unlike pressure washing, the mortar wasn't blasted out from between the paving slabs. Very happy”
