« on: November 15, 2007, 09:43:26 pm »
could not get lichen patches off yorkshire paving with just cold water pressure washer, think i need a chemical that does not fade the flags.   the lichen is not in spots like on normal flags its in big black patches where bushes used to cover them its murder to shift! ???  anyone done this before!

Try a product called "Lichenite"
