Aye, been there but you will know what to do the next time. When you go to price the job make sure you have 5l hypo in the van and plenty of rags. If you get the job there and then, then see if there is any bad black bits and leave some neat hypo rags down or do the same when you turn up to do the job. By the time you are ready to go it has usually done its job. ?

Most folk think black lichen is apart of the Indian sandstone I have found out. tbh
