Hi, have a number of jobs on a recently constructed site with some building still going on. Have several customers who complain that water running down off brickwork leaves all stains and smears after we finished. Anyone know what this might be and anything we can use to get rid of it. Doesn't seen to happen on jobs been doing for a while

Thanks Stephen

If its effloresence then brick-acid will be ineffective, its the salts from the mortar leeching out, it'll keep leeching until theyre gone.
