Thanks Gerald, that seems to make sense but it seems that it only happens to the OP when he does full bleaching but not partial bleaching and I cannot see how this is related. Maybe it is less a question of full bleaching and more a question of time since full bleaching will take longer as will full toning afterwards
My other conclusion from what you have said is that it would also seem that if the water isn't hard then the haze won't happen. I have no idea how hard the water is in Toronto.
The whole business of haze in relevant to me as in my part of the U.K the water is also classified as hard but there is hard and hard and Toronto water may have my water well beaten in the hardness stakes
Am I on the right lines with my thoughts?
