BEWARE: New formula, less effective
on August 31, 2015
I've been using this product in my espresso machines for years and it was quite apparent it has undergone a formula change (without notice.) The smell of sulfur is gone and dissolved calcium particles are no longer seen being expelled from the machine. This is very concerning because it could permanent damage the machine. I've contacted the company to inquire if this is the result of some EPA mandate and to ask what changed. The MSDS sheet has changed as well so something is definitely different here. I will update if I receive a notable reply from cleanright.
