Floaties in Sani-clean

I was going to add on to the cloudy star-san thread, but I think this is a little different.

I like to us sani-clean (the no-foam version of star-san) for certain applications, but I have noticed that if it sits for a few days in a covered bucket, floating coagulated parts form. I am not sure what it is, but I don’t like it. They mostly seem to settle down to the bottom of the bucket, but are easily roused. The pH is still in the appropriate range for effective sanitation, but I would like to know what this stuff is, and if it affects the normal usage of the product.

Any ideas?

It must have something to do with the mineral content of the water. Saniclean will cloud up on me after a day or two when mixed with Chicago tap water. It will stay clear if I use distilled (dehumidifier collections) water.
