Drug Residues: MgO and Ca2SiO4
Our CIP system is struggling with a new product leaving drug residues of magnesium oxide and calcium silicate. We recently switched from a competitor to Solujet which worked very well but not on this newest product. What should we be doing?
Cleaning Seaweed Harvest Materials
Q: How should we remove dirt, oils and greases from lines, ropes and netting in the ocean used in seaweed harvesting?

A: First, as we always ask, is this process working? Is the flux being removed? Is there darkening or oxidation occurring on the parts? Critical cleaning is of course a science. There is also an “art” component to it in that….
