In one project we were tasked with improving a process of removing a scale/debris from laser-cut CoCr parts. It became apparent that, while CoCr is corrosion-resistant (meaning: chemically-resistant) the scale was even harder to attack. Only very aggressive chemistries worked and they had to be mixed fresh on-site, because they were reactive and unstable over time. For us, the chemical vendor, such situations present a challenge – we want a product with a decent shelf-life, stable over time. And we did not have a product for this customer at the time. However, sometime later, through experimentation, we developed a new product: CoCr Cleaner II, which is stable to ship and store, yet cleans the CoCr scale quite well.
