Today's finishers are facing the reality of processing multiple substrates through the same line. This can be challenging since the acid descalers required for a high-quality finish with steel can harm softer metals like zinc and aluminum by over-etching them, leading to defects. Neutral descaling, however, can still give the expected performance on steel while not harming zinc and aluminum substrates. Learn about descaling challenges with multiple substrates and the pros and cons of implementing a neutral descaler to meet them.
