Chlorine is the enemy of stainless steel
Stainless steel and chlorine do not belong together. Quite the contrary. We can safely say that chlorine and chlorine products are among the greatest enemies of stainless steel - certainly of the most commonly used quality, SS 304. We had assumed that this was generally known, but it seems not to be the case. And what happens when chlorine is used? Rust forms, as shown in the enclosed photo.
This is not a cause for panic but it does come as something of a shock, especially for disgruntled customers who might think they’ve been sold a lower-quality product.
