Preventing Rust on Stainless Steel Sinks
The best practice for homeowners is to wash the pot, dry it and remove it from the sink. By the same token, they should not open a can of vegetables or soup or the like and leave the empty can in the sink, or the tell tale ring could appear.
After sink use, homeowners should clean it with the appropriate cleansers and dry it after use; this will aid in keeping foreign particles from attaching to the sink and prevent the appearance of rust. Steel wool should never be used to clean a sink since it has a tendency to break apart and leave particles behind that will very quickly rust. Homeowners should also prevent allowing cleaners and abrasives from drying on the surface of the sink, as this can also lead to a degrading of the finish.
What if the sink has never been used, but displays small, pinhead-sized “rust stains” scattered all over it. How could this have happened, obviously the sink manufacturer must have produced a bad sink, right? WRONG. The real reason these rust spots have appeared is due to an installation issue that sometimes gets overlooked.
In order to fabricate the countertop, the installer uses a variety of tools most importantly the use of drill bits and blades made of very hard steel or coated in industrial diamonds. Sometimes after the sink is mounted in the countertop, additional tweaking is needed to ensure the radius or reveal of the sink is accurate. In doing so, blades and bits release small particles of foreign steel attach themselves to the surface of the sink and cause what appears to be surface rust. (Think of the saw dust that comes from a saw when cutting lumber.) Hopefully, when these types of installations take place, the installer knows to immediately clean the sink completely, but sometimes that doesn’t happen, and the customer is left with a sink that needs to be replaced.
