Why do brown or black spots appear on the surface of the dish stand wire?
This is a situation where someone was examining a new dish stand, discovered traces such as dark spots or smudges on the wire exterior, and wants to check if it is a product defect or contamination.

These are natural traces created during the processing stage of coating the wire with transparent polyethylene and heat-treating it; it is not corrosion or a defect, but an inherent characteristic of normal products.
The brown or black spots appearing on the stainless steel wire surface of the Kajidonya dish stand are normal product characteristics that occur during the heat treatment process of the transparent polyethylene coating[1].
To reduce friction against dish surfaces and prevent scratches, kitchen wire products are coated with a thin polymer resin over stainless steel and then heated to adhere tightly. In this processing stage, contact with high heat can leave fine dark traces near the transparent film. Because this is not rust caused by external contamination or corrosion, there is no need to peel it off and you may use it with confidence[2].
The maximum heat-resistant temperature of the transparent polyethylene coating or the specific thickness specifications of the wire have not yet been confirmed.
