Hello, stainless steel does not mean that the product will not rust. It's a generic name given to stainless steel. The various elements such as Nickel, Chrome, Molybdenum, Carbon, Manganese found in steel products form the product's steel numbers like 201-410-304-316-1010. According to the amount of these elements, the quality and type of material is formed. Therefore, steel products can react differently when they come into contact with various chemicals. It is more appropriate to wash steel products by hand as detergent, salt, and high temperature and water pressure may damage the product.
