Rust spots appearing on the front doors of my Bosch refrigerator
Stainless steel does rust - or at least that is the theory.
There is in fact two types of stainless steel; the original categorised austenitic which is instantly recognised due to it being unable to attract a magnet due to the absence of iron. Austenitic is relatively expensive and difficult to work but adding iron in various quantities to the alloy produces a cheaper, lighter metal that looks good and is easier to work while still providing some resistance to corrosion. The more iron that is added to the ferritic type of stainless, the lighter, cheaper and easier it is to work but the corrosion resistance is substantially reduced.
Cars have been fitted with stainless steel exhaust systems of the ferritic type for many years and although they last a long time they soon show surface rust and sometimes will rust through.
I expect your fridge wipes are either acid or alkaline that are suitable only for austenitic and good grades of ferritic and Bosch have used a particularly poor grade of stainless. I expect fridge magnets stick very well...
Mild discolouration could be removed with a mild abrasive cleaner though that would tend to ruin the brushed finish. Clearly future cleaning should be carried out with a neutral ph cleaner and the surface protected with a hard wax polish.
I suggest you check the cleaning instructions in the Bosch instruction book. If you feel you have done nothing wrong you might be able to claim from your household insurer as accidental damage. It would be a good idea to inform the manufacturer of the cleaning wipes...
