I am redoing my kitchen and looking for the best reviews of the various appliances. If I get them all in stainless, but from different manufacturers, will they match? Or do different companies have different stainless finishes that could clash?
Different companies and even lines within companies use various grades and finishes of stainless. There aren't so many that you can't get pretty good matches. A lot of appliances these days are white label and will actually be the same unit with different bezels. That is particularly true with front-load washers but is seen across the appliance industry.
