Water spots on refrigerator there I get water & ice

I use vinegar

I'm not sure if its safe to use on stainless (so check the box before using) but the ERASER pads that remove scuffs marks, crayon etc might work. If that does remove the spots, you might try putting a tiny bit of oil, only on the problem area to create a barrier. I would say coconut or at least an oil that won't get sticky. Maybe test on the back of fridge first. I suggest this because my father in law, who laid tile etc for many years, told me to use lemon old English liquid furniture polish and rub over new grout, let it set then rub off excess to prevent calcium build up and mold. I wouldn't use the polish on the fridge though! : )

plege will polish

I also have a Samsung "stainless" refrigerator, as well as a dishwasher, that gets plenty of water drip lines. I spray with white vinegar and use a microfiber cloth to rub off. If the water streaks stubborn, I let the vinegar sit for a few minutes before wiping off
