TL;DR
White spots and a dull film on flatware are hard water minerals left behind as droplets dried. A five to fifteen minute soak in a mix of white vinegar and water dissolves them, and a hand dry with a soft towel prevents the next round. The habit matters more than the treatment, because spotting happens during drying, not during washing.
What the Spots Actually Are
Tap water carries dissolved calcium and magnesium. When a droplet evaporates, the water leaves and the minerals stay, deposited as a white ring or a chalky haze.
Nothing is stuck to the metal chemically. It is a deposit sitting on the surface, which is why an acid removes it easily and why scrubbing feels like it should work but only spreads it around.
Much of the Willamette Valley has moderately hard water, and homes on a well often see much harder. The harder the water, the more visible the film after every wash. The same mineral behavior shows up on cookware, as covered in why stainless pans get chalky white spots, and the material rules across a whole kitchen are in the guide to cookware and glassware care by material.
How Do You Remove Water Spots From Flatware?
Soak the pieces in a bowl of equal parts white vinegar and warm water for five to fifteen minutes, then rub each piece with a soft cloth, rinse in clean water, and dry immediately with a soft towel. Mineral deposits are alkaline, so a mild acid dissolves them quickly with no scrubbing required.
For heavy film, warm the vinegar solution first. Warm acid works faster.
Lemon juice does the same job. So does a mild cream cleanser rubbed on with a soft cloth, though that is more work for the same result.
Stainless, Silver, and Silver Plate Are Not the Same
Stainless steel flatware handles the vinegar soak without any concern. Rinse and dry it and it will be bright.
Sterling silver and silver plate need more care. A short acid contact is generally tolerated, but silver's real enemy is tarnish, which is a sulfur reaction and needs a silver polish rather than vinegar. Never leave silver soaking in an acid, and never use an abrasive on silver plate, since the plating is thin and comes off for good.

Silver also should not sit in contact with stainless steel in a wet environment, because the two metals in the same water can drive a reaction that pits and marks the silver. Wash them separately.
Why Do Spots Show Up Even From the Dishwasher?
Because the dishwasher uses the same hard water, and spotting forms during the drying phase as droplets evaporate on the surface. A rinse aid helps by breaking surface tension so water sheets off instead of beading. Unloading while the load is still warm and hand drying the flatware also eliminates it.
Overloading the flatware basket is a common cause too, since pieces nesting together trap water between them.
Put flatware in the basket with a mix of handles up and handles down so pieces do not spoon together. Some baskets are designed for handles down, which cleans better but means touching the eating end when unloading.
What Not to Do
Never use chlorine bleach on flatware. Chloride attacks the protective layer on stainless steel and causes permanent pitting, and it tarnishes silver badly.
Never mix bleach with vinegar, which releases chlorine gas, or with ammonia from a glass cleaner, which releases chloramine gas. There is no reason to have bleach anywhere near this job.
Skip steel wool and gritty powders. They will remove the film and leave a scratched, dull finish that shows every future mark.
Do not leave flatware sitting in the sink in water, especially with salty or acidic food residue. Extended contact with salt and acid pits stainless and stains it in ways that no soak will fix.
Rust Spots and Pitting on Stainless Flatware
Small orange or brown specks on stainless flatware usually come from other rusting objects in the dishwasher, from prolonged contact with salt, or from cheaper alloys.
A paste of baking soda rubbed on with a soft cloth removes surface rust spots on stainless. Pitting, which is a small crater rather than a surface mark, is permanent.
The prevention is the same in every case: rinse food off promptly, do not let pieces soak, and dry them.
The Habit That Actually Fixes It
Hand dry. Almost every spot forms as water evaporates, so removing the water removes the problem.
Rinse in the hottest water you can handle before drying, since hot water evaporates faster and leaves less time for minerals to settle.
Store flatware dry in a drawer tray rather than damp in a caddy. Silver needs the extra step of a tarnish barrier, which how to store silver flatware so it tarnishes slower covers, and the drawer or block holding your knives needs its own attention, described in how to clean a knife block and the narrow slots inside. When mineral film is showing up on fixtures and shower glass around the house too, scheduled house cleaning services handle those surfaces on their own schedule.
FAQ
How do you get water spots off silverware?
Soak the pieces in equal parts white vinegar and warm water for five to fifteen minutes, rub each one with a soft cloth, rinse in clean water, and dry immediately with a soft towel. The deposits are alkaline minerals, so a mild acid dissolves them without any scrubbing.
Are water spots on flatware harmful?
No. They are calcium and magnesium from tap water, the same minerals already in your drinking water, left behind as droplets evaporated. They are purely cosmetic, though a heavy film can dull the finish and make the flatware look permanently stained when it is not.
Can you use vinegar on silver flatware?
Briefly and carefully. Sterling and silver plate tolerate short acid contact, but silver's main problem is sulfur tarnish, which needs a silver polish rather than vinegar. Never leave silver soaking in acid, and never use an abrasive on silver plate, since the plating is thin.
Why does my flatware come out of the dishwasher spotted?
Because spotting forms during the drying phase as hard water droplets evaporate on the surface. Use a rinse aid so water sheets off, avoid overloading the basket so pieces do not nest and trap water, and unload while the load is warm so you can hand dry.
Can you mix silver and stainless flatware in the dishwasher?
It is better not to. Silver and stainless in contact in the same water can drive a reaction that pits and marks the silver. Wash them in separate loads, or at least keep them in separate compartments of the basket so they never touch while wet.
What are the orange spots on my stainless flatware?
Usually surface rust picked up from another rusting item in the dishwasher, from prolonged contact with salt, or from a lower grade alloy. A baking soda paste rubbed on with a soft cloth removes surface rust. A pit, meaning an actual small crater, is permanent.
Does bleach clean flatware?
No, and it damages it. Chloride attacks the protective layer on stainless steel and causes permanent pitting, and it tarnishes silver. It is also dangerous mixed with vinegar or with ammonia from glass cleaners. Use a vinegar soak for minerals and dish soap for everything else.
