TL;DR
Fingerprints on stainless are body oil, so water alone will not lift them and glass cleaner just smears them. Wipe with a barely damp microfiber cloth and a drop of dish soap, always following the direction of the grain, then buff dry with a second clean cloth. Chloride bleach must never touch stainless, because it pits the surface permanently.
Why stainless shows every touch
Stainless steel is not actually smooth. It carries a directional brushed finish -- fine parallel lines running either horizontally or vertically across each panel.
Skin oil settles into those lines. Because the oil is transparent and slightly greasy, it bends light differently than bare metal, which is why a print stands out so clearly against an otherwise perfect panel.
That also explains why fingerprints come back so fast. There is no coating to prevent it on most appliances, and the finish that makes stainless look good is the same finish that holds oil.
Which direction does the grain run?
Look at the panel under a light at a low angle and you will see faint parallel lines. On most refrigerator and dishwasher doors they run vertically, and on ranges, hoods, and handles they often run horizontally. Wipe along those lines, never across them, or the cloth drags oil into the grooves instead of out.
The two-cloth method
The single most reliable way to get a print-free finish is two cloths, one damp and one dry.
Dampen a clean microfiber cloth with warm water and add one drop of dish soap. Wring it out until it is barely moist, not dripping. Wipe one panel at a time, moving with the grain in long overlapping strokes rather than small circles.
Immediately follow with a dry microfiber cloth, again with the grain, buffing until the panel looks even. Drying is not optional. Water left to evaporate on stainless leaves mineral spots, and those spots are what people usually mean when they say a cleaner "streaked."
Change to a clean section of cloth often. A cloth loaded with oil just redistributes it.

What not to use on stainless steel
Chlorine bleach and chloride-containing cleaners. Chloride attacks the passive chromium oxide layer that makes stainless stainless. The result is pitting and rust spots that cannot be polished out. This includes many bathroom cleaners and some disinfecting sprays, so read labels.
Abrasive pads and powders. Steel wool, green scrub pads, and scouring powder cut across the grain and leave scratches that catch light forever. Steel wool also leaves iron particles behind, which rust.
Ammonia-based glass cleaner. It evaporates fast and leaves a streaky film, and on appliances with printed control panels or coated displays it can damage the coating.
Anything applied across the grain. Even a safe cleaner looks bad if you wipe in circles.
Getting rid of grease, not just prints
Prints near the range are usually oil from cooking rather than from hands, and that is a tougher film. It has partially polymerized, which is the same process described in why kitchen grease is so stubborn.
For those panels, warm water with more dish soap and a two to three minute dwell does more than scrubbing. Lay a warm damp cloth over the greasy area, let it sit, then wipe with the grain.
If a haze remains, a small amount of isopropyl alcohol on a cloth cuts oily residue well. Use it in a ventilated kitchen, keep it off printed control panels, and never combine alcohol with bleach in any form.
Should I use a stainless steel polish?
A polish or a light oil helps in one specific way: it fills the grain slightly so new prints do not settle as deeply, and it evens out the sheen. Apply an extremely small amount, spread it with the grain, and buff until nothing feels slick.
Too much polish is worse than none. A greasy panel collects dust and shows every print, and it will transfer onto your sleeve.
Mineral oil on a cloth works about as well as a purpose-made product. So does a drop of olive oil, though it can go rancid over months and is better avoided in a kitchen.
Do not polish a stainless panel that has a factory smudge-resistant or fingerprint-resistant coating. Those finishes are not bare metal, and oil sits on top of them looking blotchy. Clean those with damp microfiber and dry buffing only, as covered in cleaning stainless steel appliances.
Rust spots and where they come from
Stainless can rust, and when it does, the cause is almost always something else. Iron particles from steel wool, a cast iron pan left wet against the surface, salt residue, or chloride cleaner all break down the protective layer.
Light surface rust often comes off with a paste of baking soda and water, worked gently with the grain using a soft cloth, then rinsed and dried. Do not use a wire brush.
For sinks, the same rule applies and the causes are similar, which is why a stainless steel kitchen sink needs drying rather than air-drying. While you are at the fridge, take thirty seconds for the refrigerator door gasket too.
FAQ
Why does my stainless steel streak no matter what I use?
Streaks are almost always leftover product or evaporated water. Cut the amount of cleaner in half, wring the cloth until it is barely damp, and finish with a completely dry microfiber cloth buffed with the grain. If a cleaner streaks every time, it is leaving residue and should be replaced.
Can I use vinegar on stainless steel appliances?
Diluted white vinegar is acceptable for occasional use on stainless and cuts mineral spots well, followed by a plain water wipe and a dry buff. Do not leave it sitting on the surface, and never mix it with bleach. For daily prints, soap and water works better because prints are oil, not minerals.
Do fingerprint-resistant finishes still need special care?
Yes, just simpler care. Smudge-resistant coatings are cleaned with a damp microfiber cloth and dried, and they should not be polished with oil, which leaves a blotchy film. Skip abrasives entirely, since a scratch through the coating cannot be repaired.
What is the best cloth for stainless steel?
A flat-weave microfiber cloth, sometimes sold as a glass or polishing cloth. It grabs oil without leaving lint. Waffle-weave and terry cloths hold too much water, and paper towels shed fibers that get caught in the grain and look like streaks.
Can I use a disinfecting wipe on my stainless refrigerator?
Check the label for bleach or chloride first, and skip any that contain them. If the wipe is chloride-free, follow it with a plain damp cloth to remove residue and a dry buff. Remember that disinfectants only work on a surface that has already been cleaned.
How do I remove sticker residue from stainless?
Warm soapy water and a plastic scraper first. If residue remains, a little isopropyl alcohol or mineral oil on a cloth softens the adhesive. Rub with the grain, then wash the area with soap and water and dry it. Never use a razor blade or an abrasive pad.
