Clean a stainless steel sink with a soft cloth, warm water and a mild cleaner, working in the direction of the brushed grain rather than across it. Steel wool, wire brushes, bleach and abrasive scourers all count as damage rather than cleaning: they leave micro-scratches that dull the finish and, on anthracite models, can cut through the nano coating to the steel underneath. This guide covers the daily wipe-down, the weekly deeper clean, and what to avoid on both plain and coated finishes.

What should you do after every use?

Rinse the sink and wipe it dry with a cloth after every use, because standing water is the single biggest cause of water spots and mineral buildup on stainless steel. Hard water leaves a chalky residue as it evaporates, and left long enough, that residue etches into the surface and becomes harder to remove. The habit takes under a minute and prevents most of the buildup that a deeper clean later has to work through.

How do you remove everyday grime and stains?

Sprinkle baking soda over the damp sink, scrub gently with a soft sponge or non-scratch pad in the direction of the grain, then rinse and dry with a clean cloth. Baking soda is mildly abrasive enough to lift grease and food residue without scratching the steel, unlike scouring powder or steel wool. For a fresh scent alongside the clean, add a squirt of washing-up liquid to the baking soda paste before scrubbing.

How do you remove hard water stains and limescale?

Apply a paste of white vinegar or lemon juice directly to the stained area, leave it for a few minutes, then scrub gently and rinse. The acidity dissolves mineral deposits that baking soda alone won't shift. For a stubborn build-up, a specialist stainless steel cleaner such as Bar Keeper's Friend works, provided it's rubbed in the direction of the grain and rinsed off fully rather than left to dry on the surface.

What should you never use on a stainless steel sink?

Never use steel wool, wire brushes, bleach or chloride-based cleaners on a stainless steel sink, because all four damage the surface in ways that are difficult to reverse. Steel wool and wire brushes leave scratches and can deposit tiny iron particles that rust on contact with the stainless surface, showing up as orange spots that are surface contamination, not rust in the steel itself. Bleach and chloride-based products attack the chromium oxide layer that keeps the steel from corroding, and repeated use leaves the surface duller and more stain-prone over time.

Does an anthracite finish need different cleaning from plain steel?

Yes, an anthracite finish needs gentler cleaning than plain steel, because the nano coating sits on top of the base metal and abrasive pads that are safe on bare stainless can dull or scratch the coating itself. Stick to a soft, damp cloth for anthracite and nano-coated finishes, skip the baking soda scrub that works fine on silver models, and avoid bleach entirely. Every RUMO sink, coated or plain, ships with the same underlying instruction: wipe with a soft, damp cloth, and avoid abrasive cleaning products.

How do you finish and add shine?

Buff the dry sink with a few drops of olive oil on a lint-free cloth, working in the direction of the grain, to bring back shine and leave a light film that resists new water spots. This step is cosmetic rather than essential, but it's the difference between a sink that looks clean and one that looks new. Skip this step on nano-coated anthracite finishes, since oil can sit unevenly on the textured surface rather than the smooth satin steel it's designed for.

Getting the material grade right at the point of purchase makes this whole routine easier. SS304 steel resists staining better than cheaper grades to begin with, so the same weekly clean keeps a RUMO sink looking new for longer than a budget alternative.
