Clean matte black or brushed nickel faucets with a soft cloth and mild dish soap, then rinse and dry. For hard water spots, most makers allow a 50/50 white vinegar and water wipe, rinsed off quickly. Never use abrasive pads, bleach, ammonia or lime scale removers, which can damage the finish and void the warranty.
The safe cleaning routine for both finishes
Start with the gentlest method that works, and dry the faucet when you're done. That covers most of the job.
### Everyday cleaning, step by step
- 1Wet a soft cloth with warm water and a drop of mild liquid dish soap. Moen's care page describes a damp cloth and mild liquid dishwashing soap for all of its finish types.
- 2Wipe the faucet gently. No scrubbing. Work around the base, handles and spout tip where water sits.
- 3Rinse with clean water. Moen says all cleaners should be rinsed off thoroughly with water immediately after cleaning.
- 4Blot it dry with a soft cloth. Delta says to "Always blot dry any water from the faucet surface," because letting water evaporate on the surface can lead to mineral deposits. Kohler's faucet maintenance guide recommends a dabbing action to dry metal, not an abrasive or rubbing action.
That's it. Do it once or twice a week and you'll rarely need anything stronger.
### Removing hard water spots
In the Phoenix area, dried water leaves minerals behind fast. When the spots won't wipe off with soap:
- 1Mix equal parts white vinegar and water.
- 2Wet a soft cloth with it and wipe the spotted areas. Pfister's support page describes exactly this: a 50/50 warm water and white vinegar solution applied with a soft cloth.
- 3Keep it brief. Moen's instructions for its powder coat finishes, which include Matte Black, say the vinegar blend "can also be used for a limited amount of time, followed by rinsing with water and drying with a soft cloth."
- 4Rinse and dry. Delta says to rinse the surface thoroughly with water afterward.
For buildup around a handle base, Kohler Assist describes soaking a towel in a 50/50 white vinegar and warm water solution and wrapping it around the handle's bonnet or skirt for about five to ten minutes.
Delta also names a few store-bought cleaners that are safe on all of its finishes when used as the label directs: Formula 409 Antibacterial All Purpose Cleaner, Fantastik All Purpose Cleaner, and Windex Original Glass Cleaner.
### Wax: an optional extra for brushed finishes
Moen suggests the periodic application of a quality non-abrasive wax, such as car wax or furniture wax, "especially for matte or textured finishes" such as its Brushed Nickel. Moen notes wax will cause a slight color change but won't harm the finish, and suggests testing it on a less visible spot first. It's optional.
Finish by finish: what each brand allows and bans
Here's the part most cleaning guides skip. "Brushed nickel" and "matte black" aren't one material. Brands make them different ways, and the rules change with them. Moen, for example, lists Matte Black as a powder coat finish, its standard Brushed Nickel as a LifeShine PVD finish, and Spot Resist Brushed Nickel as a multi-step powder coat finish. Each gets different instructions.
| Brand and finish | Use | Avoid | For water spots |
|---|---|---|---|
| Moen Matte Black (powder coat) | Damp cloth and mild liquid dish soap, rinse, dry | Abrasives including abrasive sponges and steel wool, organic solvents like alcohols, lime scale removers | 50/50 vinegar and water for a limited time, then rinse and dry |
| Moen Brushed Nickel (LifeShine PVD) | Damp cloth and mild dish soap; Moen says most household cleaners, including mild abrasives, can be used as directed | Harsh cleansers like lime scale removers, green fibrous scrub pads | 0000 grade steel wool, or 50/50 vinegar and water, then rinse and dry |
| Moen Spot Resist Brushed Nickel | Damp cloth and mild dish soap, rinse, dry | Never abrasives or steel wool, ammonia, bleach, organic solvents, lime scale removers | 50/50 vinegar and water for a limited time, then rinse and dry |
| Delta (all finishes) | Damp non-abrasive sponge, then buff dry; Formula 409 Antibacterial, Fantastik or Windex Original if needed | Toilet bowl and industrial cleaners, green Scotch-Brite heavy duty sponges, tarnish and rust removers, hydrofluoric, hydrochloric or phosphoric acids, caustic agents | Warm water and a soft cloth; 50/50 white vinegar and water for hard water stains, rinsed well |
| Kohler (all faucet finishes) | Mild soap, warm water rinse, blot dry; for chrome or Vibrant finishes that get very dirty, Windex Original, Fantastik, Spic and Span Pine Liquid or Mr. Clean Springtime Fresh Scent | Abrasive cleansers, ammonia, bleach, acids | Kohler Assist describes a 50/50 vinegar and warm water wipe for mineral buildup |
| Pfister (all finishes) | Soft cloth with warm, soapy water | Polish, detergents, abrasive cleaners, organic solvents, acid products | 50/50 warm water and white vinegar on a soft cloth, per its support page |
| American Standard | Rinse with clear water, dry with a soft cotton cloth | Soaps, acids, polish, abrasives, harsh cleaners, coarse cloths | Check American Standard's instructions for your model |
Two notes on that table. First, the steel wool line for Moen's standard Brushed Nickel is Moen's own instruction for that PVD finish only. Don't carry it over to Spot Resist, matte black, or any other brand. Second, if you don't know which version you have, clean it as the most delicate one: soap, water, a quick vinegar wipe, and nothing abrasive.
### The vinegar question
Vinegar is an acid, and a few care pages seem to contradict each other on it. Kohler's printed maintenance guide says never to use cleaners containing acids, yet Kohler Assist describes a 50/50 vinegar solution for mineral buildup. Pfister's care page says to avoid "any product that has acid in it," while its troubleshooting page walks you through a 50/50 vinegar wipe for water spots. American Standard's page says never to use acids at all.
The way to square it: a diluted household vinegar wipe, rinsed off right away, is the method most of these brands describe for hard water spots. Strong acid cleaners and long soaks are a different story. Delta, for instance, names hydrofluoric, hydrochloric and phosphoric acids as things to avoid. If your brand's own page doesn't mention vinegar, call its support line before you use it.
### Matte black needs the lightest touch
Matte finishes show the most damage from scrubbing, because there's no gloss to hide a scuffed patch. On Moen's Matte Black, the avoid list includes abrasive sponges, steel wool, alcohols and lime scale removers. Wipe gently, rinse, and dry. If a spot survives two gentle vinegar rounds, stop and contact the manufacturer rather than reaching for something stronger.
Aerators, handles and other hard water trouble spots
The finish isn't the only thing hard water attacks. The small parts clog, too.
### Cleaning the aerator
The aerator is the screened tip on the end of the spout. When one faucet runs weak, a scaled aerator is often why. Pfister's support page gives this method:
- 1Unscrew the aerator by turning it counterclockwise.
- 2Submerge it in a 50/50 mix of warm water and white vinegar, just enough to cover it.
- 3Let it soak for approximately 60 minutes.
- 4Wipe off any remaining buildup on the aerator housing or spout tip with a soft cloth.
On a matte black or brushed nickel faucet, the aerator housing may carry the same finish as the spout. Protect it the same way: a cloth between the pliers and the finish if it's stuck, and a thorough rinse and dry after the soak. Our guide to low water flow from one faucet covers aerator cleaning in more detail, plus the shutoff valve check.
### Handles and bases
Scale builds up where water pools: around the base, under the handle and at the joint where the handle meets the body. Kohler Assist notes that faucet parts with heavy hard water buildup, like handles or aerators, can be hard to remove. The towel wrap described above loosens the scale first. If a handle has gotten stiff, see why a faucet handle is hard to turn. If the faucet drips, fixing a dripping faucet walks through the cartridge.
### Fewer spots in the first place
Drying the faucet after use is the simplest fix. The bigger one is softer water. Phoenix water is hard to very hard, and a whole-house water softener cuts the minerals that spot every finish in the house. The same minerals spot your shower glass; see how to remove hard water stains from glass shower doors.
How cleaning affects your faucet warranty
This is where the wrong cleaner costs you. Most major faucet brands warrant their finishes, but only with proper care.
### What the brands say
- Moen: Every finish section on its care page ends with the same line: "Failure to comply with these cleaning instructions may void Moen's warranty."
- Kohler: Its maintenance guide says: "Failure to comply with these cleaning instructions may void Kohler's warranty obligations."
- Pfister: It says that using polish, detergents, abrasive cleaners, organic solvents or acid products "will nullify your limited lifetime warranty and damage the finish." Its limited lifetime warranty covers the finish "with proper care."
- Delta: Its care page lists the cleaners and products that can damage your finish, so follow that list if you ever expect to file a claim.
### What that means for you
A finish that peels, bubbles or discolors on its own may be a warranty defect. A finish that scratches or dulls after a scouring pad or a lime scale remover is likely on you. Keep the receipt, register the faucet, and stick to the brand's cleaning rules. For the details of coverage, see whether Moen has a lifetime faucet warranty, whether Delta has a lifetime faucet warranty and American Standard's faucet warranty.
If a finish problem turns out to be a leak, a stuck handle or a faucet that needs replacing, a licensed plumber can sort out whether it's a warranty part or a repair. HQ Plumbing and Air is licensed and insured, gives upfront pricing and free estimates, and offers 24/7 emergency service.
