Quick answer: Most surface damage at home comes from using a cleaner that’s too strong for the finish, not from too little scrubbing. Find out what the surface is made of, start with warm water and mild dish soap on a soft cloth or sponge, test anything stronger on a hidden spot, rinse, and dry. Skip abrasive powders, steel wool, and stiff brushes unless your manufacturer allows them, and never mix bleach with vinegar, ammonia, or other cleaners.
Faucets, tubs, shower floors, and stainless appliances look tough, but their finishes are thin. A powder coat on a faucet, the gelcoat on a fiberglass tub, the clear coat on a fridge door: once you scratch or dull them, cleaning won’t bring them back. This surface cleaning guide collects the rules that show up again and again in manufacturer care instructions, then points you to our detailed, step-by-step guides for each surface.

Six rules that protect almost every finish
1. Know the material before you pick a cleaner
“Stainless,” “fiberglass,” and “matte black” each cover several different finishes, and the care rules change between them. Whirlpool, for example, lists different methods for traditional stainless, fingerprint-resistant stainless, and black stainless. Check the owner’s manual, a label on the product, or the maker’s website. If you can’t tell, treat the surface as delicate and stick to soap and water.
2. Start with the mildest method
Mild dish soap and water is the first step in nearly every care guide we used. Moen says a damp cloth and mild liquid dishwashing soap can be used, followed by rinsing with water and drying with a soft cloth. Whirlpool says to wash traditional stainless with warm, soapy water and a nonabrasive sponge. MAAX recommends a non-abrasive cleaning spray, a cream-based cleanser, or dish soap for its tubs and showers. Only move to something stronger when the gentle step clearly isn’t working.
3. Test first, on a spot no one sees
Makers repeat this one for a reason. Mr. Clean tells you to test a small area with light pressure before using its Magic Eraser, and MAAX says to read a product’s directions closely and test on a small surface if needed. A test spot takes a minute. A dull streak across a tub wall can be permanent.
4. Keep abrasives away unless the maker approves them
Abrasive powders, steel wool, wire brushes, and green scrub pads are the most common way finishes get scratched. GE Appliances says not to use steel wool, abrasives, ammonia, acids, or bleach on stainless and warns that a green scrub pad can scratch it. KOHLER says not to use steel wool, wire brushes, or abrasive sponge pads on its cast iron shower bases, and MAAX says never to use abrasive cleansers, scrapers, or metal brushes on its tubs and showers. Brushes are where makers disagree most: Aquatic allows a brush on its textured floors as long as it’s no rougher than a toothbrush, while KOHLER’s care page for some bases says not to use a brush at all. Follow your own brand’s rule.
5. Treat acids and bleach as “check first” products
Vinegar is a common go-to, but it isn’t safe everywhere. Moen allows a 50/50 vinegar and water mix on its faucet finishes, followed by rinsing and drying. Pfister says to avoid any product that has acid in it, and Whirlpool says not to use vinegar-based or citrus-based cleaners on its stainless finishes. Bleach has limits too. The University of Georgia Extension warns that chlorine bleach will set rust stains instead of removing them.
6. Never mix cleaners, and rinse well
Poison Control warns that mixing bleach with ammonia or with an acid can create dangerous gases, and vinegar is an acid. The CDC says never to mix household bleach with other cleaners and to keep the room well ventilated. Rinse one product off completely before you try another. Rinsing matters for safety on floors as well: on slip-resistant shower floors, residue left behind can make the surface slick, which is why our shower floor guide covers rinsing in detail.
What you need for most surfaces
- Mild liquid dish soap and warm water
- Soft cloths or microfiber cloths for washing and drying
- A nonabrasive sponge
- A soft nylon brush (only for surfaces where your maker allows a brush)
- Distilled white vinegar, for hard water on finishes that allow it
- Rubber gloves, and a fan or open window when you use anything stronger than soap
A simple routine that prevents most stubborn buildup
- After use: Rinse and wipe wet surfaces dry. KOHLER suggests rinsing thoroughly and wiping dry after each use on its cast iron shower bases. Drying keeps water spots and soap film from building up on faucets and tubs too.
- Weekly: Wash with mild soap and water, rinse, and dry. Wipe stainless in the direction of the grain.
- As needed: Use your maker’s approved product for hard water, rust, or mildew, one product at a time, then rinse.
- Before anything new: Read the label and test a hidden spot.
When a surface needs more than cleaning
Some damage can’t be cleaned away. If a finish is scratched, peeling, or dull after the wrong product, stop scrubbing. More effort usually spreads the damage. Contact the manufacturer. Pfister, for example, says using the wrong products can nullify its finish warranty and damage the finish. GE Appliances says scratches on its CleanSteel finish, a vinyl laminate made to look like stainless, can’t be repaired and the part would need to be replaced. Rust that keeps coming back in a tub or sink often points to iron in the water, which our rust stain guide explains.
For sink-area quartz, see our hard water stains on quartz countertops guide. Confirm the countertop brand and finish; a faucet’s vinegar permission does not apply to adjacent quartz.
FAQ
What is the safest all-purpose way to clean household surfaces?
Warm water with a little mild dish soap, a soft cloth or nonabrasive sponge, a clean-water rinse, and a dry towel. Most manufacturer care guides start here, including Moen, Whirlpool, and MAAX.
Is vinegar safe on faucets and stainless steel?
It depends on the brand. Moen allows a 50/50 vinegar and water mix on its faucet finishes, but Pfister says to avoid acids, and Whirlpool says not to use vinegar-based cleaners on its stainless finishes. Check your product’s care page before you use it.
Can I use a Magic Eraser on bathroom and kitchen surfaces?
Be careful. Mr. Clean lists high gloss, polished, dark, brushed, satin, and stainless steel appliance surfaces as not recommended, and MAAX lists cleaning erasers among the things not to use on its Utile wall panels. Our Magic Eraser on stainless steel guide covers this in detail.
How do I clean grooves in a textured shower floor without a stiff brush?
Let a nonabrasive cleaner sit for a few minutes so it does the work, then use only the tool your maker allows. See our textured shower floor guide for each material.
