Plumber’s putty is commonly used to create watertight seals around sink drains and faucets. However, during installation or repair, excess putty can squeeze out and harden, leaving greasy residue or dull marks on your stainless steel sink. Removing it correctly is important to avoid scratches or discoloration on the steel surface.
Plumber’s putty is an oil-based sealing compound. It doesn’t chemically bond to metal but can leave behind an oily film. The goal is to remove the residue mechanically (by lifting it off) without scratching the stainless steel, then clean the surface of leftover oils.
Plastic scraper or old credit card
Soft cloth or microfiber towel
Warm water
Mild dish soap
White vinegar or rubbing alcohol
Baking soda (optional for deeper cleaning)
Rubber gloves
Avoid steel wool, metal blades, or abrasive pads — they can permanently scratch the sink’s finish.
If the putty has hardened, you need to soften it first for easy removal.
Place a hot, damp cloth over the putty area for 10–15 minutes.
Alternatively, use a hair dryer on low heat for a few minutes to gently warm the putty.
Once softened, it should feel pliable and easier to scrape.
Do not use boiling water or high heat — it may warp caulking or affect the sink’s sealant.
Use a plastic scraper, rubber spatula, or the edge of an old credit card.
Work slowly to lift the putty without digging into the steel surface.
For narrow areas (like around the drain), use a soft cloth wrapped around your fingertip.
Always scrape along the direction of the stainless steel grain, not against it.
After scraping, you’ll likely notice a greasy film or dull spot left behind.
Mix a few drops of mild dish soap with warm water.
Dip a soft cloth in the soapy solution and wipe the area thoroughly.
Rinse with clean water.
If residue remains:
Apply white vinegar or rubbing alcohol to a clean cloth.
Rub gently until the surface feels smooth and oil-free.
Vinegar helps break down any remaining oily film and restores the steel’s natural sheen.
If you still see residue or discoloration:
Sprinkle a little baking soda onto the area.
Spray with vinegar to create a mild fizz.
Gently rub using a damp microfiber cloth.
Rinse and dry completely.
This combination lifts light stains without scratching.
Rinse thoroughly with warm water to remove any cleaner residue.
Wipe completely dry using a microfiber towel to prevent new water spots.
Always dry stainless steel after cleaning — standing water can cause mineral deposits or streaks.
When applying new plumber’s putty, use only a thin, even bead around the fixture.
Immediately wipe away excess before it hardens.
For stainless steel sinks like Shunhan’s, consider using non-oil-based sealants (like silicone) for easier cleanup.
Clean and dry the sink regularly to prevent residue buildup.
After removing the putty and residue, restore your sink’s brilliance by polishing:
Apply a few drops of mineral oil or stainless steel cleaner on a microfiber cloth.
Buff gently along the grain.
Wipe off any excess with a dry towel.
This adds a protective layer and enhances the reflective finish.
