Keeping your stainless steel kitchen sink sparkling clean doesn’t just make your kitchen look fresh — it also helps preserve the sink’s quality and prevent damage over time. Stainless steel is known for its durability and resistance to rust, but it still requires proper care to maintain that sleek, modern finish. Whether your sink has a brushed or polished surface, learning the right cleaning techniques can make all the difference.

Below, we’ll break down the best ways to clean, maintain, and protect your stainless steel kitchen sink, with expert tips that every Aussie home can use.

So How to Clean a Stainless Steel Kitchen Sink?

1. Rinse and Wipe Daily

After each use, rinse your sink thoroughly with warm water to remove food particles, soap residue, and grease. Follow this with a soft microfibre cloth or sponge to dry the surface. This quick habit prevents water spots and keeps your stainless steel looking shiny.

If you’re using a stainless steel sink from Blue Leaf Bathware, a daily rinse and wipe-down will go a long way in maintaining its professional finish. These sinks are built for everyday use but still benefit from gentle daily care.

Tip: Always wipe in the direction of the grain to avoid micro-scratches that can dull the finish over time.

2. Use Mild Detergent and Baking Soda for Weekly Cleaning

Once a week, give your sink a more thorough clean. Use a few drops of mild dishwashing liquid mixed with warm water, and gently scrub using a soft sponge. For stubborn marks or greasy build-up, sprinkle some baking soda directly onto the wet surface and scrub lightly in the direction of the steel’s grain.

This helps lift grime without scratching the surface. Avoid harsh chemicals or abrasive pads that can dull the sink’s finish.

Tip: Mix baking soda and a few drops of lemon juice for a natural deodoriser that keeps your sink smelling fresh.

3. Remove Hard Water Stains with Vinegar

Australia’s tap water can often leave behind mineral deposits that cause dull spots. To tackle these, soak a clean cloth in white vinegar and lay it over the affected areas for about five minutes. Then, rinse thoroughly and wipe dry. The vinegar dissolves calcium build-up naturally — no need for harsh cleaning agents.

If your sink includes a sink grid or mat, make sure to clean it too. A dirty grid can transfer residue back onto your sink.

Tip: For extra shine, finish with a light buff of vinegar and water spray after cleaning. It helps prevent new water marks from forming.

4. Polish with Olive Oil or a Stainless Steel Cleaner

For that showroom-quality shine, apply a small amount of olive oil or a dedicated stainless steel cleaner to a soft cloth and buff in circular motions. This helps restore the original lustre while forming a light protective layer that repels water and fingerprints.

Pair your sink with a high-quality kitchen tap in brushed or polished steel to complete the look. Keeping both clean together will enhance your kitchen’s overall appeal.

Tip: Avoid using cooking oil that contains additives — stick to pure olive oil or mineral oil to prevent a sticky residue.

5. Keep the Drain and Waste Area Fresh

The drain area is often overlooked, but it’s where odours and grime tend to build up. Pour half a cup of baking soda followed by half a cup of white vinegar into the drain, wait 10 minutes, then rinse with boiling water. This natural cleaner helps clear minor blockages and leaves your sink smelling fresh.

If it’s time to upgrade or replace your existing waste fittings, explore sink wastes at Blue Leaf Bathware. Quality waste fittings not only look good but also prevent leaks and make cleaning easier.

Tip: Drop a few lemon peels into the drain after cleaning for a naturally fresh scent.

6. Protect the Surface from Scratches and Rust

Even stainless steel can scratch if you’re not careful. Avoid leaving cast iron pans, knives, or utensils sitting in the sink for long periods. Instead, use a sink mat or grid to protect the base from heavy cookware.

For kitchens with matching metallic finishes, pairing your sink with stainless steel tapware and accessories keeps the aesthetic consistent while ensuring durability.

Tip: Never use steel wool or abrasive pads — they can leave rust-prone particles on the sink’s surface.

7. Monthly Deep Clean Routine (for Extra Shine)

Every month, do a deep clean using this simple 3-step method:

Following this routine keeps your stainless steel sink spotless, smooth, and long-lasting — no need for expensive products.

Tip: Always dry your sink after deep cleaning to avoid mineral streaks, especially if you live in a hard-water area.

8. When to Replace or Upgrade Your Sink

Over time, even well-maintained sinks can show signs of wear. If you notice deep scratches, persistent discolouration, or leaks, it may be time to consider an upgrade. At Blue Leaf Bathware, you’ll find an impressive selection of kitchen sinks in premium stainless steel finishes, designed to suit both modern and traditional Australian kitchens.

Tip: When replacing your sink, choose one with sound-deadening pads or undercoating to minimise noise from running water and dishes.
