Stainless steel is a staple material across Australian homes and commercial environments — from kitchen benchtops and splashbacks to outdoor BBQ areas and industrial workstations. Its durability, corrosion resistance, and sleek appearance make it a popular choice, but without proper care it can quickly lose its shine.
If you’re looking for the best way of polishing stainless steel, this guide covers everything you need to know. Whether you’re maintaining a stainless steel bench in a commercial kitchen or restoring the shine of your home appliances, these practical tips will help you achieve a professional, streak-free finish.
What Is Stainless Steel Polishing?
Stainless steel polishing is the process of restoring or enhancing the surface finish of stainless steel to improve its appearance and performance. While many people confuse cleaning with polishing, they serve different purposes:
- Cleaning removes dirt, grease, and contaminants
- Polishing restores shine and smoothness
- Finishing refers to the surface texture (e.g., brushed, satin, mirror)
Polishing stainless steel not only improves its visual appeal but also helps maintain the protective chromium layer that prevents rust and corrosion.
How to Polish Stainless Steel
Follow this proven method to achieve a clean, polished, and streak-free finish.
1. Using Vinegar
There are different types of vinegar and it is recommended to choose cider vinegar, as it will leave a more pleasant scent on the surface. If there are stains on the surface or there is heavy tarnishing, use cleaning vinegar.
Use the following steps when polishing stainless steel surfaces:
- Check the grain’s direction
- Use a spray bottle to spray the vinegar on the steel surface to create a thin coat
- You may also moisten a soft cloth with vinegar as an alternative
- Dilute the vinegar (1/2 cup against 1 quart of warm water) for light polishing
- Use undiluted vinegar if there is heavy staining
- Wipe the surface along the direction of the grain to reach the grooves where grime, dust, and dirt gets trapped
It is important that no vinegar stays in the grooves, as it can cause the steel to fade after some time. Use a soft cloth instead of paper towels — they won’t leave fibres behind.
2. Using Specialised Cleaners
There are specialised cleaners available for achieving optimal results with your stainless steel polishing needs. Choose a non-wax-based polish with mild abrasive properties, then decide whether you need a water-based or oil-based cleaner.
Water-Based Cleaners
These cleaners are less toxic and environmentally friendly, but they are not ideal at removing fingerprints or smudges.
Oil-Based Cleaners
Oil-based cleaners provide better polishing results and leave a light protective layer that repels future fingerprints.
Steps to polish using specialised products:
- Choose a properly ventilated area for the task
- Wear a pair of rubber gloves
- Spray the cleaner over the item using the directions on the label
- Use a dry microfibre cloth to wipe the surface in the direction of the grain
3. Using Olive Oil
Take a soft cloth and flip an open bottle of olive oil over it. Let the oil soak into the cloth for a couple of seconds. Then follow these steps:
- Use the soaked cloth to coat the stainless steel surface in the oil
- Use circular motions with slight pressure
- Continue the process for a few minutes until the entire surface is covered
- Wipe the surface until a light sheen forms
- Make sure the polishing is even
- Use a paper towel or clean cloth to remove any excess olive oil
Keep wiping until the surface no longer feels oily. You may also use baby oil or liquid paraffin for the same purpose.
For tough tarnishing, consider using lemon juice. It has acidic properties that are highly effective at removing tarnish without harsh chemicals.
Polishing Stainless Steel Benches and Commercial Kitchen Surfaces
Commercial kitchen benches and workstations take significantly more punishment than home surfaces. High heat, grease, food acids, and constant use can dull the finish fast. Here’s what works specifically for commercial stainless steel kitchen environments:
- Use a food-safe oil-based polish. Products like Bar Keepers Friend or Autosol are food-safe and approved for commercial kitchen use. Apply weekly on high-contact surfaces.
- Polish after every deep clean. Commercial kitchens should be polished after each weekly chemical clean to restore the protective surface layer that daily sanitisers strip away.
- Always work with the grain. On fabricated benches, the brushed grain runs lengthways. Polishing against it leaves visible hairline scratches that become breeding grounds for bacteria.
- For welded joins and edges, use a cotton tip or narrow cloth to work polish into the seams — these are the areas most prone to pitting and corrosion.
If you’re operating a commercial kitchen in Brisbane or South East Queensland and your benches are looking dull, scratched, or pitted, it may be worth considering a professional-grade custom stainless steel bench replacement rather than continuing to polish a surface past its useful life.
Best Products for Polishing Stainless Steel in Australia
Here is a practical comparison of the most commonly available stainless steel polishes in Australia, based on surface type and application:

DIY solutions like vinegar and baking soda are effective for light cleaning, but commercial-grade polishes are better suited for heavy-duty or professional environments.
How Often Should You Polish Stainless Steel?
The frequency of polishing depends on how the surface is used:
- Residential kitchens: Every 1-2 weeks
- Commercial kitchens: Weekly or even daily for high-use areas
- Outdoor stainless steel (BBQs, benches): More frequently due to exposure to weather and coastal conditions
In Australia, outdoor stainless steel surfaces may require extra attention due to UV exposure, humidity, and salt air — particularly in coastal areas like the Sunshine Coast and Gold Coast.
Maintaining Stainless Steel After Polishing
After successfully polishing stainless steel, proper maintenance will keep it looking its best for longer.
Daily Maintenance Tips
- Wipe surfaces with a damp microfibre cloth
- Dry immediately to prevent water spots
- Clean spills promptly
Preventing Fingerprints and Smudges
- Use a light coat of oil to reduce marks
- Avoid touching surfaces with greasy hands
Routine Care Checklist
- Weekly wipe-down with diluted vinegar solution
- Monthly polish for high-traffic areas
- Inspect for scratches or wear
Consistent maintenance reduces the need for intensive polishing in the future.
Common Mistakes to Avoid When Polishing Stainless Steel
Even with the right tools, mistakes can lead to damage or poor results. Avoid the following:
- Polishing against the grain – Causes visible scratches
- Using steel wool or abrasive pads – Permanently damages the surface
- Applying bleach or harsh chemicals – Can corrode stainless steel
- Skipping the cleaning step – Traps dirt and leads to streaks
- Overusing water – Leaves marks and residue
- Polishing scratched surfaces without treating first – Use a scratch removal method before polishing
What Are the Benefits of Polishing Stainless Steel?
- Enhanced aesthetics – Restores a mirror-like or brushed finish that looks professional and clean
- Corrosion resistance – Polishing removes microscopic surface contaminants that allow rust to take hold
- Hygienic properties – Smoother surfaces have fewer pores, making them easier to sanitise in food environments
- Durability and longevity – Regular polishing reduces surface wear and extends the life of the steel
- Chemical resistance – A polished surface repels chemical attacks better than a rough or dull finish
Frequently Asked Questions About Polishing Stainless Steel
Can you use WD-40 to polish stainless steel?
Yes, WD-40 can be used as a short-term fix to restore shine and repel fingerprints on stainless steel surfaces. Spray a small amount onto a soft cloth and wipe in the direction of the grain. However, it is not food-safe and should not be used on food-contact surfaces like kitchen benchtops. For commercial kitchens, use a food-safe stainless steel polish instead.
Does vinegar damage stainless steel?
Diluted vinegar is safe for stainless steel when used correctly and rinsed off promptly. Undiluted vinegar left sitting in grooves or seams for extended periods can cause surface dulling over time. Always wipe off vinegar thoroughly after polishing and dry the surface immediately.
What is the best polish for stainless steel benches in a commercial kitchen?
For commercial kitchen benches, Bar Keepers Friend is widely regarded as the best option in Australia. It is food-safe (when rinsed off), effective at removing heavy staining and tarnish, and available at most Bunnings stores. For regular maintenance between deep cleans, a food-safe oil-based spray polish applied with a microfibre cloth is ideal.
How do you get scratches out of stainless steel before polishing?
Light scratches can often be buffed out using a fine-grade stainless steel scratch removal pad or a small amount of Bar Keepers Friend applied with a cloth in the direction of the grain. Deep scratches may require professional refinishing. Always treat scratches before polishing — applying polish over deep scratches will not hide them and can make them more visible.
How do you polish a mirror finish on stainless steel?
Mirror-polished stainless steel requires a different approach to brushed finishes. Use a dedicated metal polish like Autosol or Brasso applied with a clean cotton cloth. Work in small circular sections, then buff off with a clean dry cloth. Avoid abrasive products that will scratch the reflective surface. Mirror finishes show fingerprints more easily, so a regular light wipe with a microfibre cloth is essential maintenance.
Can baking soda be used to polish stainless steel?
Yes. A paste made from baking soda and water is a gentle DIY option for light polishing and stain removal. Apply the paste with a soft cloth in the direction of the grain, leave for a few minutes, then wipe off and rinse. It is particularly useful for removing water stains and light discolouration from sinks and home appliances.
Is stainless steel polishing the same as stainless steel cleaning?
No. Cleaning removes surface dirt, grease, and contaminants. Polishing restores the surface finish, removes micro-scratches and oxidation, and adds a protective layer. You should always clean a surface first before polishing — polishing over a dirty surface traps contaminants and leads to streaking.
