So, you’ve got some stainless steel surfaces at home that need a little love and attention, and you’re wondering if you can use Comet, the classic cleaning powder, on them?

The short answer? Yes, you CAN use Comet on stainless steel. 

It’s pretty good at cutting through grime, grease, and stubborn stains. But you have to be cautious.

In this post, I’ll show you how to use Comet on stainless steel in detail.

Is It Safe To Use Comet On Stainless Steel?

Yes, it's safe to use Comet on stainless steel.

Stainless steel is pretty tough, but it’s still important to be gentle. Comet’s abrasive texture can clean up stains and grime, but if you’re too rough or don’t rinse it off properly, it could leave marks

One thing to keep in mind is that Comet might not be the best choice for high-end or delicate stainless steel appliances, like the ones you’d find in luxury kitchens.

If you’ve got one of those, it might be a good idea to do a test run first or use a gentler cleaner that’s designed specifically for stainless steel.

But for most everyday appliances like sinks, refrigerators, and stovetops, Comet should do the trick without causing harm.

How To Clean Stainless Steel With Comet

Now for the fun part - actually cleaning! Here’s a step-by-step guide to using Comet on stainless steel without causing any damage:

#1 Test First

Before you jump into cleaning your entire stainless steel surface, do yourself a favor and test Comet on a small, hidden spot. 

Why? Because every piece of stainless steel is slightly different. Some might have a super polished finish, while others are brushed or textured. 

A quick test ensures you won’t accidentally ruin the whole thing.

To test, sprinkle just a tiny bit of Comet onto the area. Grab a soft sponge or cloth and gently rub it in. Don’t press too hard—just a light touch will do. After a minute or so, rinse the spot with water and dry it off. Take a close look. 

Does it still look shiny and smooth? Great! You’re good to go. 

If you notice any dulling or scratching, it’s probably best to skip Comet for this particular surface.

#2 Create A Paste (Optional)

If you’re dealing with a really stubborn stain—like those mysterious brown spots on your sink or baked-on grease on your stovetop—you might want to make a paste out of Comet. 

This step is totally optional, but it can make your life easier.

Here’s how to do it: grab a small bowl and add a spoonful of Comet powder. Slowly mix in a few drops of water until you get a thick, toothpaste-like consistency. 

The paste sticks better to vertical surfaces, like the sides of your fridge or the front of your oven. 

Plus, it gives the product more time to break down tough grime.

#3 Apply Comet

Once you’ve tested and maybe made a paste, it’s time to apply Comet to the area you want to clean. 

If you’re using the powder, sprinkle it lightly over the surface. There’s no need to dump half the container—less is more. For paste, scoop a small amount onto the area and spread it around with your fingers or a sponge.

Be mindful of how much you’re using. Overdoing it can make rinsing harder later. And honestly, Comet is powerful stuff. A little sprinkle or dab is usually enough to tackle most messes. 

Focus on the stained or dirty areas rather than covering the entire surface. 

This way, you save product and avoid unnecessary scrubbing.

#4 Gently Scrub

Once you’ve got the Comet on the surface, it’s time to scrub.

Grab a soft sponge, cloth, or even an old T-shirt. Avoid anything too abrasive, like steel wool or a rough scrub brush. Even though Comet has mild abrasives, adding extra friction with a harsh tool can lead to scratches.

Use gentle, circular motions to scrub the area. 

If you’re cleaning something large, like a sink, focus on one section at a time. This makes the job feel less overwhelming and ensures you don’t miss any spots. 

For tougher stains, let the Comet sit for a minute or two before scrubbing. This gives it time to break down the grime.

Take your time here. Rushing through the process can lead to uneven cleaning or accidental damage.

#5 Rinse And Wipe

After you’ve scrubbed away the grime, it’s time to rinse everything off. 

Grab a damp cloth or sponge and wipe down the area thoroughly. Make sure all the Comet is gone. Leaving residue behind can leave a dull film or attract more dirt later.

If you notice streaks or spots, give the area another quick rinse. Sometimes it takes a second pass to get everything sparkling clean. 

Pay special attention to corners or crevices where Comet might hide. These spots can be easy to overlook but are prime areas for leftover residue.

Once you’ve rinsed, take a step back and admire your work. Your stainless steel should already be looking better, but we’re not done yet. One last step remains.

#6 Drying

The final step—and arguably the most important—is drying. 

Stainless steel can show water spots if left to air dry, and it can ruin the shine.

So grab a clean, soft towel and dry the surface completely.

If you’re cleaning something like a sink, pay extra attention to the edges and handles. These areas tend to collect water droplets. For larger surfaces, like a fridge or oven, work in sections to ensure you don’t miss any spots. 

A microfiber cloth works great here because it absorbs water quickly and leaves a streak-free shine.

Bottom Line

In the end, yes, Comet can be used on stainless steel, but with a little care and attention. 

It's a fantastic cleaner for most stainless steel appliances, but it’s important to follow the steps to avoid damaging the finish. Always test first, use a gentle hand, and remember to rinse and dry.

So, next time you’re facing greasy fingerprints or stubborn stains on your stainless steel, don’t be afraid to reach for the Comet!
