How to Clean and Polish Your Exhaust Tips Like a Pro

Those swirl marks you see in sunlight? That's years of improper washing ground into your paint. But they're fixable.

Dull, blackened exhaust tips can ruin the look of an otherwise spotless car. Here is how to strip back the carbon soot and road grime to get that mirror finish back on your chrome or stainless steel.

How to Clean and Polish Your Exhaust Tips Like a Pro

Aussie Conditions

Australian conditions are tougher than most—intense UV, red dust, coastal salt, and 40°C summers. European car care advice often doesn't cut it here.
Quick Summary

Look, there is no point spending four hours washing and waxing your car if the exhaust looks like it has been dragged through a coal mine. This guide is for anyone from the weekend warrior with a shiny daily driver to the bloke with a big diesel rig that's seen a bit too much red dust. I'll walk you through the gear you actually need and the technique to get it done properly without scratching your metal to bits. It is a bit of a grubby job, but the results are always worth it.

01

Why Bother with the Exhaust?

Right, let's be honest. Most people forget about their exhaust tips until they're so caked in black soot they look like they've been painted matte black. After 15 years in the detailing game, I've seen some absolute shockers. I once had a customer bring in a beautiful white Audi RS6 where the tips were so black you couldn't tell they were originally chrome. The bloke thought he needed a whole new cat-back system! In Australia, we've got it tough. If you're near the coast, that salt spray reacts with the heat of the exhaust and starts pitting the metal faster than you'd believe. Or if you've been out bush, that fine red dust bakes onto the hot metal like ceramic. Honestly, leaving that muck on there doesn't just look bad, it actually eats into the finish. Taking 20 minutes to sort it out every few months makes a world of difference. Your car just doesn't look 'finished' until the metal is popping.
02

The Gear You'll Actually Use

What You'll Need

0/8
Wheel cleaner or a good APC — Something like Bowden's Own Wheely Clean works a treat for breaking down initial soot.
0000 Grade Steel Wool — Must be 'four-zero' grade. Anything coarser will scratch the living daylights out of your chrome.
Metal Polish — Autoglym Metal Polish or Meguiar's NXT Generation All Metal Polish are my go-to's.
Dedicated Microfibre Towels — Use old ones you're happy to throw away. They will get filthy black.
Small Soft Brush — An old toothbrush or a detailing brush to get into the gaps.
Gloves — Nitril gloves are a must. Carbon soot is a nightmare to get out from under your fingernails.
A Bucket of Water — Just for rinsing. No need to get fancy here.
Safety Glasses — Especially if you're lying on the ground looking up at the pipes.

Pro Tip: The Steel Wool Secret

A lot of guys are terrified of steel wool. Look, I get it. But 0000 grade is so fine it's basically like a heavy-duty fabric. I learned this the hard way on a black Commodore years ago, tried to use a kitchen scourer and ruined the tips. Never again. Stick to the 0000 and always use it with a lubricant like a bit of quick detailer or even soapy water.

Preparation is Key

Tap each step to mark complete
01

Wait for it to cool down

Don't be a hero. I've seen more than one mate try to clean his tips at the servo after a long run and end up with no skin on his knuckles. Give it at least an hour.

02

Rinse off the loose grit

Give it a good blast with the hose. This gets rid of the sand and dust that'll cause deep scratches once you start scrubbing.

03

Degrease

Spray your wheel cleaner or APC onto the tips and let it dwell for 2-3 minutes. Don't let it dry in the sun though, standard Aussie rules.

04

The Dirty Work: Step-by-Step

Tap each step to mark complete
01

Initial Scour

After your degreaser has done its thing, use your brush to agitate the soot. Rinse it off and see what you're dealing with. Usually, the bottom of the tip is the worst.

02

The Lubricated Scrub

Grab a small piece of that 0000 steel wool. Spray a bit of soapy water on the tip and start gently rubbing the metal. Don't push too hard, let the wool do the work.

03

Focus on the Edges

The very edge of the exhaust pipe usually has the thickest carbon build-up. Spend a bit more time here. If it's really stuck, you might need a bit more elbow grease.

04

Wipe and Inspect

Wipe the slurry away with a damp cloth. You're looking for any remaining black spots or 'pitting' (tiny little holes in the metal).

05

Apply Metal Polish

Chuck a dollop of metal polish onto a microfibre applicator or an old rag. Spread it evenly over the whole tip.

06

Work the Polish

Rub the polish in using firm, circular motions. You'll notice the polish starts turning black, that's a good sign! It means it's reacting with the oxidation and pulling it off.

07

The 'Shoeshine' Technique

For round tips, I reckon the best way is to wrap a long strip of cloth around the pipe and pull it back and forth like you're shining a pair of boots. This gets the underside where you can't see.

08

Final Buff

Use a clean section of your microfibre to buff the residue off. You should be seeing your face in the reflection now.

09

Don't Forget the Inside

Most people only clean the outside. I usually go about 2-3cm into the inside of the pipe as well. It makes the whole thing look much more professional.

Watch Out

If your exhaust tips are matte black or powder-coated from the factory (common on modern performance cars), DO NOT use metal polish or steel wool on them. You'll strip the coating right off and end up with a patchy mess. For those, just use soap, water, and maybe a bit of spray wax.

Dealing with Pitting

If you've got those tiny little black rust spots that won't come off, that's pitting. It's common in coastal areas like the Gold Coast or Perth. You can't really 'clean' them off as they are holes in the metal. The best you can do is polish them well and keep them sealed to stop them getting worse.
05

Keeping it Shiny

Now that you've put in the hard yards, you don't want to be doing this every weekend. The trick is to seal the metal. I usually chuck a bit of ceramic sealant or even a high-temp wax on the tips after polishing. It makes the soot sit on top rather than bonding to the metal. Next time you wash the car, just wipe the tips with your leftover soapy water from the bucket. Honestly, if you do that every wash, you'll only need to do the full polish once or twice a year. If you've just come back from a trip out to the Red Centre or a beach run, make sure you hose the tips out properly to get the salt and dust out of the crevices. Your future self will thank you.

Common Questions I Get Asked

Can I use WD-40 to clean my exhaust?
You can use it to loosen some grease, but I wouldn't bother. It doesn't have the abrasives needed to polish the metal. Stick to a proper metal polish for the best result.
My tips are yellowed, what is that?
That's usually heat discolouration. Most good metal polishes will take some of it out, but on stainless steel, it's often permanent. Some blokes like the 'gold' look, others hate it. Personally, I reckon it shows the car actually gets driven!
Will this work on my motorbike exhaust?
Yeah, absolutely. Just be extra careful around chrome-plated heat shields as they can be a bit thinner than car exhaust tips.
Is it okay to use a drill with a polishing pad?
If you've got the room, go for it! It'll save your arms. Just watch the speed, if you get it too hot, you can actually burn the finish.
