Getting Your Exhaust Tips Back to a Mirror Finish

Your paint is under constant attack: UV rays, bird droppings, tree sap, and road grime. Protection isn't optional—it's essential.

Burnt-on carbon and road grime can make even the best looking car look like a local tip find. I'll show you how to cut through the crust and get those pipes shining like new again.

Getting Your Exhaust Tips Back to a Mirror Finish

Aussie Conditions

Our intense UV breaks down waxes faster than overseas. Ceramic coatings last longer, but even they need topped up more frequently here.
Quick Summary

Look, nobody likes a grubby rear end. Whether you're rocking a dual-exit on a V8 Commodore or just want your daily driver looking sharp, cleaning your exhaust tips is one of those small jobs that makes a massive difference. In this guide, I'm going to walk you through the exact methods I've used for over 15 years to restore everything from soot-covered diesels to high-end titanium tips.

01

The Lowdown on Exhaust Care

Right, let's be honest. Most people ignore their exhaust tips until they're so black you'd think they were painted matte. I see it all the time with my mobile detailing business, a bloke brings in a beautiful car, paint's gleaming, interior's mint, but the exhaust looks like it's been pulled out of a bonfire. It really lets the whole look down. Thing is, leaving that carbon soot and road salt on there isn't just an eyesore; it actually pits the metal over time. Once that rust starts eating into the chrome or stainless, you're pretty much stuffed and looking at a replacement. I learned this the hard way years ago on my first decent car, a black VR Commodore. I thought 'she'll be right' and let the soot build up for months. By the time I tried to clean it, the heat had basically baked the carbon into the metal. I spent about four hours scrubbing and barely made a dent. Since then, I've refined the process to be way more efficient. In Australia, we've got it pretty tough. If you're living near the coast, that salt air reacts with the heat of the exhaust and speeds up corrosion like nobody's business. Then you've got the red dust if you've been out west, which gets into the microscopic scratches and stays there. And don't even get me started on the heat. March in Australia is still bloody hot, and that ambient temperature plus the 300-odd degrees of your exhaust pipe makes for a very stubborn mess. But don't stress, I've got a system that works, and I'll walk you through it so you don't end up with sore arms and a half-baked result.

What You'll Need in Your Kit

What You'll Need

0/13
Wheel Cleaner or Heavy Duty Degreaser — I reckon Bowden’s Own Wheely Clean is a cracker for this. The iron fallout remover in it helps break down the metal particles.
Metal Polish — Autoglym Metal Polish or Meguiar's NXT Generation All Metal Polish are my go-tos. Don't waste your money on cheap supermarket stuff.
0000 Grade Steel Wool — Crucial: It must be 'four-zero' grade. Anything coarser will scratch the living daylights out of your tips.
Microfibre Cloths — Chuck away the ones the missus uses for dusting. Get some decent 300GSM cloths you don't mind ruining.
Soft Bristle Detail Brush — For getting into the gaps between the tip and the bumper.
Nitrile Gloves — Carbon soot is a nightmare to get out from under your fingernails. Trust me on this one.
Multi-Purpose Cleaner (APC) — Something like Koch Chemie Green Star, diluted 1:10 for the initial wash.
Wheel Woolie or Bottle Brush — Essential for cleaning the inside of the pipe where your hand won't fit.
High-Pressure Washer — Or a decent hose with a jet nozzle to blast away the loose grit.
Masking Tape — To protect the plastic bumper or diffuser. I use the blue 3M stuff.
Metal Sealant or Ceramic Coating — Gtechniq C5 Wheel Armour works wonders on exhaust tips to stop soot sticking next time.
A Kneeling Pad — Your knees aren't as young as they used to be (or mine aren't, anyway).
Bucket of soapy water — Just your standard car wash shampoo is fine here.

Watch Out

This sounds like common sense, but you'd be surprised how many blokes try to clean their tips right after a long drive. Those pipes can stay hot enough to blister your skin for a good 30 minutes after the engine's off. Give it an hour. If you can't hold your hand on it comfortably, don't touch it with chemicals or steel wool.

Getting Ready for the Scrub

Tap each step to mark complete
01

Park in the Shade

Never work on a hot exhaust in the direct Aussie sun. The chemicals will dry instantly and leave nasty streaks.

02

Mask Up the Plastic

Tape off the area around the exhaust. If you get metal polish on textured black plastic trim, it's a mongrel to get off.

03

Initial Blast

Hit the tips with a high-pressure hose to get rid of any loose dirt, sand, or salt spray. This prevents you from grinding grit into the finish.

04

Apply Degreaser

Spray your APC or degreaser heavily inside and outside the tip. Let it dwell for 2-3 minutes, but don't let it dry.

05

Agitate the Grime

Use your detail brush to work the degreaser into the soot. You'll see the brown/black sludge start to run.

06

Rinse Thoroughly

Blast it all off. You want a clean (though probably still stained) surface before you start polishing.

The Step-by-Step Polishing Process

Tap each step to mark complete
01

Dry the Surface

Use an old microfibre to dry the tips completely. Water acts as a lubricant we don't want yet.

02

Assess the Damage

Look for pitting or heavy carbon build-up. If it's just lightly hazy, you can skip the steel wool.

03

Apply Polish to Steel Wool

Take a small clump of 0000 steel wool and dab a decent amount of metal polish onto it. Don't use the wool dry.

04

Scrub the Inner Edge

Start with the 'rolled' edge and the inside of the tip. This usually has the thickest carbon. Use firm, circular motions.

05

Work the Outer Surface

Move to the visible outside parts. Go easier here; you want to clean, not grind.

06

Check Your Progress

Wipe a small section with a clean cloth to see if the stains are lifting. If not, keep at it with the wool.

07

Switch to Microfibre

Once the heavy crust is gone, grab a fresh microfibre cloth and apply a fresh pea-sized drop of polish.

08

High-Speed Rubbing

Rub the polish in briskly. The friction and heat help the chemical cleaners in the polish work their magic.

09

The Shoe-Shine Technique

For round tips, wrap the cloth around the pipe, hold both ends, and pull back and forth rapidly like you're shining shoes.

10

Wait for the Haze

Let the polish sit for about a minute until it turns into a light, chalky haze.

11

Buff to a Shine

Use a clean section of the microfibre to buff off the residue. This is the satisfying part where the shine pops.

12

Clean the Hard-to-Reach Bits

Use a cotton bud or the edge of your brush to get any polish residue out of the lettering or logos stamped on the tip.

13

Final De-grease

Wipe the whole thing down with a bit of Isopropyl Alcohol (IPA) or a panel wipe to remove any oily polish residue.

14

Apply Protection

Apply your ceramic coating or high-temp sealant. This makes the next wash ten times easier.

15

Buff Protection

Follow the product instructions, usually buffing off after 30 seconds to a minute.

16

Remove the Tape

Peel off your masking tape and give the bumper a final wipe down.

The Drill Hack

If your tips are absolutely cactus and you've got a lot of surface area, don't kill your arms. Get a cone-shaped foam polishing tool that attaches to your cordless drill. Stick some polish on that and let the tool do the work. Just watch your speed, too fast and you'll sling black polish all over your driveway.

Watch Out

Some blokes reckon using wheel acid is a great shortcut. Honestly, I wouldn't bother unless you really know what you're doing. If you leave an acidic cleaner on chrome for too long, it can cause 'milking' or permanent staining that you'll never polish out.
05

Next Level: Sanding and Titanium

Alright, so you've tried the polish and it's still looking pitted? You might need to move to wet-sanding. I've had to do this on a few old Maloo utes that have seen a lot of red dirt. You start with 1500 grit wet-and-dry sandpaper, soaked in soapy water, and sand back the pitting. Then move to 2000, then 3000, then back to the metal polish. It's a mission, but it'll save a 'dead' exhaust. Also, a quick word on Titanium tips (the ones with the blue burnt look). **Do not use steel wool or abrasive polishes on these!** You'll rub that blue finish right off and you'll be left with a very expensive, very plain looking pipe. For titanium, stick to a very light non-abrasive metal cleaner and a soft cloth.

Check the Material

Not all 'shiny' exhausts are the same. A quick trick: put a magnet on it. If it sticks strongly, it's likely chrome-plated steel. If it doesn't stick or the pull is very weak, it's high-quality stainless steel. Stainless can handle the steel wool much better than thin chrome plating can.
06

Keeping the Shine Alive

Once you've spent an arvo getting those tips perfect, you don't want to be doing it again in three weeks. The secret is regular maintenance. Every time you wash the car, use your leftover soapy water and a dedicated 'exhaust' microfibre to wipe the tips. Don't use your good paint mitt! If you've applied a ceramic coating like Gtechniq C5, you'll find that most of the soot just rinses off with a hose. A customer once brought in a Ranger Raptor he'd taken through the Grampians, covered in mud and soot. Because we'd coated the tips a month prior, the gunk just fell off. If you live in a coastal area like the Gold Coast or Perth, this protection is non-negotiable to stop the salt air from pitting the metal. Every 6 months, give them a light 'top-up' polish with a soft cloth to keep the oxidation at bay. And yeah, that's pretty much it.
07

The Best Gear for the Job

I've tried a lot of junk over the years. Some people swear by Mother’s Mag & Aluminium Polish, and it's alright, but I reckon the **Autoglym Metal Polish** is more versatile for Aussie conditions. For steel wool, just head to Bunnings and look for the 'Grade 0000', it’s usually in the paint prep aisle. If you want the absolute best protection, **Gtechniq C5 Wheel Armour** is the only method I trust for heat resistance. It’s pricey, but a tiny bottle will last you and your mates' cars for years because you use so little. Avoid the cheap 'chrome sprays' from the servo; they're basically just oil that burns off the second you start the engine.
08

Common Questions from the Shed

Can I use Coke and aluminium foil to clean my exhaust?
Look, it's an old school trick, but I wouldn't recommend it for a modern car. The foil can actually be quite abrasive and the sugar in the Coke is a nightmare if it dries. Stick to proper metal polish.
How often should I polish my exhaust?
If it's a daily driver, I'd say every 3 months. If it's a weekend toy, maybe once or twice a year is plenty as long as you wash it regularly.
My exhaust is matte black from the factory, how do I clean it?
DO NOT use metal polish or steel wool on matte finishes. You'll turn it shiny and ruin it. Just use a good degreaser (APC) and a soft brush.
The inside of my exhaust is always black, do I need to clean it?
You'll never keep the deep inside clean, but I always clean about 2-3 inches into the pipe. It makes a huge difference to the 'finished' look of the car.
Will cleaning the exhaust affect my warranty?
No dramas there. Cleaning and polishing the exterior of the tips is standard maintenance. Just don't go shoving things too far up the pipe!
What if my exhaust is rusted?
If it's just surface rust, the steel wool and polish will get it off. If there are actual holes or chunks missing, she's gone, mate. Time for a trip to the exhaust shop.
Is it okay to use oven cleaner?
I’ve seen blokes do this on YouTube. Truth be told, it works on carbon, but it's incredibly harsh on paint and plastic. I’ve seen it ruin the clear coat on a bumper in seconds. Not worth the risk.

Watch Out

Avoid using WD-40 or similar oils as a 'protectant' on your exhaust. As soon as those pipes get hot, the oil will smoke, smell terrible, and actually attract more dust and dirt. It can also 'bake' onto the surface, making your next clean twice as hard.
