Related: The 6 Best Hardside Luggage, Tested at the Gate
Well, is a hardside suitcase really "scratch-proof" like the marketing says? I've been throwing bags for a living since before you had to take your laptop out at security, and I can tell you the answer is no.
I've spent the last four years reviewing luggage full time after six years at the gate at O'Hare, and my current rotation includes an 11-bag lineup that gets dragged through at least 120 segments a year.
The short version: every polycarbonate shell gets scratched. It's a fact of the belt. But fixing them is easier than most people think, and I've got a few methods that actually work.

I don't review a product until I've lived with it for at least three months. For scratch removal, that means I've tested these methods on my own bags, the ones I fly with every week. My 70-pound lab mix Juno has slept on the softside bags in my rotation, but the hardside shells get the runway test: packed full, thrown down stairs, run through five real flights, and checked for damage after.
The bag that started this whole obsession was a $600 polycarbonate shell that dented on its second flight. I was furious. Then I realized the dent was fixable, and I've been testing removal methods on every scratched bag I own since.
The truth about polycarbonate scratches
Here's what I know from the repair shop I worked at before the airline gig: polycarbonate is a thermoplastic. That means it can be reshaped with heat. Scratches are different from dents. A scratch is material removed. A dent is material displaced.
The mistake most people make is treating every mark the same. A scuff from a rubber conveyor belt is just transfer. A light surface scratch is in the clear coat. A deep gouge is through the shell. Each needs a different fix.
Method one: the Magic Eraser for scuffs
I was skeptical about this one. A melamine foam sponge for luggage? Seemed too simple. Then I watched a black scuff from a baggage cart disappear off my gray Away carry-on in about thirty seconds.
The scuffs that come off the belt are mostly rubber transfer from the conveyor belts and bumpers. They sit on top of the shell, not in it. A damp Magic Eraser lifts them right off. No chemicals, no elbow grease, no risk of making things worse.
I've used this on three bags in my rotation: the Away, a Monos, and a cheap Amazon Basics carry-on that scratched but didn't break. It works on all of them. The key is to keep the sponge damp and use light pressure. Let the sponge do the work.
The limit: Magic Eraser won't touch a real scratch. If you can feel it with your fingernail, this isn't your fix.
Method two: Novus 2 for light scratches
Novus is what I used in the repair shop. It's a plastic polish that comes in three grades. Novus 1 is a cleaner. Novus 2 is a fine scratch remover. Novus 3 is for deep scratches and requires more skill.
I use Novus 2 on any hardside bag that's picked up light surface scratches. The process is simple: apply a small amount to a microfiber cloth, rub in a circular motion, buff off. It takes a few passes on deeper marks, but it works.
The catch: Novus 2 won't fix a crack or a gouge. It's for surface scratches in the clear coat, not structural damage. And it takes time. I spent about twenty minutes on a scratched Delsey shell and got maybe 80 percent of the marks out. The deep ones stayed.
For the money, Novus 2 is the best polish I've found. A bottle lasts a year of regular touch-ups.
Method three: heat for dents and deep scratches
This one's the gate agent trick. Polycarbonate has memory. When you heat it, it wants to return to its original shape. That's why you can fix a dent with a hair dryer or heat gun.
I tested this on a $300 hardside that got crushed in the overhead bin. The dent was about the size of a golf ball. I used a heat gun on low setting, held it about six inches from the shell, and moved it in a circle. After about two minutes, the dent popped back out. It wasn't perfect. There was a slight ripple in the surface. But it was 90 percent better.
For deep scratches, heat won't remove material. But it can soften the edges of a gouge so the scratch looks less severe. I've done this on a bag that got dragged across the tarmac, and it made a difference.
The warning: don't overdo it. Polycarbonate melts. I've seen bags ruined by people holding a heat gun too close for too long. Keep the heat moving and check the surface constantly.
Method four: automotive rubbing compound
This is the budget option. A bottle of automotive rubbing compound costs less than half of Novus, and it works on the same type of light surface scratches.
I used it on a cheaper polycarbonate shell that had picked up scratches from being stacked under heavier bags in the hold. The compound took out the light marks, but it was more aggressive than Novus. On a bag with a soft-touch coating, it ate through the finish. That's a real risk.
Use this only on bare polycarbonate shells, not on bags with a textured or coated surface. And test it on a small area first.
Method five: toothpaste, the last resort
The toothpaste trick is all over the internet, and I'll admit I tried it. It works on very light scuffs, the kind you can barely see. It's not better than Novus, and it's messier. You have to rub it in for several minutes and then wipe it off.
I'd skip it unless you're in a hotel room with no other option. It's a workaround, not a fix.
What doesn't work
I've tried the stuff that doesn't work so you don't have to. WD-40 removes some scuffs but leaves a greasy film that attracts dirt. Shoe polish covers scratches but rubs off on your hands and clothes. Nail polish remover will eat the polycarbonate and leave a cloudy mess.
And the biggest lie of all: scratch-proof luggage. It doesn't exist. Every hardside bag gets scratched. The question is whether you can fix it.
The bottom line
The Magic Eraser handles scuffs. Novus 2 handles light scratches. Heat handles dents. That covers 90 percent of the damage a hardside bag will see in normal use.
I don't track prices day to day, so I won't pretend to know next week's Amazon deals. What I know is that a $1.50 Magic Eraser and a $12 bottle of Novus 2 will keep your hardside looking decent for years. That math works out to pennies per trip.
Here's my honest bottom line: your hardside bag will get scratched. It's going to happen on the belt, in the bin, or in the back of a taxi. Don't buy a new bag over it. Buy a Magic Eraser and a bottle of polish, and spend twenty minutes fixing it. That's what I do with every bag in my rotation, and they all still look good enough to roll through the terminal without embarrassment.
