How to Clean Up a Used iPhone or MacBook Before Reselling

If you want to clean a used iPhone or MacBook before flipping it, you don’t need fancy tools—just the basics. Here’s what I use every time.

Let’s be real—when you’re flipping Apple gear, presentation matters. People will pay more for a device that looks clean, even if it’s the exact same product as a dusty one.

Here’s how I clean up used iPhones and MacBooks to make them look as close to new as possible—without spending more than a few bucks.

My Routine for Cleaning Used Apple Devices

1. Turn it off first

Safety first. You don’t want to accidentally trigger SOS or FaceTime someone while scrubbing.

2. Use a microfiber cloth and a bit of 70% isopropyl alcohol

• Don’t soak it—just dampen the cloth slightly
• Wipe the screen, back, and sides
• Especially around the camera lens

3. Toothpick or SIM tool for port dust

• Gently clean the charging port and speaker grills
• You’d be shocked how much lint comes out

4. Magic Eraser for tough grime (carefully)

• Only for metal edges or scuffs—not for the screen or glossy parts

5. Remove old screen protector (if nasty)

• A $2 replacement makes it look brand new
• If it’s clean, leave it on and say “free protector included” 😎

MacBook Cleaning Checklist 💻

1. Power it off and unplug everything

• Common sense, but worth repeating

2. Compressed air or soft brush for the keyboard

• Turn it upside down and tap gently
• Air helps get crumbs out of tight spots

3. Microfiber cloth with alcohol for outer shell

• Wipe screen, keyboard, trackpad, and outer case

4. Magic Eraser (again) for palm rest discoloration or gunk

• Works wonders on older MacBooks

5. Tighten loose screws if needed

• Especially on bottom case—use a tiny pentalobe or Torx driver

Extra ByteFlip Touches

• If you don’t have the original box, you can buy empty ones on Kijiji for about $5. Just be honest—say it’s a replacement phone, or that the box is from a similar model one of your family members used. This goes for MacBooks too—box presentation helps add that “I took care of this” vibe.
• Bonus points if you include unused accessories (don’t toss in oily used cables—nobody wants that). A clean, unused charger and cable helps make the iPhone or MacBook feel legit and cared for.
• Take listing photos after cleaning, with good lighting
• Use a neutral background (desk or wood grain works)
• Take closeups of the ports and screen to show it’s clean
• Mention in the listing: “Sanitized and ready to go.”

A few minutes of effort can add $20–50 in perceived value. Not bad for some rubbing alcohol and a cloth you got free with your glasses 🤓
