What to Do If a Pen Explodes in Your Bag or Pocket

Last updated on June 1, 2025

(Ink Removal Tips for Bags, Linings, Leather & More)

It starts with a small smudge. Before you know it, your bag, jacket, or jeans are soaked in ink — and the culprit is a pen that’s gone rogue. Whether it’s a cheap ballpoint, a leaky fountain pen, or a gel pen that exploded from pressure, an ink leak is messy, frustrating, and all too common.

The good news? It’s fixable — if you act quickly. Here’s exactly what to do when a pen leaks or explodes in your bag or pocket, plus how to remove ink stains from different materials and prevent future disasters.


Step 1: Act Fast — Don’t Let the Ink Set

Bold text on yellow background reading “Immediately remove the pen and any ink-stained items” — a reminder to act fast after a leak.

If your pen exploded in your bag, speed is key. Ink stains can soak deep into fabrics, linings, or leather, making them harder to remove later.

  • Take everything out of the bag immediately.
  • Remove the leaking pen and blot up any liquid ink with paper towels or tissues.
  • Don’t rub — this spreads the stain and pushes it further into the material.

Step 2: Isolate the Mess

Text graphic that says “Clean the stain with a damp cloth” on a light blue background — a quick tip for ink stain treatment.

Once the pen is out and you’ve blotted the worst of the spill, separate the affected items. If a notebook, wallet, or phone case got ink on it, set it aside for cleaning.

Use a clean towel or napkin under the stained area to absorb any ink that might seep through while you work.


Step 3: Remove Ink Based on the Surface

👜 Leather or Faux Leather

For leather bags, seats, or jackets:

  1. Dampen a soft cloth with warm water and mild soap.
  2. Gently wipe the ink-stained area.
  3. For stubborn stains, use a cotton swab dipped in rubbing alcohol or hand sanitizer.
  4. Always test a small area first.
  5. Finish with leather conditioner to restore suppleness.

🔲 Plastic, Vinyl, and Hard Surfaces

Ink on plastic pencil cases, lunchboxes, or coated bag linings?

  • Use an alcohol wipe or cloth soaked in rubbing alcohol
  • If needed, apply a bit of acetone (nail polish remover), but be cautious — it may damage finishes
  • Rinse with soapy water to remove residue

Step 4: Clean Ink Off Your Hands

Blue-stained fingers? Don’t worry — ink on skin is harmless but annoying.

  • Wash with warm water and soap
  • For stubborn ink, use toothpaste, lemon juice, or a baking soda paste
  • Avoid harsh chemicals on skin — they can irritate

Step 5: Salvage or Toss the Pen

If the pen was cheap or cracked, throw it away. But if it’s a refillable gel pen or a fountain pen, it may just need cleaning:

  • Disassemble the pen if possible
  • Rinse each part with warm water
  • Let it dry completely before reuse

  • Avoid leaving pens in hot environments like cars or sunny windowsills

No, it’s not. Everyday pen ink — whether from a ballpoint, rollerball, or gel pen — is non-toxic in small amounts. Getting ink on your skin or even accidentally touching your mouth won’t cause ink poisoning.
