Ink stains are among the most common in medical settings: pens exploding in pockets, caps that don't close properly, or a lapse in routine. Although they seem impossible to remove, most can be eliminated using the correct methods.

Here's a clear and effective guide to recovering your scrubs without damaging them.


Why is ink so difficult to remove?

The ballpoint pen ink is formulated to attach to surfaces and resist water. When it falls on fabrics such as cotton, polyester, or blends, it penetrates quickly and adheres to the fibers, requiring products that dissolve it without affecting the uniform's color.


What to do immediately after the accident

Quick action prevents the ink from spreading:

  • Pat dry with a paper towel without rubbing.
  • Place a clean cloth under the fabric to prevent the stain from soaking through.
  • Do not use hot water (it spreads the stain).
  • Do not put the garment in the dryer before cleaning it.

This prepares the fabric for the appropriate treatment.


Effective methods for removing ink stains

1. Isopropyl alcohol: the fastest and safest method

It is the most recommended treatment for fresh ink.

How to apply it:

  • Moisten a cotton ball or cloth with alcohol.
  • Dab the ink onto the stain, allowing it to transfer to the cotton.
  • Repeat until the color fades.
  • Wash the garment as usual.

It works well on polyester scrubs or blends.


2. Hairspray (fixative spray)

It contains alcohols that help dissolve dried ink.

How to use it:

  • Spray directly onto the stain.
  • Leave on for 1–2 minutes.
  • Rub gently with a cloth.
  • Rinse with cold water and wash.

Ideal when you don't have alcohol on hand.


3. White vinegar + liquid detergent

Gentler option for delicate fabrics or sensitive colors.

How to use it:

  • Mix 1 part vinegar and 1 part detergent .
  • Gently rub the stained area.
  • Leave on for 10 minutes.
  • Wash normally.

Helps loosen medium-sized stains without discoloring the fabric.


4. Baking soda (for stubborn stains)

It serves as a gentle exfoliant when residue remains.

How to use it:

  • Make a paste with baking soda and water.
  • Apply it to the stain.
  • Rub in circular motions.
  • Rinse and wash.

Not recommended for very dark or delicate scrubs, as it can damage the fabric if rubbed too much.


5. Professional stain removers

If the dye takes days or the garment is expensive:

  • Use enzymatic products.
  • Oxygenated treatments.
  • Specialized stain removers for ink.

They are a good option for high-end uniforms or sensitive colors.


Tips according to the type of fabric

Cotton

It absorbs more ink.
→ Alcohol + detergent is the most effective.

Polyester or blends

It expands less, but retains pigments.
→ Alcohol or hairspray work very well.

Elastic fabrics

Avoid rubbing too hard.
→ Use gentle methods like vinegar + detergent.


Mistakes that worsen the stain

Avoid these steps if you want to save your uniform:

  • Rub firmly at first (the ink will spread).
  • Add hot water.
  • Mixing chlorine with ammonia (dangerous).
  • Use a dryer before removing the stain completely.

Once the ink is set with heat, it is almost impossible to remove.


How to prevent ink stains on your uniform

  • Use bulletproof pens (pressurized pens or sealed gel pens).
  • Store pens in external pockets or accessory pouches.
  • Always close the lid before putting it in your pocket.
  • Avoid using pens or liquid inks during the day.

Small habits that extend the lifespan of your scrubs.
