Why Lab Coats Get Dirty?

Lab coats protect you from spills and germs. But in doing so, they get dirty. Here are some common ways lab coats get stained:

• During medical work like surgeries or blood tests
  
  
• When writing with pens or markers
  
  
• While eating or drinking during breaks
  
  
• From sweat during long working hours
  
  
• By accident when using disinfectants or cleaning agents
  
  

General Tips Before Removing Stains

• Always check the label on your lab coat before washing it
  
  
• Try to clean stains as soon as possible
  
  
• Use cold water first to avoid setting the stain
  
  
• Do not put your coat in the dryer until the stain is gone
  
  

Now let’s talk about different stains and how to remove each one.

Blood Stains

Blood stains are common for doctors, nurses, and lab workers. To remove them:

4. Wash with cold water and mild detergent.
   
   
5. If the stain is still there, repeat the steps.
   
   

Ink Stains

Pens can leak, and ink stains are hard to hide. Here’s how to clean them:

1. Put a paper towel under the stain.
   
   
2. Dab rubbing alcohol or hand sanitizer on the spot.
   
   
3. Gently blot the area with a clean cloth.

3. Apply it to the stained spot.
   
   
4. Let it sit for 5–10 minutes.

Quick Touch-Ups

If you are at work and get a stain:

• Use a stain remover pen (keep one in your pocket).
  
  
• Blot the stain, don’t rub it hard.
  
  

Drying the Lab Coat

Never dry your coat in the dryer if a stain is still there. Heat can make the stain permanent. Always air dry first and check the stain.

When Should You Replace a Lab Coat?

Sometimes, cleaning is not enough. You may need to buy a new lab coat from Knya if:

• The coat has holes or thin fabric

Keeping your coat fresh shows that you care about safety and cleanliness.
