Have you ever wondered how to keep your lab coat looking fresh despite all the spills and stains it encounters every day? For many professionals working in laboratories, hospitals, or any field that requires personal protective equipment (PPE), lab coats are an essential part of the job. But with daily exposure to chemicals, accidental spills, and stubborn stains, maintaining their appearance and functionality can be challenging. To help you keep your lab coat looking sharp and hygienic, here's an in-depth guide on how to tackle different types of stains and ensure it stays in top condition.
Common Lab Coat Stains and How to Remove Them
Blood Stains
Blood stains are one of the most common challenges for doctors, nurses, and laboratory technicians. To effectively remove blood from a lab coat, follow these steps:
- Rinse with Cold Water: Immediately rinse the stained area with cold water. Do not use hot water, as it can cause the proteins in the blood to set, making the stain more difficult to remove.
- Soak in Hydrogen Peroxide: If the bloodstain has dried, soak the area in hydrogen peroxide or apply it directly to the stain. Hydrogen peroxide acts as a mild bleaching agent and helps break down the stain.
- Pre-Treat with Enzyme-Based Detergent: Enzyme-based detergents are effective at breaking down protein-based stains. Apply the detergent directly to the stained area and let it sit for 10–15 minutes.
- Wash in Cold Water: Launder the lab coat in cold water according to the fabric care label. If the stain persists, repeat the treatment before drying the coat.

Iodine and Betadine Stains
Iodine and Betadine are antiseptics frequently used in medical settings. While effective for disinfecting, they can leave stubborn yellow-brown stains on lab coats.
- Blot the Stain: Use a clean cloth or paper towel to blot any excess iodine or Betadine from the fabric.
- Apply Sodium Thiosulfate Solution: Sodium thiosulfate is known for its ability to neutralize iodine. Apply a solution of sodium thiosulfate and water to the stained area and let it sit for a few minutes.
- Rinse and Launder: Rinse the coat thoroughly with cold water, then wash as usual with a standard laundry detergent.
Ink Stains from Pens
Ink stains are a common nuisance for medical professionals who frequently use pens for note-taking. The key to removing ink is addressing it promptly.
- Blot the Stain with a Paper Towel: Place a paper towel under the stained area and gently blot from the top to absorb excess ink.
- Use Rubbing Alcohol or Hand Sanitizer: Rubbing alcohol can help dissolve the ink. Dab a small amount onto a cotton ball or cloth and gently blot the stain. Hand sanitizer, which often contains alcohol, can also work in a pinch.
- Rinse with Cold Water: After blotting, rinse the area with cold water and launder the coat as per the care label.
Sweat Stains
Long shifts can lead to sweat stains, particularly around the collar and underarms. Here’s how to keep your lab coat fresh:
- Pre-Treat with a Baking Soda Paste: Mix baking soda with water to form a paste and apply it to the stained areas. Let it sit for 30 minutes to absorb the sweat.
- Soak in Vinegar and Water Solution: Soak the lab coat in a mixture of one part white vinegar and two parts cold water for 15 minutes to break down any lingering odors and stains.
- Wash with a Mild Detergent: Launder the lab coat with a mild detergent on a gentle cycle.

Povidone-Iodine Stains
Povidone-iodine is widely used for disinfecting wounds and preparing the skin for surgery. If it accidentally splashes onto your lab coat, quick action is crucial.
- Blot Away Excess Solution: Use a clean cloth or gauze to blot the povidone-iodine from the fabric.
- Apply Ammonia Solution: Dilute ammonia with water (one part ammonia to three parts water) and gently dab it onto the stain with a cloth. This will help lift the stain without damaging the fabric.
- Rinse and Launder: Rinse with cold water and wash the coat in warm water using an enzyme-based detergent.
Food and Drink Stains
During a hectic day, it's not uncommon for coffee, tea, or food to spill onto your lab coat.
- Blot Immediately: Quickly blot away as much of the liquid as possible. For greasy food stains, sprinkle baking soda or cornstarch onto the stain to absorb the oil.
- Use a Mild Dish Soap Solution: Dish soap is effective at cutting through grease. Apply a small amount to the stain and gently work it in with your fingers.
- Wash with Warm Water: After pre-treating the stain, launder the coat in warm water to remove any residue.
Handling Stubborn or Set-In Stains
If a stain has set in or remains stubborn despite multiple treatments, consider these options:
- Professional Cleaning Services: Some dry cleaners specialize in medical uniforms and lab coats. They can use advanced techniques to tackle tough stains without damaging the fabric.
- Oxygen Bleach for White Lab Coats: For white lab coats, oxygen bleach is a safer alternative to chlorine bleach. It can effectively whiten fabrics and remove deep-set stains without causing yellowing.
- Stain Remover Pens: Stain remover pens are convenient for quick touch-ups and can be kept in your pocket for immediate use.
When to Replace Your Lab Coat
There comes a point when stains become too stubborn or the fabric becomes worn out. It may be time to replace your lab coat if:
- The coat is discolored or stained beyond repair, affecting its professional appearance.
- The fabric is thinning, has holes, or has lost its structural integrity.
- It no longer fits properly or provides adequate coverage.
Maintaining a fresh, clean lab coat is crucial for upholding hygiene standards and presenting a professional image in the medical field.
