Laundering - How to Clean White Lab Coats

Though the lab coat is worn as an overcoat, it accumulates microbes and dirt that is not always visible. For safety, it’s best to wash lab coats often. A load of one or more white lab coats together should be washed weekly, as a dedicated load.

  • For your personal safety, use disposable gloves when handling lab coats containing unknown pathogens.
  • Set your washing machine to the hottest water setting possible, checking the fabric wash label first.
  • Check all pockets for pens, tissues, and other items.
  • Wash medical clothing separately, being sure to keep whites together.
  • Use a detergent such as Tide or Persil (see list of recommended products below). For extra brightness, use an oxygenated laundry soap.
  • Do not use fabric softeners in order to keep the lab coat bright and add to the longevity and efficacy of high-tech fabrics.
  • Pre-treat stains with stain removers.
  • After washing, wipe down the washing machine with disinfectant.

Treating stains - How to Remove Stains from Lab Coats

It’s best to treat the stains as soon as possible. To get out stubborn stains, soak lab coat in cold water with a ¼ cup of or scoop of oxygenated detergent. Rub the stained area with the solution, then let it soak overnight. The next day, wash lab coat as you normally would, and if the stain is still visible, pre-treat with a stain remover such as Shout or Resolve.

  1. Ink stains – Ballpoint ink stains don’t have to be the end of your white lab coat. If you’ve gotten ink stains on your lab coat you have likely wondered, “how to get pen out of white lab coats?” Take heart, it can be done! As soon as you get ink on your coat, do not try to clean or rub the area.
  • Once you get it home, assemble the following items to help remove the ink: paper towels or clean rag, rubbing alcohol, your stained lab coat.
  • Place a paper towel under the stain, with additional paper towels or a clean rag, blot the area with a generous amount of rubbing alcohol. Blot until the ink dissolves or disappears, changing the blotting rag often. Wash immediately.
  • When washing cycle is completed, check to see if stains persist. If still visible, treat with spray stain remover, then wash again, using a strong detergent.
  • Blood stains - To remove blood stains from a white lab coat, first run blood-stained areas under cold water for a few minutes, removing as much blood as possible.
    • Place a few paper towels under the stain.
    • Using a clean rag, cotton gauze or paper towels, blot spot with hydrogen directly on top of the stain.
    • You may need to blot a few times until the stain is lightened. After blotting, soak the lab coat in cold water and a scoop of oxygenated laundry detergent overnight.
    • If blood stains persist, blot with hydrogen peroxide again, then with a clean white cloth on the stain, gently place a warm iron on top of the area for a few moments
  • Protein stains – Vomit, feces or urine stains need to be treated before washing.
    • With gloved hands and a piece of cardboard, tongue-depressor, or other item for scraping, remove excess protein from the lab coat.
    • In a large bucket of cold water add and dilute a ¼ cup enzyme detergent and ¼ cup baking soda. Soak coat for a minimum of one-hour. Baking soda helps reduce odors. Remove from solution and wash as usual.
  • Food stains – Oil-based food stains need to be pre-treated with a liquid or spray stain remover.
    • In some cases, it’s best to soak a white lab coat in hot water and an enzyme detergent. Then wash as usual.
    • After removing from the washing machine, check to be sure stains are removed. If not, re-treat stains with liquid or spray stain remover and wash again. It can take a few washes to get especially tough stains out.
