Laundering Pesticide-Contaminated Clothing for Trainers and Supervisors

Tailgate Safety Training for Landscaping and Horticultural Services
Agriculture and Natural Resources
Agricultural Safety and Health Program

Objective: Launder pesticide-contaminated clothing according to safety guidelines.

Trainer’s Note

Clothing exposed to pesticides must be washed separately and properly. For this module:

  • Review the information below on why and how to launder clothing exposed to pesticides.
  • Have workers discuss what to launder and what not.
  • Review the important points.
  • Have workers take the True/False quiz to check their learning.


Workers should always wear Personal Protection Equipment (PPE) when working with pesticides. However, even with PPE, regular work clothing absorbs pesticides. Your skin can then absorb the pesticides. Clothing can be decontaminated by washing. Pesticide-Contaminated Clothing (PCC) must be washed separately and properly. This also applies to reusable PPE.

Your employer should provide you with clean PPE. You should not take contaminated PPE home for cleaning—it will contaminate your home.

Before Laundering PCC

Read the pesticide label first. It may give directions for the laundering process. All clothing worn while working with pesticides should be considered contaminated. The clothing should be separated from other clothing. Wear rubber gloves when working with PCC. PCC should be washed after each use. It is easier to remove pesticides daily than to remove accumulated contamination. PCC should not be dry cleaned. PCC should not be washed in a public laundromat.

Before laundering PCC, check with local or state agencies for proper disposal of contaminated rinse water.

After taking off clothing, use soap and water to wash your hands, face, neck, and forearms. Then take a shower.

Laundering PCC

  • Pre-rinse or pre-soak clothing. Pre-soak PCC with similar pesticides together.
  • PCC should be washed separately from household laundry.
  • The washer should not be overloaded. Wash a few items at a time.
  • Use only hot water (140 to 160 degrees Fahrenheit).
  • The water level should be on the highest setting. Run a full cycle (12 minutes) using a double rinse.
  • Dry soap should be used to clean dry forms of pesticides. Liquid detergent should be used to clean liquid forms of pesticides.
  • Use 25 percent more soap when clothing has been treated with a soil- or water-repellent finish (i.e., Scotchguard™ or Zepel™).
  • Bleach should not be used. It does not remove pesticide residue. It can react with ammonia fertilizer to form chlorine gas. This can be fatal.
  • All laundered clothing should be line dried. Sunlight will help break down any pesticide residue left in the clothing. Also, line drying will keep the dryer from becoming contaminated.
  • Store PPE clothing in a clean, dry place. Store away from other clothing. Store away from pesticides. Store away from pesticide containers.
  • Clean the washing machine by running the empty washer through a full wash cycle with hot water and soap. This is an important step. If the washer is not decontaminated, other clothing will become contaminated.

Pesticides Cannot Be Removed From

  • Leather boots
  • Leather watchbands
  • Inner bands on caps and some decorative items
  • Severely contaminated clothing


  • Do not wash limited-use coveralls if they have been contaminated with pesticides.
  • Treat contaminated coveralls the same way you would treat the pesticide. Wear gloves and other PPE to protect yourself from pesticide residues within the clothing.

Reusable Coated/Laminated Suits

Suits made from materials such as polyvinyl chloride (PVC) or nitrile should not be decontaminated in a washer. Instead, hose them off. Then wash them in a tub of hot soapy water. Protective clothing made of nitrile, PVC, or other rubber-like compounds should be line dried. However, line dry them in the shade. Sunlight is harmful and will damage the suits. Suits made from plastic, nitrile, or latex may melt if placed in a dryer.

Review These Important Points

  • Pesticide-contaminated clothing should be washed separately from other clothing.
  • Use the maximum water level and the hottest water. Line dry the clothing.
  • Clean the washer with a full wash cycle using hot water.
  • Contaminated coveralls should be treated the same way you would treat the pesticide.
