How Long Can Urushiol Stay on Clothes?

Urushiol is the oily resin found in poison ivy, oak, and sumac plants that can cause an itchy and sometimes painful rash in many people. If you come in contact with plants containing urushiol, it’s imperative to remove it immediately to minimize the chance of a reaction. The question then becomes “How long can urushiol stay on clothes?”

Short-Term Effects of Urushiol on Clothes

When urushiol comes into contact with the skin, it can cause an immediate reaction. The same is true for clothing. If urushiol resin is allowed to soak into clothing, it can cause a reaction and an accompanying itch. Here’s what to watch out for:

  • Symptoms: Urushiol can cause skin rashes, itchiness and inflammation. If you come into contact with urushiol and start to experience these symptoms, this is a sign that you should immediately remove any clothes that may have come into contact with it.
  • Duration: Urushiol typically stays on clothing for a few hours after contact, although this may vary depending on the level of exposure.

Cleaning Urushiol from Clothes

The best way to get rid of urushiol on clothing is to wash them with a detergent that is specifically designed to break down and remove urushiol resin. This detergent can be found at most hardware stores.

Also, be sure to use hot water when washing your clothes as this will help break down the urushiol resin. Once you have washed the clothes, check to make sure that the urushiol has been removed.

If the urushiol residue is still present, then you should repeat the washing process with even more detergent until it has been completely removed.

How Long Can Urushiol Survive on Clothes?

On average, urushiol can survive on clothing for up to a few days. However, this may vary depending on the amount of contact and the fabric of the garment.

In general, fabrics such as nylon, rayon and silk are most likely to retain urushiol resin for extended periods of time, while fabrics such as linen, cotton and wool may release the resin quicker.


Knowing how long urushiol can stay on clothing is important for avoiding reactions.

If you come into contact with urushiol, it’s best to remove affected clothing as soon as possible to minimize the chance of a reaction. Additionally, you should always wash your clothing after contact to ensure that any residue is removed.

Remember: the sooner you act, the better.
