If you have ever been to tropical areas you’ll probably have used DEET. Especially in those regions of the world where malaria is a threat, an effective mosquito repellent is a must. And now that the West Nile virus has made its entrance in the US it may be a required for domestic use too.
Anyone who has sprayed their skin with the chemical repellent and then picked up a nylon jacket or plastic shades may have seen the item fall apart in their hands.
DEET can damage all kinds of synthetic items, from flipflops to water bottles. It may take of your nail polish or disintegrate your tights.
