No. Our product will not go cloudy. We do recommend that you purchase our polycarbonate cleaner as this will help avoid cloudiness. The main reason why polycarbonate goes cloudy is due to the cleaner being too harsh on the plastic or the product is left to drip dry. If you would like to know how to better look after your D-STILL Products, please give us a call or shoot us an email.

Using our plastic polycarbonate drinkware around mosquito repellents containing DEET can lead to product damage.

DEET, a common active ingredient in certain brands of insect repellent, has been shown to react with plastics, including polycarbonate.

This reaction can result in the drinkware becoming discoloured, hazy, or even developing cracks. Such cosmetic and structural damage can compromise the overall quality and aesthetics of your drinkware, making it less enjoyable to use.

To maintain the integrity and appearance of your plastic polycarbonate drinkware, we advise to exercise caution and check your mosquito repellents for DEET.

Feel free to reach out to one of our friendly staff members who would be more than happy to assist with any query!
