We recommend rinsing your NIMAL cup before your first use, and washing regularly to keep it in tip top condition. To clean, squeeze the silicone cup into a “C” shape to separate the collar as well as the heat sleeve, and unscrew the lid. You can wash your NIMAL Cup by hand with warm water and mild soap, or place it on the top rack of your dishwasher.
Since NIMAL cups are made of platinum food grade silicone, it is normal to have a natural silicone smell before your first use. Some strong-smelling foods and drinks may also leave residual fragrance or taste on your NIMAL cup.
Here are some simple ways to remove any lingering aromas or tastes:
1. Place your silicone cup in boiling water to sterilize and remove strong odors (NOTE: Please remove all plastic components; lid, collar and heat sleeve before boiling your NIMAL cup).
2. Submerge the cup in a mixture of hot water and white vinegar using the ratio of one cup vinegar for every two cups of hot water. Soak for 30 minutes, then scrub gently with a cleaning sponge.
3. Coat your NIMAL cup with a mixture of white vinegar and baking soda using the ratio of one tablespoon of white vinegar to two tablespoons of baking soda. Allow the coated cup to sit overnight. Rinse with water to completely remove the mixture and dry thoroughly.
