Get the Clearest Ice

Tips & Tricks

Tip: Contrary to common sense, hot water freezes quicker than cold water, which can result in foggy ice.

Slow Freeze

Slowing freezing time will help produce clearer ice; the faster the ice freezes, the more impurities are trapped in the ice. You can achieve this by insulating the ice tray during the freezing process. The Clear Duos already have an insulator to create the clearest ice. If you place the tray in a small cooler with about 2" of water at the bottom, then freeze the cooler, you can get much clearer ice.

Distilled Water

Using distilled or filtered water will help create clearer ice. This is due to the lack of impurities in the water. With fewer impurities, light can pass through your ice with no obstructions, making them super clear.

Boil Water First

If you don’t have access to distilled or filtered water, try boiling your water and letting it sit until it reaches room temperature. This removes air bubbles from the water, allowing the molecules to stick together in the freezer, helping you get clearer ice.

Cleaning Tips

What causes white residue

The compound associated with the residue is Calcium Sulfate – meaning the residue is associated with the chemicals in hard water, like a mineral deposit. The minerals from the water calcify and adhere to the walls of the silicone and are then transferred to the surface of the next ice cube to be made.


White residue is completely harmless.

How to clean it

We have found a dilute solution of vinegar and water to be a great solution. Simply soak the trays in this for about 20 minutes, rinse your product, and you’re ready to go.


These tips will also help in removing residue left over by soap-based cleaners.

Helpful Hints

Sphere Tips

Use the back of a butter knife to whack off the ice tips on the sphere ice molds

Let Rest

Allow the ice to sit at room temperature for a few minutes. This will allow ice to temper and will help avoid cracking when liquid is poured over ice.

Colder Freeze

Sometimes ice from ice spheres will have cracks; this is because the ice was frozen too quickly. To prevent this, try turning up your freezer's temperature.
