Tips and Tricks:
Wash the water vessel (clear plastic part) and the silicone trays before using to make ice. Both of these components are dishwasher safe.
- No need to wash the black foam housing.
Use hot water to fill OnTheRocks. Hot tap water works well, but if your water has a high mineral content the ice may become a bit cloudy at the edges.
- You can get rid of this by using filtered or bottled water. Just bring it to a boil and pour it straight into the water vessel.
- DON’T use distilled water. It will end up very clear but have a few big bubbles right in the center of the ice…i would love if someone could explain why this happens; I haven’t figured it out.
Make sure to tap the top of the spheres and diamonds to avoid trapping air bubbles.
Make sure the bottom of the trays (especially the cubes) are flat (horizontal). If one corner is higher, it will cause that cube to grow vertically…which I think is actually kind of cool.
It will take 20-24 hours to freeze; this depends on how hot the water is and how cold your freezer is.
- The freezing process is done when the ice freezes down from the top past the holes in the bottom of the tray.
- It will be easier to demold your cubes/spheres/diamonds if you dont let it freeze solid, but its perfectly sage to let it freeze solid. The polycarbonate water vessel is designed to withstand this because it’s inevitable that you’ll forget about it.
The best way to store the ice is in an insulated container (like the water vessel inside the housing, or a cooler) inside the freezer.
- This keeps the ice from shrinking and sticking together through the modern freezers de-frost cycle.
- However, most of the time I use them quickly enough that I just leave them in a drawer or a zip-top freezer bag in the freezer.
Once the ice freezes solid it can actually get much colder than freezing (32 DegF, 0 DegC). This can cause the ice to crack if you drop it directly into a warm drink.
- Personally I think this is a cool effect, but you can avoid it by letting the ice sit out at room temperature (or in the fridge) for about 5 minutes.
