How to use Eye Sauna in Cooler weather
In cooler weather, we recommend heating the distilled water prior to adding it to the Eye Sauna.
This will ensure the Eye Sauna will heat the water to a warmer temperature for optimum benefit to your eyes.
Fill the 10mL filler bottle with distilled water and place the tip/lid on. Half fill a cup with boiled water from a kettle, then carefully hold the filler bottle by the tip in the boiled water for 35-40 seconds.
Please test a small amount of the water on your wrist to make sure of the temperature. It should feel warm but not too hot. Fill the Eye Sauna with the heated water and it will continue with the rest of the heating process to create the warm mist.
How Long Should I keep a bottle of distilled water after opening?
Distilled or demineralized water can potentially start to be contaminated with bacteria over time. It would be best to not use any remaining water in a bottle 2 weeks after opening. Try and find the smallest bottle you can to reduce wastage.
