First used：
Open the package, pour the mixed liquid of white vinegar and water into plastic bottle(1 :4 ratio). Close the cover, shake for 10 seconds, open the cover, place for 15 minutes, and then wash the bottle and hydrogen stick repeatedly until the water become clean, then it can be used normally.

Washing method:
Washing the alkaline water stick according to the above method once a week, change the water at least every three days.

How to use it?
1. Before using, put the stick in a clean bottle filled half-way with tap or bottle water(if bottled, preferably one with a 7 pH or higher). (If stick is covered with plastic wrapper, please remove) Shake vigorously for 30 seconds and dispose. This removes excess loose minerals. Repeat 2 more times.
2. Fill the bottle again with water shake vigorously for 30 seconds and wait 15-20 minutes before drinking. The longer the water sits with the ionic stick submerged, the stronger the ionization and the higher the pH (up to pH 9.5) Also a strong negative charge(ORP) is attained,can to -250If it tastes too strong, dilute it a bit with additional source water.
3. Use one stick for a 16 oz bottle (500ml). Use two sticks for a quart (1 liter) bottle, or more sticks for faster, stronger ionized drinking water.
4. Best to drink freshly made ionized water, and drink often!
5. It can use about 300 times. The deadline of time is an approximate time based on how much water you drink. We suggest getting new ones every 6 months
