Zard from San Jose, Ca writes
If I open a container of Boracare and only use 1/3, how long can I store the remaining 2/3 of undiluted Boracare that is in the container?
Undiluted Bora-Care should be used within three years of the date of purchase. Once diluted, Bora-Care should be used immediately. Bora-Care that is left for more than a few hours after it has been diluted will start to separate from the water and will be impossible to get back into a proper diluted form.
