[DCHAS-L] Old Bleach
Bleach, one of my favorites: If it has TRULY remained sealed (no seam cracks or cap gaps) it should be fine. If otherwise, you may just have sodium bicarbonate, as carbon dioxide in air replaces the chlorine. At least give it a sniff (carefully).

Subject: [DCHAS-L] Old Bleach
Hello,
I was wondering about using old stocks of bleach for disinfecting in bio labs. The bleach is about 2 years old and has never been opened. I am not sure if it is industrial or commercially available bleach. Any advice would be appreciated.
