Bleach

Bleach is a material that is crafted using a Fabricator. It is used to fabricate Disinfected Water, presumably by killing pathogens in the seawater.

Trivia

 * Bleach used to be crafted with calcium, which was removed when it was replaced by Coral Tube Samples.
 * Although the PDA for Bleach states that it is used for cleaning wounds, there is no way currently to use Bleach to regenerate health.  It is unknown if this will be added in a future update.
