“BLEACH” was first heard on Billy Star, a short film released by the band on December 12, 2017. Three days later, the song was officially released on SATURATION III as the seventh track.

Every member’s addition to the song seems to relate to an internal or personal struggle that they deal with. Bleach is not only a powerful cleaner, but it also can act as a stain remover and a whitener for what may have seemed to be a ruined white piece of cloth. This could relate to each member wanting to wipe away their own issues, with bleach being a metaphor for that desire.

The song features collaborator Ryan Beatty, and is the second BROCKHAMPTON song to feature him, as he previously appeared on “QUEER” from SATURATION II.

At the time, BLEACH was the only song that featured all seven performers.
