That’s good. A little bit goes a long way.
A few Oz in a empty Bleach bottle with Water and You have Clorox refilled.
Be sure to store it safely, on the floor level in a plastic Tote or Bin for extra safety. Do not let any organics come in contact with it. It can start a fire coming in contact with organics. Oil, Soda (Coke), flour, etc.
