- 1). Wear plastic gloves when working with hydrogen peroxide. If 35 percent hydrogen peroxide makes contact with skin it will immediately turn it white and cause a stinging sensation. Rinse the skin immediately.
- 2). Fill plastic containers with hydrogen peroxide, filling each container to within 1 inch of the top.
- 3). Seal the containers tightly. Wrap each plastic container in black plastic and secure the black plastic onto the containers with duct tape. Write the contents and the date on the containers.
- 4). Place the containers in the freezer and make sure they stay upright.
- 5). Keep the hydrogen peroxide in the freezer indefinitely.
