How do you disintegrate a sponge in a drain?

To disintegrate a sponge in a drain, you can first cut it into smaller pieces to facilitate breakdown. Then, run hot water down the drain to help soften the sponge further. Adding a mixture of baking soda and vinegar can also aid in breaking down the sponge material. However, it's important to note that disintegrating a sponge in a drain may not be environmentally friendly, and it's better to dispose of sponges in the trash.
