The term “dissolve” is a bit of a misnomer here. Toilet paper doesn’t truly dissolve like salt in water. It disintegrates or hydrolyzes . The goal is to sever the hydrogen bonds and break the long cellulose polymer chains into smaller, water-soluble fragments or simply to separate the fibers so completely that they can no longer hold together as a mass. Three primary chemical approaches exist, each with its own household champion.
Chemical dissolution is almost always followed by mechanical rinsing. After the dwell time, fill a bucket with very hot (but not boiling—boiling water can crack porcelain) tap water. Pour it into the toilet bowl from waist height. The force and heat will help flush the chemically-weakened, partially dissolved paper through the trap and into the main drain. dissolve toilet paper clog
