There is no scientific consensus on the effects of bleach on poop, but most experts believe that it doesn't dissolve it completely. Some people think that bleach might cause some plastics to break down, which could release the poop inside the plastic bag. Others believe that bleach might cause some colors to fade, which could make the poop look different to the naked eye. Ultimately, it's up to the individual to decide whether or not they want to use bleach to clean their poop.
