Using Vaseline on a toilet flapper is not recommended as a long-term solution. While Vaseline might temporarily create a better seal due to its viscous nature, petroleum-based products can actually degrade the rubber or plastic of the flapper over time, leading to more significant leaking issues. For a durable fix, it's best to replace the flapper with a new one designed for your specific toilet model.
