If you’re using a toilet that’s not flushable, it’s important to clean the caulk around the toilet. This will help prevent water from getting into the toilet and causing problems. To clean the caulk, use a plunger to push and pull the caulk out from between the toilet and wall. Be careful not to damage the wall or toilet. To clean the inside of the toilet, use a plunger to push and pull out any built-up dirt and debris. Be careful not to damage the inside of the toilet or flooring.
