What is the peaceful way to get rid of bad breath in Ramadan without breaking the fast?

The Shafi'i school held the view that it is disliked for a fasting person to remove bad breath with a siwak at the end of the day, citing the hadith (definition): "The smell of the fasting person's mouth is sweeter to Allah than the scent of musk." As for the majority of scholars, they did not dislike the removal of bad breath with a siwak or other means, and this is the stronger opinion. The best way to remove bad breath is by using a siwak, or any means from which nothing enters the fasting person's stomach.
