How should i clean my 9 months baby's tongue??

How I used to clean my baby's tongue was with my finger. Since, the plaque settles on the tongue, you may have to use a little cloth to wipe the tongue. As with a cloth it becomes clean, just the finger cannot take out that thick coating of plaque on the tongue. Also, I would suggest do not use any baby tongue cleaner or anything as of now. And clean the tongue twice, as it cleans the bacteria that causes bad breath.
