please can someone explain to me the rulings on using mouthwash for hygienic reasons if it contains alcohol. i am not sure if i am posting this in the right section but the other night i read many threads (some regarding the very long mcdonalds debate) about eating foods with certain ingredients such as malt vinegar etc that actually contains a small amount of alcohol. This debate got me quite worried as there were then threads about ketchup etc things i had accepted as being halal. i have gone through all my cupboards and was very disappointed to learn my mouthwash ''listerine'' to be precise has this in it. I m confused so if someone can enlighten me i would be very gratefull.
