I can't fit one of my giant mitts in my tiny mouth let alone the two required to properly hold floss. I hate using the disposable floss picks because of the plastic waste. So for a long time I could just never floss properly unless I wanted to make a pile of plastic waste.
I did get a water pick now though and that works nice. Also to all the people who say water picks don't clean as well as floss I say, you may be right but also that thing can blast limescale off of my sink so I'm pretty sure it does a good enough job on my teeth.
I use the 10 setting to clean limescale off my sink. I'm pretty sure it could strip latex paint if you tried.
