“This brush has lots of bristles. Long enough for even the big bottles. It is a little wider then the bottle opening so takes some work but cleans well”
“At first I didn't think it would fit into my bottle! I squeezed it together a bit and in it went. Then pulling it out–be careful! I got sprayed by the bristles as I pulled it out gently. It gets the job done but a little too clunky for the 20oz glass bottles.”
