Dirty bottles? No problem. Just go to town with this all-purpose bottle brush. Measuring 17 inches in length, this bottle brush will easily reach the bottom of most bottles, including 12, 16 and 22 oz bottles as well as 750 ml wine bottles. Disclaimer: if your “friend” gives you a moldy, crud-encrusted bottle with multiple layers of dust and a cigarette butt festering in the primordial swill, well, let’s just say it’s time to retire the bottle.
