Review on Beesly's Bottle Wash: Natural Daily Sports Bottle & Container Cleaning Soap | Biodegradable, Chlorine-Free 🌿 | Safely & Quickly Cleans, Removes Odors from Reusable Bottles | Cleans Over 200 Containers! | 12oz by Jason Williamson

The stuff really works! Every stainless steel water bottle or insulated mug I've used these on looks BRAND NEW on the inside. I followed the instructions by dropping the hot water capsule. I soaked the really hard soiled bottles/cups overnight, swept the bottle brush and then rinsed thoroughly. Like I said, it looks shiny and new. I'll have to see if they offer smaller pods for 16oz or less insulated stainless steel, these pods seem oversized for the smaller cups. I solved this problem by cutting it in half (keeping one of the cups) and dividing a pod into two smaller vessels. After thorough rinsing and drying, I could not detect any aftertaste.
