The Before-And-After Photos Prove It: Just 28 Of The Best Cleaning Products You’ve Ever Seen

Promising review:If you have a steel bottle, Yeti, whatever bottle, YOU NEED THESE!!! Those bottles aren’t supposed to be cleaned in the dishwasher, and handwashing never seems to get them clean enough. These are amazing. I usually fill the bottle about half full with the hottest water I can, drop in the tablet (or two, depending on the size of the bottle), fill the bottle nearly to the top, put the lid on and let the tablet work. I usually let it sit for at least an hour, rinse it out, and it’s perfect. I’ve even used these on a to-go coffee cup I found that had coffee for who knows how long (it was gross). I used two tablets, and it was sparkling…I don’t know how many times I’ve re-ordered these…and I will keep re-ordering them as long as I have any double-walled/steel bottles…fabulous.” —Nannon
