Essential ValuesWater Bottle Cleaner - Water Bottle Cleaning Tablets & Reservoir Bladder Cleaner Tabs (24 Tablets) - Tumbler Dispenser Hydration Pack Washer - Manufactured in USA[Amazon-developed Certification] Compact by Design

They work. My husband used and was extremely happy with them.

I had a couple stainless steel coffee mugs. They were probably 10 years old and were badly stained. I tried a few other cleaners with no success. I had to use the tablets twice, but they did work.

I have an insulated water bottle I use throughout the day for water, iced tea, and coffee. So cleaning the bottle, getting it clear of any coloration or taste left over from the coffee can be challenging.But one tablet dropped in the bottle with water and left overnight did a great job of cleaning out any stain or residual taste from the beverages I've had in the bottle.

Just snagged these cleaning tablets, hoping they'll be the magic bullet for keeping my hydration bladder fresh. Made in the USA, with promises of banishing stains and odors from all sorts of containers – even the finicky ones. Twenty-four tablets in the pack sounds promising. Haven't put them to the test yet, but the idea of a simple drop-in solution for a truly clean reservoir is definitely appealing.This review represents my personal opinion and experience with this product.

Hydration bladder still had the table smell to it after several rinsing and scrubbings. I eventually tossed the bladder and bought a new one.

Just finished using the last two tablets in the jar and it lasted since I purchased on 12/28/24. I typically use 1-2 tablets once a week and sit overnight to clean my Simple Modern stainless tumbler in between washing once a week in the dishwasher and the rest of the day’s washing by hand with soap and hot water. I only drink hot black tea in the tumbler so these tablets help keep it bright and clean from the tea stains and bacteria that can build up from normal use. These tablets only have 3 ingredients and are the same ingredients that the Simple Modern company tablets contain at a cheaper price. I find that any other tablets on the market have either harsher chemicals or ingredients that should not be ingested when used and these tablets are safe and effective. Yes, they are small in size but still do a great job!

These tablets are so convenient to clean my reusable water bottle. I saw a video about testing reusable water bottles after only having water in them; the results in the video were shocking and I knew I needed a solution for my personal reusable water bottle. This product solved my problem perfectly! Once a week I dissolve one tablet in my water bottle, fill fully with water, stir, then set next to my kitchen sink overnight. Then rinse in the morning.

These are a life saver for reaching the spots of the bottle that are too deep and/or difficult to reach or scrub well. Cleans my insulated steel beverage bottle very well
