Quick answer

Drop one S'well Cleaning Tablet into your bottle, fill with warm water, and let it fizz for 15-20 minutes. Rinse thoroughly and air dry. These tablets are formulated specifically for S'well's triple-insulated stainless steel to remove residue without damaging the finish.

Why Use Cleaning Tablets for Your S'well

Over time, even well-rinsed bottles can develop lingering odors or a faint film from coffee, tea, or flavored water. Regular dish soap may not fully break down these residues inside narrow bottles. S'well Cleaning Tablets are designed to tackle this without scrubbing, reaching areas a brush might miss. They are specifically formulated for S'well's triple-insulated stainless steel, so you won't risk damaging the exterior finish or the vacuum seal. A quick tablet soak once a week keeps your bottle fresh and ready for daily use.

What You'll Need

To get started, grab your S'well bottle or tumbler, one S'well Cleaning Tablet, and warm tap water. No extra tools or harsh chemicals are required. The tablet format simplifies the process, making it easy to maintain your reusable hydration bottles without a lengthy routine.

Step-by-Step: How to Clean with S'well Cleaning Tablets

  1. 1. Fill your bottle with warm water: Remove the cap and fill your S'well bottle or tumbler about three-quarters full with warm tap water. Avoid boiling water, as extreme heat can stress the vacuum seal over time. Checkpoint: Water should be warm to the touch, not hot. If it steams, let it cool slightly before proceeding.
  2. 2. Drop in one cleaning tablet: Drop one S'well Cleaning Tablet into the water. It will start fizzing immediately, releasing cleaning agents that break down residue and odors inside the bottle. Do not use more than one tablet per cleaning session. Common mistake: Adding two tablets won't double the cleaning power and may leave excess residue. Stick to one.
  3. 3. Let it soak for 15–20 minutes: Allow the tablet to fizz and soak for 15 to 20 minutes. For tougher stains or odors, you can extend the soak up to 30 minutes. Do not let it sit overnight, as prolonged exposure may dull the finish. Checkpoint: Set a timer. Soaking too long can affect the bottle's appearance, while too short a soak may not fully clean it.
  4. 4. Pour out the solution and rinse thoroughly: Pour the used solution down the drain. Rinse the bottle and cap several times with clean, cool water until no suds or tablet residue remain. Any leftover cleaning solution could affect the taste of your next drink. Common mistake: Skipping the rinse step leaves a faint chemical taste. Rinse until the water runs clear and odorless.
  5. 5. Air dry completely before reassembling: Place the bottle and cap upside down on a drying rack, or leave them open in a well-ventilated area. Allow all parts to dry completely before putting the cap back on. Trapped moisture can lead to mold or mildew inside the cap. Checkpoint: Drying usually takes 1–2 hours. If you're in a hurry, use a clean, lint-free cloth to dry the interior and cap threads.
