HOW TO CLEAN THE OASIS STAINLESS STEEL TUMBLER

CLEANING INSTRUCTIONS

The Ello Oasis Stainless Steel Tumbler is designed for everyday use: leakproof, cupholder-friendly, and perfect for cold drinks on the go. Available in 14oz, 18oz, 24oz, 30oz, and 40oz sizes, there’s one to fit any lifestyle. Its retractable straw lid keeps germs out and makes it easy to toss in your bag without worrying about spills. But to keep your tumbler performing at its best, regular cleaning is key. Whether you're drinking iced coffee, water, or your favorite hydration mix, cleaning your stainless steel tumbler properly helps extend its life and prevent buildup of odors or bacteria.

Here’s a step-by-step guide to cleaning your Ello Oasis Tumbler the right way.

Why You Should Clean Your Stainless Steel Tumbler Regularly

We love stainless steel. It’s durable and helps maintain drink temperature, but it still needs to be cleaned regularly. A regular cleaning routine keeps your Oasis looking and functioning like new while keeping your drinks tasting fresh. And the good news? Cleaning your Ello Oasis water bottle is super easy.

Step-By-Step Cleaning Guide

1. Disassemble All Parts

Start by fully taking apart your Oasis tumbler:

  • Remove the lid from the base

  • Twist the lid dial to open the straw port

  • Pull the straw out completely

Disassembling all components ensures you can clean every surface that comes into contact with your drinks.

2. Clean Using the Right Tools

For best results, we recommend using the Bottle & Straw Cleaning Brush Set. These are specifically made to reach into narrow spaces and tight corners inside the bottle and lid.

  • Use the straw cleaner to scrub inside the straw

  • Use the bottle brush to clean the interior of the stainless steel base and the lid

  • Make sure to scrub around the straw opening, dial mechanism, and gasket area.
    Rinse all parts thoroughly with warm water.

3. Dishwasher Instructions

All components of the Ello Oasis Tumbler are top-rack dishwasher safe. To clean in the dishwasher:

  • Place the bottle base upside down on the top rack

  • Keep the lid open and also face it downward

  • Place the straw in the utensil compartment

Note: If your tumbler has a printed or painted exterior (like our 3D designs), we recommend handwashing the outside to preserve the beauty of the paint.

4. Dry Completely and Reassemble

Allow all parts to air dry fully before putting your tumbler back together. This prevents moisture from getting trapped and reduces the risk of mold.

How Often Should You Clean It?

If you're using your Oasis daily, you should rinse it after each use and do a deeper clean every 1–2 days. Any time you use the tumbler for beverages other than water (like smoothies, iced coffee, or electrolyte drinks) you should clean it thoroughly that same day.

For those using it strictly for water, rinsing daily and deep cleaning twice a week is generally sufficient.

Final Tips

The Ello Oasis Tumbler is designed for performance and ease of use, but like any hydration essential, a little maintenance goes a long way. Following this cleaning routine helps ensure your tumbler stays fresh and ready for whatever your day holds.
