Color changing cups are a fun and engaging way to encourage kids to stay hydrated. But to keep the color-changing magic working, proper care is essential. In this guide, we'll walk you through the best practices for cleaning Ello color changing cups, so they stay vibrant and functional for years to come.
Ello's color changing cups are designed with special thermochromic materials that react to temperature. Whether you have the Ellies Kids Water Bottle - 16oz, Tritan Plastic or the Oasis Kids Stainless Steel Tumbler, understanding how to clean them correctly will preserve their unique feature and keep them safe for daily use.

Why Proper Cleaning Matters for Color Changing Cups
Color changing cups rely on a special pigment that is sensitive to heat and chemicals. Harsh detergents, high temperatures, or abrasive scrubbing can damage this pigment, causing the color change to fade or stop working altogether. By following the right cleaning routine, you can extend the life of your Ello color changing cups and keep them looking and performing their best.
Additionally, proper cleaning ensures that no residue or bacteria builds up, which is especially important for kids' cups that are used daily. A clean cup not only looks better but also provides a healthier drinking experience.
- Avoid using bleach or chlorine-based cleaners.
- Do not soak in very hot water for extended periods.
- Always check the care instructions that came with your cup.
Step-by-Step Hand Washing Instructions
The safest and most recommended method for cleaning Ello color changing cups is hand washing. Start by rinsing the cup with warm (not hot) water to remove any loose particles. Then, use a mild dish soap and a soft sponge or cloth to gently clean the inside and outside of the cup. Pay special attention to the lid and any straw components, as these can harbor bacteria.
For stubborn stains or odors, you can create a paste with baking soda and water and gently scrub the affected areas. Rinse thoroughly with warm water and allow the cup to air dry completely before storing. Avoid using abrasive scrubbers or steel wool, as they can scratch the surface and damage the color-changing layer.
- Use a bottle brush to reach the bottom of the cup.
- For lids with gaskets, remove them and clean separately.
- Rinse all soap residue thoroughly to avoid affecting the color change.
Dishwasher Safety: What You Need to Know
Many Ello cups are labeled dishwasher safe, but the high heat and harsh detergents in dishwashers can accelerate the fading of the color-changing effect. To preserve the magic, we recommend hand washing your Ello color changing cups, even if they are technically dishwasher safe. If you do choose to use the dishwasher, place the cup on the top rack and select a gentle cycle with low heat.
Also, avoid using the heated dry cycle, as the prolonged high temperature can damage the thermochromic pigment. Over time, even occasional dishwasher use can reduce the vibrancy of the color change, so hand washing is the best way to ensure long-term performance.
- If using a dishwasher, skip the heated dry cycle.
- Consider using a mild detergent without chlorine bleach.
- Remove any silicone or rubber parts that may not be dishwasher safe.
Common Mistakes to Avoid
One of the most common mistakes is using boiling water or very hot liquids to clean the cup. This can cause the color-changing pigment to break down permanently. Similarly, leaving the cup in direct sunlight for extended periods can fade the colors over time. Always store your Ello color changing cups in a cool, dry place away from direct sunlight.
Another mistake is using abrasive cleaning tools, which can scratch the surface and make the color change appear uneven. Stick to soft cloths and gentle brushes. Additionally, avoid using strong chemical cleaners like bleach or ammonia, as they can react with the thermochromic materials and ruin the effect.
- Never use metal scrubbers or abrasive pads.
- Do not leave the cup soaking in soapy water overnight.
- Keep the cup away from extreme temperatures, both hot and cold.
Caring for Different Types of Ello Color Changing Cups
Ello offers a variety of color changing cups, including the Ellies Kids Water Bottle - 16oz, Tritan Plastic and the Oasis Kids Stainless Steel Tumbler. While the cleaning steps are largely the same, there are a few differences to keep in mind. For Tritan plastic cups, avoid using very hot water as it can warp the plastic. For stainless steel tumblers, be extra careful not to drop them, as dents can affect the color-changing layer.
Additionally, if your cup has a straw, make sure to clean the straw thoroughly using a small brush. Some Ello cups come with replacement lids and straws, so you can easily swap out parts if they become worn or damaged. Regular maintenance will keep your cups looking new and functioning properly.
- For stainless steel, avoid abrasive cleaners that can scratch the finish.
- For plastic cups, check for any cracks or damage that could harbor bacteria.
- Replace any damaged parts promptly to maintain hygiene.
Cleaning your Ello color changing cups doesn't have to be complicated. By hand washing with mild soap, avoiding harsh chemicals and high heat, and following the tips in this guide, you can keep the color-changing magic alive for many sips to come. Remember, a little extra care goes a long way in preserving the fun and functionality of your Ello cups.
