Quick Answer
To keep your Fenix insulated cup performing at its best, hand wash it with mild soap and warm water, avoid abrasive tools, and never put it in the dishwasher or microwave.
Why Care Matters for Your Fenix Insulated Cup
The Fenix Stainless Steel Insulated Cup uses double-wall 18/8 stainless steel and copper vacuum insulation to keep drinks cold or hot for hours. Proper care preserves that insulation and the cup's durability.
The copper plating on the inner wall is what makes the temperature difference of up to 9°F (5°C) possible. Harsh cleaning methods can damage that layer, so gentle handling is key.
Trade-Offs: Hand Washing vs. Dishwasher
While it's tempting to toss the cup in the dishwasher, the high heat and strong detergents can degrade the copper vacuum insulation over time. Hand washing is safer and takes only a minute.
Similarly, the microwave is a no-go: the stainless steel body will block the waves and can damage the cup or your appliance. Stick to pre-heated or pre-chilled liquids instead.
Step-by-Step Care Routine
- Rinse immediately after use: Empty the cup and rinse it with warm water right after finishing your drink. This prevents residue from drying and making cleaning harder. Don't let coffee or tea sit for hours; it can stain the interior.
- Hand wash with mild soap: Use a soft sponge and a drop of mild dish soap with warm water. Gently scrub the inside and outside, then rinse thoroughly. Avoid steel wool or abrasive pads; they can scratch the stainless steel and damage the copper layer.
- Dry upside down: Shake off excess water and place the cup upside down on a dish rack to air dry. This prevents water spots and keeps the interior fresh. Make sure the cup is completely dry before storing to avoid odors.
- Deep clean occasionally: Once a week, fill the cup with warm water and a teaspoon of baking soda. Let it sit for 15 minutes, then scrub gently and rinse well. Baking soda removes residual odors without harsh chemicals.
- Store with the lid off: Keep the cup with the lid off when not in use to allow air circulation. This prevents moisture buildup and keeps the seal fresh. If you store it with the lid on, make sure it's bone dry to avoid mildew.
