Travel Mug Care: Keep Your I'm Not Ovary-Acting Mug Fresh

Quick answer

Rinse your I'm Not Ovary-Acting Travel Mug with warm water as soon as you finish drinking, wash the acrylic lid by hand with mild soap, and deep clean the stainless-steel body once a week with baking soda. Never put the lid in the dishwasher or leave coffee or tea sitting in the mug overnight—that is what causes stubborn odors and stains.

What makes this mug different to clean

The I'm Not Ovary-Acting Travel Mug is a 20oz double-wall stainless steel mug with a non-skid foam base and an acrylic lid with a thumb-slide closure. That mix of materials is why a single cleaning method does not fit all parts: stainless steel tolerates baking soda and gentle scrubbing, the foam base does not want to soak, and the acrylic lid can cloud or crack if it goes through a hot dishwasher cycle. Treat the three parts separately and the mug stays fresh without damage.

One honest limitation: the catalog does not list the lid as dishwasher-safe, so hand-washing is the safe assumption. If you ever want to confirm, check the packaging or the product page before running it through a machine.

Daily rinse and weekly deep clean

For everyday use, empty the mug and rinse it with warm water within an hour of finishing your drink. A quick rinse stops milk, tea, or coffee residue from drying into the steel. Once a week—or sooner if you use it daily for coffee—deep clean the body with a paste of baking soda and water, scrub with a soft bottle brush, and rinse thoroughly. This lifts the tannin film that makes stainless steel look dull and hold onto old flavors.

Skip abrasive scouring pads and bleach-based cleaners on the steel. They scratch the interior finish, and scratched stainless steel traps odor more easily over time.

Lid cleaning without cracking the acrylic

The acrylic lid with thumb-slide closure collects residue in the slide track and the gasket area, which is where most travel mug odors actually start. Remove the lid, open the slide, and wash it by hand in warm water with a drop of mild dish soap. Use a small soft brush or a cotton swab to work along the slide channel, then rinse and air dry fully with the slide open.

Avoid soaking the lid in hot water for long periods and never boil it. Acrylic can warp or develop fine cracks, and a cracked lid leaks and traps moisture. If the slide feels sticky after cleaning, rinse again rather than forcing it—residue, not the mechanism, is usually the cause.

Odor removal when a rinse is not enough

If the mug still smells like yesterday's coffee after a normal wash, fill it with warm water and one to two tablespoons of baking soda, let it sit for 30 minutes, then scrub and rinse. For a lingering sour milk smell, a 50/50 mix of warm water and white vinegar left for 15 minutes usually works. Rinse thoroughly afterward so your next drink does not taste like vinegar.

Do not seal a damp mug with the lid on. Trapped moisture between the lid and the steel is the fastest way to grow a musty smell. Store the mug open and upside down so air reaches the inside.

Protecting the foam base and finish

The non-skid foam base keeps the mug steady, but foam degrades if it stays wet. After washing, dry the base with a towel instead of leaving the mug to drip dry on a rack, and never submerge the mug in a sink full of water. Hand wash the body rather than using a dishwasher, which exposes the foam and the exterior print to heat and detergent over repeated cycles.

For the exterior, wipe with a damp cloth and dry immediately. This keeps the printed message sharp and avoids water spots on the stainless steel.

Your five-step travel mug care routine

1. Rinse right after use: Empty the mug and rinse with warm water within an hour of finishing your drink. If you had milk or a sweetened drink, add a drop of mild soap and rinse again. Checkpoint: no visible residue or film left on the steel.
2. Hand wash the lid: Remove the acrylic lid, open the thumb-slide, and wash by hand with warm water and mild soap. Use a soft brush or cotton swab in the slide track and gasket area, then rinse. Common mistake: soaking the lid in hot water or putting it in the dishwasher, which can warp or cloud the acrylic.
3. Deep clean the body weekly: Make a paste of baking soda and water, scrub the inside with a soft bottle brush, and rinse until the water runs clear. Use this step more often if you drink coffee or tea daily. Common mistake: using abrasive pads or bleach, which scratch the stainless steel and make future odors harder to remove.
4. Treat odors at the source: For coffee or tea smell, soak with warm water and one to two tablespoons of baking soda for 30 minutes. For sour milk smell, use a 50/50 warm water and white vinegar soak for 15 minutes, then rinse thoroughly. Checkpoint: the mug smells neutral after rinsing, not like vinegar or old coffee.
5. Dry fully and store open: Towel-dry the foam base and the exterior, then let the mug and lid air dry completely with the lid off and the slide open. Store upside down so air circulates inside. Common mistake: sealing a damp mug with the lid on, which traps moisture and creates a musty smell.
