Most people forget to clean this part of their travel mug

Learn how to keep your stainless steel travel coffee mug fresh and odor-free.

Your trusty travel coffee mug has been with you through countless morning commutes, afternoon carpools, and weekend road trips. But if you're like me, that tumbler has probably spent a few too many days forgotten in your car, developing that less-than-pleasant aroma and stains, too, that make you question your life choices. The good news? Cleaning your stainless-steel travel mug doesn't have to be a chore, and with the right approach, you can keep it looking and smelling fresh.

How Often to Wash

The secret to a pristine travel mug isn't complicated cleaning solutions or special tools—it's consistency. "Clean it regularly!" emphasizes Contorno. "The best way to keep your stainless-steel coffee mug looking and smelling fresh is to wash it after every use—don't let it sit in your car for a few days (we've all been there)." While we're all guilty of leaving our mugs in the car until they become science experiments, establishing a simple routine of washing after each use prevents the buildup of oils, bacteria, and that stubborn coffee residue. 

Dishwashing vs. Hand Washing

When it comes to cleaning methods, you have options, and there’s not a rule that says handwashing versus dishwashing is better. Instead, turn to the labeling. While many stainless-steel mugs can handle the dishwasher, some brands recommend hand washing to preserve the exterior finish and any decorative elements. If your mug is dishwasher safe, do what works best for your schedule. For Reduce products, the answer's easy: their mugs are top-rack dishwasher safe, so toss them in and let the machine do the work. 

Best Cleaning Methods

Choosing the correct cleaning products is crucial for maintaining your mug's integrity and appearance. For hand washing, Contorno recommends using mild dish soap and a non-abrasive sponge or soft-bristle brush. If you're using the dishwasher, your preferred dishwasher detergent works perfectly. 

While stainless steel is durable, harsh chemicals and abrasive tools can compromise its protective coating, leading to discoloration and potential rust issues down the road. "Stay away from bleach, cleaners with chlorine, and any abrasive scrubbing tools like steel wool or rough sponges," warns Contorno. "These can damage the stainless-steel surface and cause rust over time." 

Tackling Stubborn Stains and Odors

Even with regular cleaning, sometimes your travel mug needs a little extra attention. For those stubborn stains or rust spots that regular washing can't handle, Contorno suggests two effective home remedies.

The first option is a baking soda paste, which can lift stains without damaging the stainless-steel surface. "Just mix warm water with baking soda, then gently scrub with a soft sponge or soft-bristle brush,” says Contorno. For particularly stubborn odors or stains, try a vinegar soak.  "Fill your mug with equal parts vinegar and warm water, let it sit for 5-10 minutes, then wash as usual with mild soap and soft sponge or soft-bristle brush." The acidity in vinegar helps break down mineral deposits and naturally neutralizes odors.

The Bottom Line

Keeping your travel coffee mug clean doesn't require expensive products or complicated procedures. The key is regular maintenance. With these expert tips, you can maintain that just-bought freshness and ensure every sip of your favorite brew tastes exactly as it should.
