Reusable coffee cups have become even more popular for the environmentally-conscious consumer. As national governments worldwide try to reduce plastic waste by imposing extra taxes on disposable cups like in the UK (“latte” tax), more and more people are making the switch to reusable coffee cups and travel mugs. Retailers in the UK have confirmed a sharp increase in sales of different kinds of portable mugs, cups and tumblers over the past 2 years. Some coffee shops and cafes are offering discounts to incentivise the use of reusable cups.

Wash your reusable cup as often as you can

Some people recommend washing your portable cup every after use, some say washing it once a day is fine. Regardless, it’s important to know why you should wash your coffee cup regularly.

Your coffee mug could play host to all sorts of bacteria and germs. Particle residue could build up at the bottom of your mug especially if you add sugar and cream to your coffee which is an ideal breeding ground for bacteria and germs. You could end up with an upset stomach or other serious health problems if you drink from a dirty container.

How to wash your reusable coffee cup

Removing dirty particles and gunk from your coffee cup is as easy as tossing it into your dishwasher. Most coffee cup brands are dishwasher-safe but make sure to read your manufacturer’s care instructions.

If your coffee cup is not dishwasher-safe, use hot water, soap and paper towels instead. Hot water helps kill bacteria and germs. Use natural soap like castile soap instead of chemical-laden ones to avoid any unpleasant residue from lingering in your cup. Dry using a paper towel to remove wetness and moisture. Remember that bacteria and mould thrive in damp and moist environments so make sure your coffee cup is dry before putting it away.

You could also do a weekly thoroughly cleaning of your reusable coffee cup to get rid of stains. A mixture of baking soda and vinegar is highly recommended because both are known as excellent cleaning agents and non-abrasive. Use a soft brush to clean hard to reach areas especially the mouthpiece if your reusable cup has a leak proof lid

Additional information

Choose a stainless steel coffee mug if you do not want to clean it every after use. Stainless steel is relatively easier to clean and most resistant to bacterial growth. Also, buy a mug that does not have too many removable parts because while they add style and personality to your cup, they make cleaning your mug difficult and inconvenient.

Never use shared sponges especially if you work in an office. Communal sponges hold on to bacteria and germs so you’re better off using your own hands, they’re cleaner.

With proper and regular care, you can keep your portable cup reusable for many years. You would not have to buy a replacement every year which could result in long term savings for you.

Also, coffee shops have the right to refuse to fill dirty cups so save yourself from potential embarrassment and health troubles by cleaning your reusable coffee cup regularly.
