A practical, step-by-step routine to remove coffee stains and lingering odours from your Huskee cup, plus the mistakes that make both worse.
Quick answer
To remove odour and stains from a Huskee cup, start with a thorough wash using hot water and dish soap, then deep clean with a baking soda paste for stains or a vinegar soak for smells. Rinse completely and dry upside down. Repeat the deep clean weekly if you use the cup daily.
Why Huskee cups hold onto coffee oils and smells
Huskee cups are made from a composite material that includes recycled coffee husk. While this gives the cup its distinctive look and feel, the surface can be slightly more porous than glazed ceramic or stainless steel. Coffee oils and pigments can settle into those microscopic crevices over time, especially if you leave coffee sitting in the cup for hours or skip a full wash after each use. That buildup is what causes both the dull brown staining and the stale, sour smell that lingers even after a normal rinse.
Daily habits that prevent odour and stains
The easiest way to avoid deep cleaning is to never let residue dry inside the cup. Rinse with hot water immediately after you finish your drink, then wash with dish soap and a soft bottle brush before the cup goes back on the shelf. If you can't wash it right away, fill it with warm water and a drop of soap so the coffee doesn't harden. Avoid leaving milk-based drinks in the cup for more than an hour, as dairy proteins cling stubbornly and are a common source of sour smells.
What you'll need for the deep clean
You don't need specialised cleaners. A mild dish soap, baking soda, white vinegar, a soft bottle brush, and a clean cloth are enough. Avoid abrasive scouring pads, bleach-based cleaners, and harsh solvents, which can scratch the surface or leave behind chemical residues that affect taste. If you have a Universal Lid 4-Pack, remove the lid and wash it separately so you can reach the seal and any grooves where odours hide.
Step-by-step deep clean for odour and stains
- 1. Rinse and pre-wash with hot soapy water: Fill the cup with hot water and a squirt of mild dish soap. Use a soft bottle brush to scrub the entire interior, including the bottom corners and the rim. Pay attention to the area just below the rim where coffee oils tend to collect. Checkpoint: if the water runs clear and no oily film remains, you can skip straight to drying for a light clean.
- 2. Make a baking soda paste for stains: Mix three parts baking soda with one part water to form a thick paste. Apply it to stained areas with your finger or a soft cloth. Let it sit for 10–15 minutes, then scrub gently with the brush. Baking soda is mildly abrasive and lifts pigment without scratching. Common mistake: using a scouring pad or steel wool, which can scratch the surface and create new places for stains to settle.
- 3. Soak with white vinegar for odours: If the smell persists after the baking soda treatment, fill the cup with equal parts white vinegar and warm water. Let it soak for 30 minutes to an hour. Vinegar neutralises the alkaline compounds in coffee oils that cause stale smells. Checkpoint: smell the cup after soaking. If a sour note remains, repeat the vinegar soak once more before trying anything stronger.
- 4. Scrub the lid and seal separately: Remove the lid and its silicone seal if it has one. Wash both with hot soapy water, using a small brush to get into the groove where the seal sits. Odour often hides there because liquid gets trapped and doesn't rinse away. Common mistake: ignoring the lid. A clean cup with a smelly lid will still make your coffee taste off.
- 5. Rinse thoroughly and dry upside down: Rinse the cup and lid under running water until no soap or vinegar smell remains. Shake out excess water and place the cup upside down on a drying rack so air can circulate inside. Let it dry completely before storing. Checkpoint: if you can still smell vinegar after drying, give it one more hot water rinse. Trapped moisture is a common cause of musty odours.
- 6. Repeat weekly for daily use: If you use your Huskee cup every day, do the full deep clean once a week. On other days, stick to the hot soapy wash and immediate rinse. This schedule keeps stains from setting and stops odours before they start. Next step: if staining returns quickly, check whether you're leaving coffee in the cup for long periods and adjust your routine.
Products that work with this routine
- 12oz HuskeeRenew 4-Pack: The 12oz HuskeeRenew 4-Pack includes cups and lids designed for everyday use. Having multiple cups means you can rotate them and always have a clean one while another dries, making the daily rinse habit easier to keep.
- 16oz HuskeeRenew: The 16oz HuskeeRenew is a single cup and lid option. If you mostly drink larger coffees, this size reduces the chance of leftover coffee sitting in the cup, which is a common cause of odour.
- Universal Lid 4-Pack: The Universal Lid 4-Pack is designed to fit HuskeeCups. Extra lids let you swap out a lid that has picked up a smell while the other is being washed, so you never skip a deep clean.
