A simple daily and deep-clean routine for your MUD Shaker that stops odors and stains before they start. Includes the whisk ball mistake most people make.

Quick answer

Rinse your MUD Shaker with warm water the moment you finish your shake, then wash it by hand with mild dish soap and a bottle brush within an hour. Once a week, deep clean the bottle, lid, and whisk ball with a baking soda paste or a white vinegar soak. Skip the dishwasher for the bottle and never leave protein residue sitting overnight, because that is what causes both smells and stains.

Why protein residue is the real culprit

MUD\WTR Nourish and similar protein powders leave behind a thin film of protein, fat, and sometimes natural sweeteners. That film is food for odor-causing bacteria. If it dries inside the bottle or under the lid gasket, you get a sour smell that regular rinsing will not fix. The same film bonds to stainless steel and plastic over time and shows up as a cloudy or chalky stain. The fix is not a stronger cleaner. It is removing the film before it sets, which means cleaning soon after every use rather than waiting for a big wash day.

What you need and what to avoid

Keep a soft bottle brush, mild dish soap, warm water, and a clean drying rack. For deep cleans, add baking soda and white vinegar. Avoid abrasive scrubbers, bleach, and heavily scented dish soaps. Abrasives scratch the interior and give residue more places to hide, while bleach can degrade plastic lids and gaskets. Scented soaps can also leave a perfume film that changes the taste of your next shake. If your tap water is very hard, use filtered water for rinsing to reduce mineral spots that look like stains.

How often to clean each part

The bottle and whisk ball need a full wash after every use. The lid and gasket need the same daily wash, but also a weekly deep clean because residue collects in the gasket groove where a brush may not reach. If you use your shaker only for water or plain mushroom coffee, a thorough rinse and air dry may be enough on some days. For anything with protein powder, treat every use as a full wash. A good checkpoint: if you can smell anything at all when you open the dry bottle, it needs a deep clean, not just a rinse.

Your step-by-step MUD Shaker cleaning routine

Step 1: Rinse immediately after your last sip: Fill the bottle halfway with warm water, screw the lid on, and shake for five seconds. Pour it out. This removes most fresh residue before it dries. Common mistake: leaving the shaker on your desk or in a gym bag until later. Dried protein is much harder to remove than wet protein.
Step 2: Disassemble everything: Take off the lid, remove the whisk ball, and pull the gasket out of the lid if it is removable. Residue trapped under the gasket is the number one cause of shaker bottle smells. Checkpoint: if the gasket looks cloudy or feels slimy, it needs a deep clean even if the bottle looks clean.
Step 3: Wash by hand with mild soap and a soft brush: Use warm water, a drop of mild dish soap, and a bottle brush. Scrub the inside walls, the bottom corners, the lid threads, the gasket, and the whisk ball. Pay extra attention to the threads, where residue collects in a thin ring. Common mistake: using a sponge that has touched greasy dishes. It can leave a film that makes your next shake taste off.
Step 4: Rinse until the water runs clear and scent-free: Rinse all parts under warm running water. Rub the inside of the bottle with your finger. If it feels slick or smells like anything other than clean steel, wash it again. Checkpoint: no soap smell, no protein smell, no slippery feel.
Step 5: Air dry fully with the lid off: Place the bottle upside down and the lid and whisk ball separately on a drying rack. Let them air dry completely before you put the lid back on. Trapped moisture is what makes a clean shaker smell musty the next day. Common mistake: screwing the lid on while the bottle is still damp. That seals in moisture and starts the smell cycle again.
Step 6: Deep clean once a week: Make a paste with baking soda and a little water. Rub it on any cloudy or stained areas inside the bottle with your fingers or a soft brush. Let it sit for five minutes, then wash normally. For stubborn odors, soak all parts in equal parts white vinegar and warm water for 30 minutes, then wash and rinse thoroughly. Checkpoint: after deep cleaning, the stainless steel should look evenly bright with no chalky patches.
Step 7: Store it open, not sealed: Between uses, store the bottle with the lid off or loosely resting on top. This lets air circulate and prevents the closed, damp environment where odors start. Next step: if a smell still lingers after a deep clean, replace the gasket if possible or contact MUD\WTR support. Persistent odor usually means residue is trapped in a part you cannot fully reach.

The shaker this routine is built for

MUD Shaker: The MUD Shaker is a 25oz stainless steel shaker with a whisk ball that moves freely inside to break up clumps. Stainless steel resists stains better than plastic, but the whisk ball and lid gasket are where residue hides, so they need the same daily attention as the bottle.
