Reusable Cup and Bottle Care: How to Clean Lids, Straws and Sleeves

Quick answer

Rinse your frank green bottle and lid with warm water immediately after each use, then deep clean weekly with mild dish soap and a bottle brush. For flip straw lids, disassemble the silicone mouthpiece and straw, and scrub with a straw brush. Cactus leather sleeves should be wiped with a damp cloth and air-dried—never soaked or put in the dishwasher.

Your reusable cup or bottle works hard every day, so a little care keeps it tasting fresh and looking good. Whether you own a ceramic-lined bottle, a flip straw lid, or a cactus leather sleeve, the right cleaning routine prevents odors, stains, and premature wear.

This guide walks you through each step, from daily rinses to deep cleans, with specific advice for frank green accessories. You'll also learn the common mistakes that can damage lids, straws, and sleeves—and how to avoid them.

Daily rinse: the 30-second habit that prevents buildup

After finishing your drink, rinse the bottle and lid with warm water. This removes residual liquid before it dries and becomes sticky or smelly. For the bottle, fill halfway, swirl, and pour out. For the lid, run water through the mouthpiece and straw opening.

If you used a flip straw lid, flip the mouthpiece up and rinse underneath—sugary drinks can leave residue that attracts bacteria. A quick rinse now saves you scrubbing later. Set the parts on a drying rack to air dry completely before reassembling.

• Never leave liquid sitting in your bottle overnight; it speeds up odor and staining.
• Rinse the straw separately by running water through it.

Weekly deep clean: soap, brush, and warm water

Once a week, disassemble your bottle completely. Wash the bottle base, lid hull, silicone seals, and straw in warm water with mild dish soap. Use a bottle brush to reach the bottom and sides; for ceramic-lined bottles, a soft brush is best to avoid scratching the lining.

For the lid, pay attention to the mouthpiece and any crevices. A small straw brush works well for the flip straw lid's internal tube. Rinse everything thoroughly—soap residue can leave a taste. Let all parts air dry fully before putting them back together.

• Use a dedicated bottle brush; sponges may not reach deep corners.
• Avoid abrasive cleaners or scouring pads that can scratch ceramic or stainless steel.

How to clean a flip straw lid without damaging it

The flip straw lid is designed for one-handed hydration, but its moving parts need gentle handling. Start by flipping the mouthpiece open. If your lid has a removable silicone mouthpiece, gently pull it off. Soak the lid hull and mouthpiece in warm soapy water for a few minutes.

Use a straw brush to scrub inside the straw and the mouthpiece. For the lid hull, a soft bottle brush or cloth works. Rinse well and let dry completely before reassembling. Never put the lid in the dishwasher unless the manufacturer explicitly says it's dishwasher safe—high heat can warp seals.

• Check the silicone mouthpiece for wear; replace if it becomes loose or cracked.
• Don't use boiling water on plastic lid components; it can deform them.

Reusable straw cleaning: keep the inside spotless

Straws are often the dirtiest part because liquid sits inside them. For stainless steel straws, use a straw brush with soapy water and push it through from end to end. Rinse and repeat until the water runs clear. For silicone straws, flex them to check for cracks where residue can hide.

If your straw came with a strap, wash the strap by hand with soap and water, then air dry. Avoid putting straws in the dishwasher if they're made of silicone or have a coated finish—heat can degrade them over time.

• Store straws upright in a clean cup to let them dry completely.
• Replace straws if they develop a persistent smell or visible buildup.

Cactus leather sleeve care: wipe, don't soak

The Cactus Leather Sleeve adds grip and style, but it needs different care than the bottle. Wipe it with a damp cloth and mild soap if needed, then dry immediately with a soft towel. Never submerge it in water or put it in the washing machine—moisture can damage the material.

For everyday maintenance, a quick wipe is enough. Avoid leaving the sleeve in direct sunlight for long periods, as it may fade. If the sleeve gets stained, dab gently with a damp cloth; scrubbing can roughen the surface.

• Remove the sleeve before washing the bottle to avoid accidental soaking.
• Air dry the sleeve away from direct heat.

Button lids have a push-button mechanism that can trap liquid. To clean, press the button to open the mouthpiece, then rinse thoroughly. If possible, remove the silicone seal and wash it separately. Use a small brush to clean around the button and any crevices.

If the button feels sticky, a diluted vinegar solution can help dissolve residue. Rinse well afterward. Never force the mechanism or use sharp tools—it can break the lid.

• Test the button after cleaning to ensure it moves freely.
• If the lid remains sticky, contact customer support for advice.

Your 5-step cleaning routine

1. Disassemble: Take apart the bottle, lid, straw, and sleeve. Remove silicone seals and mouthpieces where possible. Check for small parts that could be lost down the drain.
2. Pre-rinse: Rinse all components with warm water to remove loose debris and sugary residue. Don't skip this—it makes washing easier.
3. Wash: Use mild dish soap and a bottle brush for the bottle, a straw brush for straws, and a soft cloth for the sleeve. Avoid abrasive cleaners that can scratch surfaces.
4. Rinse and dry: Rinse everything thoroughly and air dry on a rack. Ensure all parts are completely dry before reassembling. Moisture trapped inside can cause mold.
5. Reassemble and test: Put the lid and straw back together, and check that the button or flip mechanism works smoothly. If anything feels stiff, re-clean that part.

Product facts that affect cleaning

• 68oz Bottle with Flip Straw Lid: Triple-wall insulated, ceramic lined for pure taste, made from >90% recycled premium stainless steel. The ceramic lining is scratch-resistant but should be cleaned with a soft brush to maintain its non-stick properties; the stainless steel body is durable but can dent if dropped.
