🧼 Step-by-Step Cleaning Instructions

1

Disassemble Your Tumbler

Remove the lid, gasket/rubber seal, straw, and any other removable parts from your LAMOSE tumbler. This ensures every component gets thoroughly cleaned. Keep track of small pieces—lay them out on a clean towel.

2

Initial Rinse

Rinse the tumbler and all components with warm water to remove loose debris, residue, and leftover beverage particles. This prepares surfaces for deep cleaning.

3

Create Cleaning Solution

Mix 2 tablespoons of baking soda with 2 cups of warm water inside the tumbler. Swirl to dissolve. For extra cleaning power, add 3-4 drops of mild dish soap. This natural solution breaks down oils, odors, and residue without harsh chemicals.

4

Scrub the Interior

Using a bottle brush or long-handled sponge, scrub the entire interior surface, paying special attention to the bottom and corners where residue accumulates. Use circular motions and moderate pressure. Don't forget to scrub the threads at the top where the lid attaches.

5

Clean Lid Components

Soak the lid, gasket, and straw in a bowl with warm soapy water for 5 minutes. Use a small brush to clean crevices, the gasket groove, and inside the straw. These areas harbor the most bacteria, so be thorough.

6

Rinse Thoroughly

Rinse all components under warm running water until no soap residue or baking soda remains. This is crucial—leftover cleaning agents can affect the taste of your beverages and potentially damage the insulation seal over time.

7

Dry Completely

Air dry all components upside down on a clean drying rack or towel. Ensure everything is completely dry before reassembling to prevent mold and mildew growth. This may take 2-4 hours. For faster drying, wipe with a microfiber cloth.

💡
Pro Tip:

Never reassemble your LAMOSE tumbler while components are still damp. Trapped moisture between the lid seal and tumbler creates the perfect environment for bacterial growth and unpleasant odors.

🔥 Deep Cleaning for Stubborn Issues

Method 1: Vinegar Soak (For Odors & Mineral Deposits)

  1. Fill tumbler with equal parts white vinegar and warm water (1:1 ratio)
  2. Let soak for 2-3 hours or overnight for severe odors
  3. Empty and scrub with baking soda paste (3 tbsp baking soda + 1 tbsp water)
  4. Rinse thoroughly—vinegar smell will dissipate once dry
  5. Air dry completely
Best for: Coffee stains, tea tannins, lingering smoothie smells, hard water buildup

Method 2: Tablet Clean (For Heavy Buildup)

  1. Fill tumbler with warm (not hot) water
  2. Drop in 1-2 denture cleaning tablets or bottle cleaning tablets
  3. Let fizz and soak for 30-60 minutes
  4. Scrub lightly with bottle brush
  5. Rinse thoroughly multiple times
Best for: Protein residue, stubborn stains, deep sanitization

Method 3: Ice + Salt Scrub (For Stains)

  1. Add 1/4 cup crushed ice to tumbler
  2. Add 2 tablespoons coarse salt (kosher or sea salt)
  3. Add 1/4 cup warm water

Pro Tip:

LAMOSE tumblers feature double-wall vacuum insulation. Never submerge the entire tumbler or put it in the dishwasher—the extreme heat and moisture can compromise the vacuum seal, reducing insulation performance permanently.

❓ Frequently Asked Questions

Can I put my LAMOSE insulated tumbler in the dishwasher? +
No, never put insulated tumblers in the dishwasher. The high heat and harsh detergents can damage the vacuum seal between the double walls, compromising insulation performance. The intense water pressure can also force moisture between the walls. Always hand wash with warm water and mild soap for longevity.
Why does my tumbler smell even after washing? +
Persistent odors usually come from bacteria trapped in the lid gasket or from oils/proteins that regular soap can't break down. Try the vinegar soak method (equal parts vinegar and water for 2-3 hours), then scrub with baking soda paste. Also check the rubber gasket—remove it completely and scrub both sides, as bacteria hide in the groove underneath.
How do I remove coffee or tea stains from the interior? +
Make a paste with 3 tablespoons baking soda and 1 tablespoon water. Apply to stained areas and let sit for 15-20 minutes. Scrub with a bottle brush, then rinse. For stubborn stains, try the ice + salt scrub method or use denture cleaning tablets. White vinegar also helps dissolve tannin stains—soak overnight for best results.
