One of the most common questions we get at ReBOTTLE is: "How do I clean the cork?" or "Will water ruin the exterior?"
We have good news: Maintaining your ReBOTTLE is actually easier than you think. Because we use high-grade stainless steel and the cork is naturally water-resistant and antibacterial, your ReBOTTLE is designed for everyday use.
However, like any premium product made from natural materials, a little love goes a long way. Here is everything you need to know to keep your bottle fresh for years to come.
The Golden Rule: Hand Wash Only
Before we dive into the tips, there is one major rule to remember:
While the food-grade stainless steel interior is durable, the high heat and aggressive water pressure of a dishwasher can damage the natural cork coating over time. Hand washing is gentle, quick, and effective.
Step 1: Cleaning the Inside (Stainless Steel)
The interior of your bottle is made of food-grade stainless steel, which doesn't retain flavors. For daily cleaning:
- Warm Soapy Water: Simply fill the bottle with warm water and a drop of mild dish soap. shake it well, rinse, and let it dry.
- Deep Clean (Eco-Friendly Way): Once in a while, if you drink coffee or smoothies, you might want a deeper clean. Mix a teaspoon of Baking Soda with warm water inside the bottle. Let it sit for an hour (or overnight) and rinse. This neutralizes any lingering odors naturally.
Step 2: Caring for the Outside (The Cork)
Many people assume cork is fragile like paper, but remember—this material protects trees from harsh weather in the forest! It is naturally water-repellent and antimicrobial.
To clean the cork exterior:
- Wipe it down: Use a soft cloth dampened with warm water and mild soap. Gently wipe the surface to remove dirt or oils from your hands.
- Air dry: After washing, let your bottle air dry with the cap off.
- Avoid harsh chemicals: Never use bleach or abrasive scrubbers on the cork, as this can damage the natural finish.
Embracing the "Patina"
ReBOTTLE is a natural product. Over time, just like high-quality leather, cork may slightly change its color or texture as it interacts with the oils in your hands and the environment. This isn't a defect; it’s called Patina. It means your bottle is aging gracefully and telling the story of your adventures. It makes your specific bottle truly one of a kind.
