Learn the simple steps to clean and maintain the bamboo cap on your 27oz Reflect bottle without damaging the natural materials.
Quick Answer
Hand-wash the bamboo cap with mild soap and warm water, then air-dry it completely before reattaching to your 27oz Reflect bottle.
Why Bamboo Needs Special Care
The bamboo cap on your 27oz Reflect bottle is a natural material, not plastic. It can warp, crack, or develop mold if soaked or run through a dishwasher. The cap's bamboo exterior and stainless steel interior mean water can get trapped between layers if not dried properly.
Step-by-Step Cleaning Guide
- Remove the Cap and Rinse: Unscrew the bamboo cap from the bottle. Rinse the cap under warm running water to remove loose debris. Avoid hot water, which can dry out the bamboo. Checkpoint: Do not submerge the cap in water; hold it under the stream only.
- Wash with Mild Soap: Apply a drop of mild dish soap to a soft cloth or sponge. Gently wipe the bamboo exterior and the stainless steel interior. Do not use abrasive scrubbers or bleach-based cleaners. Common mistake: Scrubbing with a stiff brush can scratch the bamboo finish.
- Rinse and Dry Immediately: Rinse the cap briefly under warm water to remove soap. Shake off excess water, then dry the cap thoroughly with a clean towel. Pay extra attention to the gap between the bamboo and the steel rim. Checkpoint: Let the cap air-dry completely (cap off the bottle) for at least an hour before reassembling.
