Learn how to properly clean your Corkcicle Keep Fresh Canister. Step-by-step guide to maintain its airtight seal and keep coffee beans fresh longer.
Quick answer
Hand wash your Keep Fresh Canister with mild soap and warm water, then air dry completely before reassembling the airtight lid.
Why hand washing is better than the dishwasher
The Keep Fresh Canister’s airtight seal relies on a silicone gasket and an internal compressor. Dishwasher heat and high-pressure jets can degrade the gasket over time, reducing the seal’s effectiveness. Hand washing keeps the seal intact and extends the canister’s life.
Avoiding trapped moisture and odors
Coffee beans are porous and absorb moisture and odors. If the canister is not fully dry before you add fresh beans, the seal can trap humidity, leading to stale-tasting coffee. Always dry the canister and lid separately to prevent this.
Step-by-step cleaning process
- 1. Empty and disassemble: Remove all coffee beans from the canister. Take off the lid and separate the internal compressor if it is removable. Set aside the silicone gasket if it comes out easily. Check the gasket for cracks or wear each time you remove it.
- 2. Hand wash with mild soap: Wash the glass body, lid, and gasket with warm water and a drop of mild dish soap. Use a soft sponge or cloth. Avoid abrasive scrubbers that could scratch the glass or damage the seal. Do not use bleach or harsh chemicals; they can break down the silicone gasket.
- 3. Rinse and air dry completely: Rinse all parts thoroughly with clean water. Place them upside down on a drying rack. Let every piece dry completely—at least 2 hours—before reassembling. Any remaining moisture can affect coffee freshness. If you are in a hurry, pat the parts dry with a lint-free towel, then let them sit open for 15 minutes.
- 4. Reassemble and test the seal: Once everything is dry, reattach the gasket and compressor, and screw the lid back on. Press the top to check that the internal compressor moves freely and the lid seals tightly. If the lid does not press down smoothly, the gasket may be misaligned; remove and reseat it.
What you are cleaning
- Keep Fresh Canister: Designed with an airtight seal, this canister features an internal compressor to eliminate air and light, preventing oxidation, which means coffee beans stay fresher, for weeks longer. The internal compressor and seal are delicate parts; proper cleaning protects them so your beans stay fresh as long as possible.
