In this guide, we'll walk you through the best practices for using, cleaning, and maintaining your Brew Cork QuickSip, so you can enjoy every sip worry-free.

Do: Use the Right Cleaning Methods
Keeping your Brew Cork QuickSip clean is crucial for both hygiene and longevity. The glass body is dishwasher safe, but the cork sleeve and lid require a bit more care. To clean the glass, you can place it in the dishwasher on a gentle cycle, but hand washing with warm, soapy water is always a safe bet. For the cork sleeve, avoid submerging it in water for extended periods, as this can cause the cork to swell or crack. Instead, wipe it with a damp cloth and mild detergent, then let it air dry completely.
The lid, especially the QuickSip mechanism, should be cleaned regularly to prevent coffee or tea residue from building up. Disassemble the lid and rinse each part under warm water, using a soft brush to remove any stubborn residue. Avoid using abrasive scrubbers or harsh chemicals, as they can damage the silicone and plastic components. By following these cleaning do's, you'll keep your cup fresh and functional for years.
- Hand wash the cork sleeve with a damp cloth, never soak it.
- Use a bottle brush to clean the inside of the glass if you can't remove residue.
- Always dry the cork sleeve completely before storing the cup.
Don't: Expose Your Cup to Extreme Temperatures
While the glass body of the Brew Cork QuickSip is designed to handle hot and cold beverages, it's not invincible. Avoid subjecting the cup to sudden temperature changes, such as pouring boiling water into a cold glass or placing the cup in the freezer. These rapid shifts can cause the glass to crack or shatter. Always preheat or pre-cool the cup with a small amount of water before adding your beverage if the temperature difference is significant.
Similarly, never microwave the Brew Cork QuickSip. The cork sleeve and the glass are not microwave-safe, and doing so could damage the cup or cause injury. Instead, heat your beverage in a separate container and then pour it into the cup. By respecting the temperature limits of your cup, you'll ensure its durability and safety.
- Avoid pouring boiling water directly into a cold cup.
- Do not place the cup in the freezer or microwave.
- Let hot beverages cool slightly before pouring them in.
Do: Handle the Cork Sleeve with Care
The cork sleeve is a signature feature of the Brew Cork QuickSip, providing insulation and grip. However, cork is a natural material that requires gentle handling. Avoid dropping your cup, as the cork can dent or tear upon impact. When placing the cup on surfaces, do so gently to prevent scuffs. If the cork gets stained, you can lightly sand it with fine-grit sandpaper to restore its appearance, but be careful not to over-sand.
To maintain the cork's natural oils and prevent it from drying out, you can occasionally rub a small amount of cork conditioner or mineral oil into the surface. This will keep the cork supple and prevent cracking. Always allow the conditioner to absorb fully before using the cup. With proper care, your cork sleeve will age beautifully and provide excellent insulation for years.
- Use a gentle touch when setting the cup down to avoid dents.
- Apply cork conditioner monthly to keep the cork hydrated.
- Sand minor scratches with fine-grit paper if needed.
Don't: Ignore the Lid's Seal and Hinge
The QuickSip lid is designed for convenience, but it requires regular attention to maintain its seal. Over time, the silicone gasket may become loose or worn, leading to leaks. Inspect the lid regularly and replace the gasket if you notice any damage. Also, ensure the hinge is not clogged with debris, which can prevent the lid from opening and closing smoothly. A quick rinse under warm water usually clears any blockages.
When closing the lid, make sure it clicks securely into place. If the lid feels loose, check the alignment and tighten any screws if applicable. Avoid twisting the lid excessively, as this can strip the threads. By keeping the lid in good condition, you'll prevent spills and maintain the cup's airtight seal, keeping your beverages at the right temperature for longer.
- Check the silicone gasket for wear every few months.
- Clean the hinge area with a toothpick to remove debris.
- Replace the gasket if leaks occur.
Do: Use Your Cup for Its Intended Purpose
The Brew Cork QuickSip is perfect for hot coffee, tea, and cold beverages. However, it's not designed for carbonated drinks or dairy-based smoothies that may leave strong odors or residues. If you do use it for such drinks, be sure to clean it thoroughly afterward to prevent lingering smells. Additionally, avoid filling the cup to the brim, as this can cause spills when you insert the lid. Leave some space to allow for liquid expansion and easy sipping.
The cup is also not suitable for use in a car cup holder if it doesn't fit snugly, as it may tip over. Instead, carry it in your bag or use a suitable holder. By using your Brew Cork QuickSip as intended, you'll get the best performance and avoid damage.
- Fill the cup only up to the fill line to prevent spills.
- Avoid using it for carbonated drinks to prevent pressure buildup.
- Carry the cup upright in a bag or use a cup holder that fits.
Don't: Forget to Store It Properly
When you're not using your Brew Cork QuickSip, store it with the lid off to allow air circulation and prevent moisture buildup. This is especially important if you've just washed the cup, as trapped moisture can lead to mold or mildew on the cork. Store the cup in a dry, cool place away from direct sunlight, which can fade the cork and degrade the glass over time.
If you're stacking cups, place a cloth or paper towel between them to prevent scratches. Avoid stacking heavy items on top of your cup, which could crack the glass. By storing your cup properly, you'll keep it in pristine condition and ready for your next drink.
- Keep the lid off when storing to allow airflow.
- Store in a cabinet away from direct sunlight.
- Use a protective sleeve or cloth when storing with other cups.
By following these do's and don'ts, you'll extend the life of your Brew Cork QuickSip and enjoy every sip to the fullest. Remember, a little care goes a long way in maintaining the beauty and functionality of your cup.
