Learn the simple steps to keep your Mepal Campus Flip Cap Bottle fresh and leak-free. Includes tips for the Little Dutch Fairy Garden design.
Quick answer
Disassemble the flip cap, wash all parts in warm soapy water, rinse thoroughly, and air-dry completely before reassembling. Avoid harsh chemicals or the dishwasher for the cap.
Why regular cleaning matters
Even if you only fill your Campus bottle with water, bacteria and mold can grow in the flip cap mechanism and around the silicone seal. A quick daily rinse isn't enough to keep the drinking spout and button area truly clean.
The 600 ml Little Dutch Fairy Garden bottle is lightweight and leak-proof, but the flip cap design has small crevices that trap moisture. Regular deep cleaning prevents odors and ensures the one-button opening mechanism stays smooth.
What not to use
Do not put the flip cap in the dishwasher. High heat can warp the plastic and damage the spring mechanism. Stick to hand washing with mild dish soap and a soft brush.
Avoid bleach, abrasive scrubbers, and vinegar soaks. These can degrade the silicone seal over time, causing leaks. A simple baking soda paste is safe for stubborn stains.
Step-by-step cleaning guide
- Disassemble the flip cap: Press the button to flip open the spout. Pull the silicone seal out from under the cap. Remove the small rubber gasket from inside the lid if present. Keep all parts together. Don't force the seal; it should slide out easily. If it feels stuck, soak the cap in warm water for a minute first.
- Wash all parts in warm soapy water: Fill a bowl with warm water and a few drops of mild dish soap. Use a soft bottle brush for the main bottle and a small brush (like a straw cleaner) for the flip cap spout and button crevices. Scrub the silicone seal gently with your fingers. A common mistake is skipping the button area. Food and slime build up behind the button, so lift it slightly while scrubbing.
- Rinse and air-dry completely: Rinse every part under running water until no soap remains. Shake off excess water and place all components on a clean drying rack. Do not reassemble until every piece is bone-dry. Moisture trapped inside the flip cap is the #1 cause of mold. Let it dry for at least 4 hours or overnight.
- Reassemble and test: Reinsert the silicone seal, pressing it evenly into the groove. Snap the flip cap back onto the bottle. Fill with water, close the spout, and turn upside down to check for leaks. If the bottle leaks, the seal is likely not seated properly. Remove and reseat it, ensuring no twists.
