Operating Instructions
Filling the Canisters
- Ensure the canister is clean and dry before filling.
- Place the desired dry food item (e.g., bread, cereal, cookies, pasta, pastry, rice, spices) into the canister.
- Do not overfill. Leave adequate space for the lid to close securely.
Sealing the Lids
Place the stainless steel lid firmly onto the canister opening. The lids are designed with a flip-top mechanism for easy access and a secure seal. Ensure the lid is properly aligned and pressed down to create an airtight environment, helping to keep contents fresh.
Opening the Canisters
To open, simply lift the flip-top lid. If the seal is tight, gently twist the lid while lifting.
Maintenance
Cleaning
The Mainstays Classical Canister Set is not dishwasher safe. To clean, hand wash each canister and lid with warm, soapy water. Use a soft sponge or cloth to avoid scratching the surfaces. Rinse thoroughly with clean water and dry immediately with a soft, lint-free towel. Do not use abrasive cleaners or scouring pads, as these can damage the finish.
Storage
Store the canisters in a cool, dry place away from direct sunlight and extreme temperatures. Ensure canisters are completely dry before storing to prevent moisture buildup, which can affect food quality.
Troubleshooting
Lid Not Sealing Properly
- Check for Obstructions: Ensure no food particles or debris are caught between the lid and the canister rim.
- Proper Alignment: Verify that the lid is correctly aligned with the canister opening before pressing down.
- Overfilling: Do not overfill the canister, as this can prevent the lid from sealing securely.
Water Spots After Washing
- Always dry the canisters and lids immediately after washing with a soft, lint-free cloth.
- Consider using filtered water for rinsing if hard water is an issue.
