Setup, Compatibility & Care
Before the first use, it is recommended to wash the containers in warm, soapy water. To maintain the airtight seal, avoid using abrasive sponges that could scratch the plastic or compromise the locking tabs. While the containers are top-rack dishwasher safe, high heat can occasionally warp plastic over time; hand washing is the best way to prolong the lifespan of the clips.
- Microwave: Remove lid entirely or place it loosely on top. Do not seal while microwaving.
- Freezer: Suitable for long-term storage, but allow space for contents to expand if they contain moisture.
- Stacking: Designed for vertical stability, but avoid placing heavy non-Sistema items on top of the lids to prevent damage to the locking mechanism.
