Frequently Asked Questions
What actually prevents dressing from leaking in a salad container?
Three things matter: a silicone or rubber gasket that creates a continuous waterproof seal, a locking or clamping system that holds the lid tight against the gasket, and a physical compartment or sealed dressing cup so liquids aren’t sitting against a seam. All three together give the best protection.
Are glass containers better than plastic for preventing leaks?
Glass resists odors and staining and pairs well with strong silicone gaskets, so it often gives a more reliable long-term seal. Plastic can be leakproof too, but thin lids and poorly attached gaskets are common failure points—inspect the seal quality rather than relying solely on material.
How should I care for gaskets and small dressing cups to keep seals reliable?
Remove gaskets and small cups and wash them after each use, dry thoroughly, and inspect for cracks or deformation. Replace silicone gaskets if they become stretched or misshapen. Avoid harsh scrubbing that can nick sealing surfaces; most gasketed containers are dishwasher-safe but top-rack cleaning and periodic hand checks extend gasket life.
