Quick answer
Wash your Zojirushi SW-EAE50 food jar by hand with warm soapy water and a soft sponge after each use. For deep cleaning, use a baking soda solution to remove stains and odors without damaging the vacuum insulation.
Why hand washing matters for your food jar
The SW-EAE50's vacuum insulation and tight-sealing lid rely on a precise construction. Dishwasher cycles can expose the stainless steel to harsh detergents and high heat that may degrade the gasket over time, leading to leaks or reduced heat retention. Hand washing preserves the jar's performance and extends its life.
The 18/8 stainless steel interior is durable and sanitary, but it can absorb strong odors from foods like spicy soups or curries if not cleaned promptly. A quick rinse after emptying prevents residue from drying and clinging to the surface.
Step-by-step cleaning guide
- Rinse immediately after use: Empty the jar and rinse it with warm water. This prevents food residue from drying and sticking to the stainless steel interior. Don't let the jar sit empty for hours before rinsing—dried food is harder to remove and can trap odors.
- Hand wash with mild soap and a soft sponge: Fill the jar halfway with warm water and add a drop of mild dish soap. Use a soft sponge or bottle brush to scrub the interior, lid, and gasket. Avoid abrasive scrubbers or steel wool that can scratch the surface. Never use bleach or chlorine-based cleaners; they can damage the stainless steel and gasket.
- Rinse thoroughly and air dry: Rinse the jar, lid, and gasket with clean water until all soap residue is gone. Leave the jar open and upside down on a drying rack until completely dry before storing. Storing the jar with the lid on while still damp can trap moisture and cause mold or odors.
- Deep clean to remove stains or odors: For stubborn stains or lingering smells, fill the jar with a mixture of 2 tablespoons of baking soda and warm water. Let it soak for 15-30 minutes, then scrub gently with a soft sponge and rinse well. Do not use vinegar or acidic solutions for deep cleaning; they can dull the stainless steel finish over time.
- Clean the lid gasket separately: Remove the silicone gasket from the lid (if possible) and wash it by hand with soapy water. Rinse and dry it completely before reinserting. A dirty or worn gasket is the most common cause of leaks—inspect it regularly and replace it if cracked or stretched.
