Quick Answer
To keep your Bentgo stainless steel snack box looking new, hand wash it with warm soapy water and a soft cloth, dry it immediately, and avoid abrasive cleaners. For stubborn stains, use a paste of baking soda and water, then rinse and dry thoroughly.

Stainless steel lunch containers are prized for their durability and sleek look, but they can show fingerprints, water spots, and stains over time. Proper care keeps your Bentgo stainless steel snack box looking as good as the day you bought it.
Unlike plastic containers, stainless steel requires a bit of attention to avoid scratches and maintain its shine. With the right techniques, you can easily remove common stains and keep your container in top condition for years.
Why Stainless Steel Needs Special Care
Stainless steel is resistant to rust and corrosion, but it is not immune to smudges, discoloration, and scratches. The protective layer that gives stainless steel its shine can be damaged by harsh cleaners or abrasive scrubbers, leading to a dull or scratched surface.
To preserve the appearance of your Bentgo stainless steel snack box, always use gentle cleaning methods. Avoid chlorine-based cleaners, steel wool, and abrasive pads, as these can scratch the surface and remove the protective layer.
- Always hand wash your stainless steel container; dishwashers can cause water spots and potential damage.
- Dry immediately with a soft cloth to prevent water spots and maintain the shine.
Everyday Cleaning Routine
For daily cleaning, rinse the container with warm water to remove food particles. Add a drop of mild dish soap to a soft sponge or cloth, and gently wipe the interior and exterior. Rinse thoroughly with warm water to remove all soap residue.
After washing, dry the container completely with a soft, lint-free cloth. This step is crucial to avoid water spots and maintain the bright finish. Regular hand washing prevents buildup of oils and residues that can dull the surface.
- Use a non-abrasive sponge or cloth to avoid scratching the surface.
- If you notice fingerprints, wipe with a microfiber cloth dipped in a little white vinegar for a streak-free shine.
Removing Stains and Discoloration
Stains from tomato sauce, mustard, or other pigmented foods can sometimes leave a mark on stainless steel. For these, create a paste with baking soda and a small amount of water. Apply it to the stained area and gently rub in the direction of the grain with a soft cloth. Rinse and dry thoroughly.
For tougher discoloration, you can use a small amount of white vinegar on a soft cloth to wipe the surface. Vinegar helps break down residues without damaging the steel. Always rinse well afterward to avoid any lingering smell.
- Test any cleaning method on a small, inconspicuous area first to ensure it doesn't affect the finish.
- Never leave acidic foods in the container for extended periods; clean promptly to prevent etching.
Drying and Polishing for a Like-New Look
Drying is just as important as washing. Always dry your stainless steel container immediately after washing with a soft cloth. This prevents water spots and mineral deposits that can dull the surface.
For an extra shine, you can polish the exterior with a small amount of olive oil or a commercial stainless steel polish on a soft cloth. Apply in the direction of the grain and buff gently. This step is optional but can help maintain a like-new appearance.
- Avoid using paper towels, as they can leave lint and may be abrasive.
- If you notice scratches, they are often only in the surface and can be minimized with a stainless steel scratch remover, but test carefully.
Step-by-Step Cleaning Process
- Rinse and Disassemble: Rinse the container with warm water to remove loose food. If there are any removable parts like lids or gaskets, take them off and wash separately. Checkpoint: Ensure no food particles are stuck in corners or crevices.
- Wash with Mild Soap: Use a soft sponge or cloth with mild dish soap and warm water. Gently scrub the entire surface, inside and out, in the direction of the grain. Mistake to avoid: Do not use abrasive scrubbers or harsh chemicals that can scratch the steel.
- Rinse Thoroughly: Rinse all soap residue with warm water. Leftover soap can leave a film that attracts dirt. Checkpoint: Run your finger over the surface to feel for any slippery soap residue.
- Dry Immediately: Dry the container completely with a soft, lint-free cloth. This prevents water spots and maintains the shine. Mistake to avoid: Do not air dry, as this can cause water spots.
- Remove Stains with Baking Soda Paste: For stubborn stains, mix baking soda with a little water to form a paste. Apply to the stain, gently rub with a soft cloth, then rinse and dry. Checkpoint: If the stain persists, repeat the process or try a vinegar wipe.
- Polish for Shine: Optional: Apply a small amount of olive oil or stainless steel polish to a soft cloth and buff the exterior in the direction of the grain. Checkpoint: Ensure the polish is fully buffed off to avoid a sticky residue.
