How does Victorinox say to remove stains or corrosion?
For Victorinox table and kitchen knives: wash under running water after use, and remove stains or corrosion with an abrasive sponge, as its care sheet directs. These are the sheet’s cleaning and removal instructions; it specifies no chemical mixture or treatment time. Published November 5, 2015 and checked November 4, 2026, the sheet applies to its named knife range.
Can I use that method on a Shun or wooden-handle folder?
Shun warns against scouring pads, steel and gritty cleansers, so do not transfer Victorinox’s abrasive instruction to Shun. Opinel’s wooden-handle guidance calls for drying before closing and avoiding prolonged soaking. Use each maker’s own instructions for its finishes and handles.
What if corrosion remains or affects a mechanism?
Ask the maker for model-specific service guidance when its care sheet does not cover the condition. This source does not supply an acid treatment, a soak duration or a repair procedure for pitting or a damaged mechanism.
