As to cleaning with vinegar I am not nearly as scientific as either Jean or Marco. I buy ordinary white household vinegar, I have not the slightest idea of its acidity, I never dilute it. I simply wash the blade with detergent to get rid of any grease, and soak it in the vinegar. I inspect it once or twice a day and brush it as well as pick off the rust with a sharp tool, then I put it back into the vinegar. It might take me a week or more before I'm satisfied that it is clean.

Jean has my utmost admiration if he can get a truly dirty blade clean in 24 hours with only 2 brushings. Incredible! You're a better man I am Jean.


my way to clean blades (with rust difficult to remove with other easier systems) is only empirical and rather fast.... sorry for my bad english
