Hello Manuel,
Quote:
- More expensive than technical grade. - The organic residues in edible vinegar (made from wine, fruit juice, added herbs) may give yellowish/brownish hues when using vinegar as an etchant. BTW, I bet that the main active ingredient when utilizing ketchup is vinegar. With some starch, you could easily cook a cheap acetic acid "pudding" for a less messy application on blades...
