Brass Cleaner - cooking recipe

Ingredients

6 tablespoons salt
6 tablespoons flour
6 tablespoons white vinegar, approximate

Preparation

Measure salt and flour into a glass bowl.
Add vinegar slowly to moisten and stir into a stiff paste. (Slightly more or less vinegar may be required depending on local humidity conditions.).
You can always add more vinegar if the paste is too dry, but it is difficult to firm up a runny paste.
