Black Salt, I know what it does, but I'm not sure how to use it. Options

Hello, I've recently bought some black salt from a metaphysical shop. I know what it's used for, but not sure how to use it.

Breaks hexes, un-crosses, repells evil forces, and keeps away bad neighbors ^^ but I'm not sure if I'm to throw it all around my house, or what.... so any input would help, I'm new at powders and others salts that aren't table and sea salt.

~Paradox~

I would say, use it in combination with a sigil or symbol.

Example:
Special banishing symbol on paper in center of sheet, with salt poured in a circle around it?
