About a month ago I saw a witchy tips post with all the uses of salt, mostly for protection against evil, warding, and luck.
The list was pretty basic like how salt can be used to drive away evil spirits. (This is where the superstition of sprinkling salt over your shoulder comes from) or how a circle of salt can protect against black magick and evil forces.
The tips were mostly correct until there was one for "attracting wealth" by placing your bank card (Debit card) in salt.
Please do NOT do this! This is as foolish and as harmful as smudging (with sage) when used on antique books. (smoke damages book paper and binding.) There are other non-invasive ways to cleanse used books such as with crystals.
Now with cards and salt, the salt can get into the card and damage both the magnetic strip and the microchip inside the card. You can damage your card and accidentally render it unreadable.
