Wood items are pretty vulnerable to salt stains. This is because salt deposits on wood start seeping through the wooden item over time. Furthermore, they eat away at any applied varnish making the item dull. Therefore, any salt stains on wooden tiles, cupboards, or tables should be immediately wiped off to prevent them from ruining the item. To remove any stubborn salt stain, spray the spot with a vinegar-water solution and wipe it out with a clean microfiber.
