When there’s winter, there’s salt stains. On your boots, on your door mats, on your lovely floors. Get rid of it naturally with white vinegar diluted about 1:2 with tap water. Salt is alkaline while vinegar is an acid. Put them together and you get some oxygen making fizzle on your shizzle. All of a sudden salt stains are gone and surfaces are naturally cleaned.
If only it were harder than that.
