Your pic is actually very related. You can use a slice of lemon to rub away all the stains (those are made of calcium, lemon simply dissolves them away) just be careful to avoid using it on marble or concrete or whatever may be weak to acids. By the way any acid will do (vinegar... Maybe mustard)

Former house cleaner here. We used a "magic eraser" sponge with just water and a dollop of shampoo. Scrub the effected area, rinse, and repeat as necessary until the hard water stains are gone.

Are they crusty? Picture related.
Are they not crusty? Weak acid (>>1132978) or light abrasive (>>1132980).
