need help removing some stains on paint

[Nismo 1234]

hey,
a buddies new benz e350 had some things drop down on it. its now stuck on it cuz he didnt wipe it off right away.
anyway, the stain came because the pipe on top of his garage broke and water started to drip on the car. The it went through wood before dripping on the card. Now the stain is not really coming off.....
any suggestion on what we can try without damaging the paint??

thanks

calcium deposit not pretty
there are a couple of ways but they not pretty too

muriatic acid will take it right off but if you screw up. gg, then you polish it
or
you can wet sand it out then polish it

hey thanks for the quick reply, still searching for simplier ways to remove it since its a brand new car and i dont want to screw it up for them and end up paying to paint the rear bumper again.
