Stains on windows

Iv been asked to remove the stains from the windows in the pic attached.

I’m thinking it’s the splash back from the concrete window ledge as it’s only at the bottom. And they have concrete lintels above the window and the ledges. 

Once cleaned how should the customer stop this from happening again.

Your help and advice on chemicals would be much appreciated.

Thanks

Looks like lime scale ????? Viral or similar should hopefully remove it .

Difficult to stop it happening again unless you seal the concrete sills with a sealer Mabe????
