stains on concrete

How do I clean the white stains on my new colored concrete patio.
Our water has high lime content
What can I use to clean the patio?
Thanks

as long as the concrete and the sealer have cured...i would go with a clr type product...wet the area allow to sit wet 10-15 mins..scrub with a mild aggressive deck brush and rinse off

you can find such products at most home improvement stores in painting isles or cleaning
