doesn't manhattan's water system come from westchester, or?? not manhattan. however, maybe it picks up minerals in the pipes in your apartment bldg??
if it is, then maybe you need to low poo more often. i'd also use something like cj daily fix to cowash as it has an ingredient that helps to remove minerals.
not sure. i am sure, tho, that others more knowledgeable will be able to help you more.
