How do I clean a black granite composite sink?

Tried many cleaners but can't find one that takes off these white streaks-don't know where these are coming from! Thanks

Any idea who made the sink? Call them and ask.
Thanks. Their papers did say to use mineral oil on a regular basis but that seems like covering up the problem.
Mineral oil is the way to go. I scrub mine with Bar Keepers Friend, rinse well and then coat it with mineral oil and then wipe the oil off with paper towels.
