Girls, Ladies is there a good tool you use to get the little dirty spots clean on carrots?

I've decided to try to cook carrots without peeling them, but unlike potatoes no matter how much i rinse them under the water they have these little spots on them with little flecks of dirt that won't come out. I noticed I can get it out if I use my nails but that would take forever to do just one carrot. Is there a process that is much faster but doesn't tear up the carrot skin?
