Acrylic paint is water based so as long as it's not dry you can wash it off with water, just swish it around in a plastic cup of water or soak them and then swish them. If the paint is dry you might have to let it soak for a long time or use mild acetone (nail polish remover).
Water. Actylic brushes can easily be cleaned with water. The only time you may have problems cleaning acylic paints off brushes is if you leave them out too long and the paint dries in the bristles; that's why when painting with acrylics, always keep a containter of water nearby to keep your brushes soaking in until you need them again (while painting). When you're done painting, wash your brushes in the sink and properly dry them. Having dried acylic paint in the bristles of a brush pretty much means your brush has died and that you need to get a new one.
