I have retainers and don't know what i should do to clean them?

I just got retainers and they have a plastic taste and i wanted o know how i could get rid of the plastic taste. Also how do i clean them?

Retainers live in your mouth along with bacteria, plaque, and leftover food particles. You'll want to clean your retainer every day by taking it out and brushing it with your toothbrush and toothpaste. You can also soak it in mouthwash or a denture-cleaning agent to freshen it up and kill germs.
Because the plastic of your retainer can crack if it gets too dry, you should always soak it when it isn't in your mouth.
