What's the most effective product or process to eliminate lawn Clover?

Thank you for the opportunity to get some professional advice. I have Clover patches taking "root" in my lawn. Some as small as just a few sprigs, others 7-8 feet in diameter. What is the most effective method or product to use to kill this off without damaging the lawn, and then the most effective means to prevent it's return?
