Remedy kills legumes. 2-4D kills broadleaves. One thing to remember though, none of them sterilize the seeds & clover puts off a kazillion seeds that stay viable in the seed bank for years. So if was once there, it will be back with the right growing conditions.Clover is a legume, which adds nitrogen to the soil. If you add nitrogen (high first number fertilizer) the grass will take over. Im not sure how to help outside of the lawn though.
