remoteWebDriver = new FirefoxDriver(capabilities);

remoteWebDriver.quit();

Run this from Command line:

taskkill /F /IM geckodriver.exe

Or better of, put it in a batch file and run the file every time you want to clean up.

You can also do it from your code if you want, before you start running:

boolean isDebug = java.lang.management.ManagementFactory.getRuntimeMXBean().getInputArguments().toString().indexOf("-agentlib:jdwp") > 0;
try {
    if (isDebug)
        Runtime.getRuntime().exec("taskkill /F /IM geckodriver.exe");
} catch (IOException e) {
    e.printStackTrace();
}

Only in debug to avoid killing instances on slave if you're running in parallel.
