it just depends on your browser whether its chrome explorer firefox etc. should be listed in the options on some
Firefox - go to the 3 bar button on the top right and click on it. then go to options and click on privacy you will see recent history/individual cookies. You can choose to delete individual cookies or erase them within a timeframe of a day week or everything
chrome - go to the 3 dot button on the top right and click on it. then go to more tools and click on it. you should see the option clear browsing data.
explorer - go to the 3 dot button on the top right and click on it, then go to settings and click on it. go to clear browsing data. its basically the same as chrome after that.
On Internet Explorer, it's under "Tools" at the top. On Google Chrome, click the 3 dots on the upper right hand side of the page and it's under "More Tools".
And if you're still using IE, you should probably consider Chrome or Firefox, both of which are far better.
