Clearing cookies, cache, and history in Chrome for Android

Step #1. First up, you need to navigate to Chrome's Privacy tab by going to Triple Dot menu button > Settings > Privacy.

Step #2. Once inside the Privacy tab, just tap on the large blue button at the bottom ('CLEAR BROWSING DATA'). After that, select one or more categories to wipe. Finish the process by tapping on the 'Clear' button.

Step #3. What if you want to only wipe data for a specific site, though? To do so, go back to the root menu, and then Site Settings > All sites. From there, hunt down the offending site you want to lose its all.

Step #4. Once inside, just tap on the large blue 'CLEAR & RESET' button and okay the prompt. All data related to that website, including any previously-granted permissions, will be wiped out and you'll be able to start clean.
