You can clear the cache whenever you want via Cache Timeout page.
How does it work?
The cache timeout feature uses wp_schedule_event() and it works when someone visits your WordPress site. If you don’t have any visitors, the function won’t work.
Adding a Cache Timeout Rule
If you want to add a new rule, you should push on the “Add New Rule” button.
The system is case insensitive.

If you want to delete the cache of the home page, you need to select “Home Page”.
If you want to delete the cache of “contact-us” , you need to select “Is Equal To”.
If you want to clear the all cache, you need to choose “All”.
