How to clear cache?

Hi, I know it may sound like a dumb question…but is there a way to manually clear the cache specifically for the calendar?

I vaguely recall there being a way and I THOUGHT I’d done so recently. Just can’t find it now.

Found an old post somewhere advising to go into …plugins/all-in-one-event-calendar/cache and clear the cache there.
Something which I did have a look at today; and I found 111 css files. No clue what to do next. That is, if in fact that advice still holds.
