CloudFront: How to clear cache

Question

I am trying to remove the cache from my CloudFront, but I am going crazy with this.

What I did so far:

1. Create bucket and set policy.
2. Copy the endpoint from that (I test it on browser, and it's working).
3. Create the CloudFront with the Min TTL: 1 sec.
4. Downloaded S3 Browser and set HTTP Header to max-age=1

But still, if I update my S3 bucket, my Cloudfront is showing files that I already changed.

Can you guys point me on how to do it the right way? If there is a way to just clean cache when I want, even better, I just want to upload my files, see if CloudFront is showing the correct thing on Web, then I don't care anymore about the cache.

Thank you!

You can use invalidation which is described in the documentation.

Recently this functionality was updated to allow to invalidate many objects at once. You can specify a path prefix and use : * to clear all cached objects.

However before deciding to use invalidations, please consider using versioned objects. There are many benefits to them described in the article referenced above.
