I can answer for dobebug, because there is really only one answer:
If when you take the ears down, and all is good. (No irritation or infection, etc.)... Take only enough time to gently clean and inspect the ears. As soon as they are dry, put them back up in posts right away. Aim for 1/2 hour for the ears to be down. But, in reality, just get them back up in a reasonably short amount of time.
If you think that here might be an issue with the ears, generally that will need to be addressed before you can re-post.
But that would not be the norm.
Also... You should never be sorry for asking questions. In fact, you should always come back and ask if you have anything that you are concerned or unsure about. There is a good chance somebody can steer you in the right direction.
