I have a skype conversation saved in word (the other party knows it is being saved).

There are lots of timestamps in it like this [06/08/2014 23:23:31] and this [01:50:19]

How can I use replace to replace all of these with a blank space, the conversation is currently over 560 pages so I do not want to do it manually, also it is an ongoing story so will need to do it over and over again.

I have tried using * and ? for wildcards but it just removes the punctuation in the middle and not the numbers.
