Clean copy
What you send when the point is the text, not the argument about the text — and why it usually travels alongside a redline rather than instead of one.
What it is
A clean copy is a version with all changes accepted and all markup removed. No underlining, no strike-through, no comments, no coloured text — the document as it would read if the negotiation had never happened.
It is also called a clean version or, once it is final, an execution version. The word "clean" is doing the same work as in "a clean sheet": nothing on it but the thing itself.
Why both are sent
Convention in most transactional practice is to circulate a clean copy and a redline together, and the two are read for different purposes.
The redline answers "what did they change?", which is what you read first and what determines whether there is anything to argue about. The clean copy answers "what does the clause now say?", which is what you read when you have stopped arguing and started checking that the sentence works. Reading a heavily marked-up clause for meaning is hard; the strike-throughs are exactly the words your eye keeps trying to include.
Sending only a clean copy invites the reply "can you send a comparison?", which costs a turn. Sending only a redline invites a misreading of a clause that has been marked up twice.
Making one
In Word, a clean copy means accepting all changes and then confirming that tracking is off, and separately removing comments and any hidden metadata. Accepting the changes and leaving tracking on produces a document that looks clean on your screen and starts recording again the moment the other side types.
In Redline Pad, the Revised copy button gives you the clean text of the revised version — every change accepted, nothing marked. It is the same text you pasted into the revised pane, which is the point: the tool does not rewrite what you gave it.
