This code should be removed

You probably have seen comments like this. "This code should be removed. (following out commented code)." "This should be re-factored." "This is a hack, we should find a better solution."Trashbin

"Should" is the trigger here. When talking code, there is no should. You'll have to replace should with must.You must re-factor this piece of code. You must delete this code and not just comment it out (you're working under source control, aren't you?)

To keep your code maintainable you have to maintain it. This sound obvious, but there aren't many developers who practice this. Constant re-factoring, keeping the code clean and readable and simplify complexity. You can do this while working on a piece of code. By doing guerrilla re-factoring you are able to keep your software maintainable.

If you are writing new code, keep maintenance in mind. Don't write hacks, you're not rewriting it any time soon. Yes it saves you a few minutes now, but it'll cost you a lot more later on. It's easier to invest a little bit time now: it'll pay back. Re-factoring will cost exponentially more after time.

So: produce clean code now and re-factor wherever you can. This will keep your code maintainable and therefore cheaper. It is a small investment, but it'll give you great benefit.
