How often do you clean cables? And which types do you clean most often?

So, how often do you clean your cables? Such as with Deoxit or other cleaning solution?
- weekly?
- monthly?
- annually?
- other?
- never?

And do some types of cables benefit more than others from cleaning? I'm thinking analog cables such as interconnects and speaker cables might need cleaning more often than digital cables such as coax and USB. What's your experience here?

Also, when you clean cables, do you also clean the connectors on the units? Such as RCA or speaker outputs and inputs?

Lastly, for now, I mentioned Deoxit among cleaning solutions. If you do clean cables, what are your favorite products and why?
