The deterioration of sound quality over time occurs anytime you clean signal path connections with or without contact enhancers. Contact enhancers are a mixed bag and with them a deterioration anyway. The silver paste products were designed to be used on cable connections that will not be changed out or disturbed. They achieve peak performance after a few days. They do dry out and flake off so the cleaning job becomes more involved and not as complete since the flakes get into hard to reach places.
So if you find yourself becoming bored with your system and you have the itch to upgrade a component because of it, clean the contacts. Doing that on a regular basis keeps the system at the top of its' form. Contact enhancers are a questionable value and become less so if you have an established regimen for keeping the connections clean anyway.
