Hi, I have used deoxit that way as well. It works fine...just don't get it on any painted surfaces as it can damage them. In older RCA jacks you can spray it on a Q tip and swab the holes. It usually works. As a general rule don't use WD40 on anything audio. It tends to leave a residue that will build up over time and cause a problem worse than the one you wanted to cure.
