Cleaning contacts, What first?


I've been using the Caig ProGold contact enhancer for years and find it to be a very worthwhile product... my question is this: I've just purchased the Mapleshade Silclear contact enhancer and I want to do a complete system contact cleaning/enhancing from power cords to I/C's, etc.... Should I start from scratch with some sort of "Pure cleaner" like an alcohol or something (Isopropyl or ?) then to the Caig and then to the Silclear or is all that just way too overkill/unnecessary? Honestly I haven't been using anything but the Caig for several years now (every few months or so)... am I overdue for this complete cleaning project [as described] or what? Advice on 'what' and in 'what order', would be appreciated. Thanks in advance.

Before using the Silclear, read this previous thread http://forum.audiogon.com/cgi-bin/fr.pl?raccs&1077564712&read&keyw&zzsilclear
and you may decide not to apply it. While initially spectacular, it did make my system muddy over a few months time. Other people report the same issue.
I would go for ART TR-30. It is the best one I have used. Unfortunately it is only available from the ART Italy, no dealer at the present for US/Canada.
After reading the post gammajo mentioned above, I have concluded the people with bad results used way to much or not the thin layer thats only needed. I have it on my system and I will have to take it off some connections to see the results due to having it on around 2 years.
This has been a very busy and enlightening thread and I thank you all for your input so far. Rushton, I have isopropyl alcohol but it's "Rubbing" and only 72% pure so I'll have to get a more 'purer' version... Gammajo: thanks for the very informative link, it's starting to give me second thoughts about using the Silclear at all and that maybe my best bet is getting some Caig Deoxit to apply first,(or simply using some pure Isopropyl alcohol or Kontact as a cleaner) and then simply following up with the regular Caig Progold which I've always used. The other option might be the Walker SST which seems to have a better following or the last choice might be simply to use the Silclear but only on the few easy to clean off locations such as my speaker spades and amp binding posts... things I can easily get to. Maybe the male ends of my power cords, but that will make me worry if I could be degrading inside the wall socket over time (which would certainly be a disaster). The consistent consensus that keeps coming up though is: don't use too much/ keep it down to a very thin coat, and it really is difficult to remove once its been applied. I'll let you all know what I do (at this point I may chicken out on it even though I've already bought it) or I may play with it a little, as above. Once again though: thanks to all. Happy lissn'n.
