If some is good, is more better?

Good afternoon!  I’m definitely in the “too much is barely enough” camp.  I need to clean all the contacts in my system and have been researching both the Kontak - ECO3x contact cleaner as well as the DeoxIT Gold Gx3 cleaner.  Would there be any benefit to using both products?  If so, in what order would you use them to gain the maximum benefit?  Any advice is most appreciated!  Thanks!
