It will probably clear out SOME of the carbon build up in there provided you do the treatment through the brake vacuum line. However, the only real way to get ALL out would be during a port & polish, and removing the upper intake manifold (always risky and may involve cracking and/or milling later). The vacuum line treatment should be good enough.
