residential steam return line

any tricks off the trade for a partly clogged 1" return line. Half of the line is behind paneling but only one radiator does not heat . Was going to install a vent at the end of the main but took the nipple out and had water.

    You are going to have to try to flush it out, which may be much easier said than done. Depends on where, and at what kinds of fittings, you can get at it.
