I am an electronics tech servicing 10+ year old amateur radio gear.  The
trouble I am having is with a single sided through-hole board.  Areas of
the board are covered with wax.  Over time the boards malfunction as the
wax works its way into the solder.  Hand resoldering is a nightmare as the
wax continues to wick towards the connection.  Heating the board and
draining the wax away does not help as some wax residue is left.  Also,
components become damaged from the air gun.  The boards are also covered
in contact cement that has become corrosive and conductive.  Currently we
are using Methaline Chloride to soften the glue and then pick it away.
Questions are as follows: 1) How can the wax be completely removed? 2) How
can the glue be removed without using such a toxic substance as paint
stripper? 3) Is there an economical device that can be purchased to reflow
these old boards without hand resoldering hundreds of cold/contaminated
connections?  Any help would be greatly appreciated!
