[concours] New Member

Hi Listers, I am a new member having just purchased a 1990 XJ40 Sovereign
4.0L Sports.My long term goal is to have her prepared, by myself, to
concourse condition(without the expense of garages). My first question, to
steam clean or not to steam clean. I have heard so many bad reports of the
electrics that I am wondering if there are any good proprietary brands that
are better.
