Well, since Dave (The Medway Handyman) said that steam cleaning windows was
indeed OK, she's done them - and he's right; absolutely brilliantly
sparkling clean )

We tend to be a bit lazy in defrosting the freezer and haven't done it in
over a year so it's desperately in need of sorting. I saw a gleam in her eye
as the idea to use the steam cleaner bubbled up to the surface but again, I
had serious misgivings about it so I googled and found dozens and dozens of
people who use them for that purpose, so off she went.

Just 20 minutes ago, each shelf of the freezer had at least 1" of ice on
it - and now, it's darn-near all gone! )

Amazing.
