Here's a further hint on micro-fibre cloth usage.
Often, they have quite enough bite to be used dry, and water is something we don't want to get near our electricals, let alone our electronics, anyway.
What about when you need that bit extra; a damp cloth? Getting a microfibre cloth wet,
quite apart from the safety aspects, actually seems to reduce its effectiveness. Wetting it, and wringing out the water still
leaves too much. This is what I do: run a little water into the sink, let it run away, so that the bottom of the sink is wet, but no standing water. Put the cloth flat on the remaining film of water --- and you have a nicely dampened
