What type of lube is best to use for the blades on a cross-cut shredder?

I have all sorts of lube in my home workshop and I don't want to go and
buy some special shredder oil if it's hardly any different to what I've
got.
Just use any old oil or grease. I use some spray-on lithium grease -
works like a charm.

For safety reasons it's to apply the lubricant to a sheet of paper (if
it's a very light spray like WD40 allow it to evaporate a bit) and then
shred it.

Don't do what I did the first time - and just spray the stuff into the
slot - or at least, if you do, unplug it first. By the time, the little
straw triggered the sensor on mine, a nice explosive mixture had
developed around the motor. Left me with quite a lot less hair and eyebrows.
