A friend of mine is using an old microwave to sterilise soil before
using for cuttings/seeds etc. in his greenhouse.
Is it worth doing?
Will it kill off "good things" as well as bad?
Any comments?

It will work just fine and yes it will kill off everything which is what you
want. Put the soil in a plastic bowl and cover with plastic wrap. Cycle
till the plastic wrap forms a huge bubble. Let it rest till the plastic
resembles a vacuum pack. Remove the plastic, stir and repeat the process.
