Dishwasher works for me, but only whilst Lady Nasher is out.

Do you have any sharp sand, what you use for brick Mortor?

I've put small parts in a bag of it before and rolled it around in my hands for a while.
It works just like a mechanical 'Rumbler' if you've ever seen one.
But you do need to clean it all out properly of course.

I've often wondered if you could use something else. I have some Aluminium Oxide blasting media in the garage which I picked up for this very task and never tried it.
