I've caught a few of the Anthea progs and have learnt that:
Putting a stick of chalk in a box with silver jewellery will stop it tarnishing.
Use a white slice of bread to catch broken bits of glass
Use gin to clean your diamonds
Use vinegar and or Bicarb to clean absolutely everything
To clean silk/dried flour. Put it in a big paper bag with a bit of salt in and give it a good shake.
Do you have any great ones to share.
