Maggots in the hoof are not quite as bad as fly strike maggots in that they can actually help clean up the hoof by eating dead material and not live. Used in human medecine too to clean out dirty wounds which are not easy to treat otherwise (not sure I would like being on the receiving end with all that wriggling
). What you did was fine.
Making bread or pastry gets rid of the smell
Rubbing with half a lemon might help too. I couldn't get rid of yesterday's smell of sheep poo in spite of dozens of hand washes until I washed my hair this morning....... I think most of it is psychological in that after such a horrible smell, anything you sniff afterwards will smell of maggots.
Don't forget that if you are sending your fleeces to be processed by the Natural Fibre Co and similar, or selling to handcrafters, you shouldn't have applied Crovect or any other anti Fly Strike stuff for 3 months beforehand.
