Catherine this subject has been much discussed, lots of theories, lots of recommendations and no proof of anything very much as far as I can see. If you've got this stuff you have my sympathy. I'm sure someone with experience of it will come on and give what advice they can.
I think it can be done with persistence.
I'm relieved to say it's never been my responsibility to deal with it
