I eat heaps of mushrooms and just wash them, I never have a problem with them going soggy I just run them under water while I rub the skin. If I skin still feels a little dirty than I will peel the skin from the top.

PMSL I have been over here with Woolies for 4 years and I still call it Safeway!
I haven't lived near a 'safeway' for 11 years and still call woolies safeway sometimes! lol
