Erasing OTP's and EPROMS by heat?

I once heard that if you heat up an EPROM in an oven to a sufficient
extent then the leakage of the cells increase to the point that the
stored charge is discharge and the EPROM is effectively erased. Would
this really work? The reason I need to know is that I just bought 1000
OTP microcontrollers for a very good price from China but every one of
them is already programmed with 00 to FF sequentially for the whole
EPROM space. If I can possible save them, then good but otherwise they
are just rubbish now and I have lost my money :-( The part number is
MC68HC705J1ACP.
