I think you might be hosed. I had a similar event occur in the 70's and the records were trash. Mold gets into and beneath the grooves and wrecks vinyl. If it is surface only mold they might be salvage worthy.
I use the SOTA lp record cleaner, Mofi Enzyme and Record Wash, then LAST and mofi sleeve. Works for me. I sometimes find some Salvation Army or other scores just will not clean up although overall the lp cleaner and cleaners have been a fantastic investment.
I would recommend you contact Mike Fremer at Analog planet as perhaps the new ultrasonic cleaning machines might be up to the task or perhaps a poster who owns one can chime in.
Good Luck but fear you may be in for some long term replacement. please do a follow-up post on how this works out.
