Mold on lps and record sleeves..HELP

Hi all..
Ok, so my vinly collection finally arrived from theUK...
It has obviously been ina damp environment..
There is white-ish mold spots (to varying) degrees on all records-some 250 or so..
Covers also show mold /damp residue..And smell funky...
So-obviously cleaning is in order-Which I am dreading..
Nitty gritty?
one step liquid or more??
Brushes-so many differing opinions..
ALSO!!!! How dangerous is this kind of mold to one's health?
Should I Lysol the outer sleeves (with the lp removed???
Obviously I will replace inner sleeves.But would like to keep outer ones if poss..
Your help please!!
