I have purchased 3 lots of vinyl that were flood damaged. The bad issue is the covers will be pretty much screwed. But the good news is the vinyl can be cleaned. I have used very successfully 3 step process. First, get some bleach and dilute 50%. Use a separate brush for the bleach solution. step one, put bleach solution on the record and spread to cover all of the grooves. let stand for 3-5 min. Then using the same brush, scrub the side. Vacuum off bleach solution. second step- use your normal cleaning solution and brush you use for it and follow your normal regime. Third step, rinse with distilled water.
If you are a steamer (some do and some dont), it works well with the bleach step.
I now use an ultrasonic bath, but have not brought any recent moldy records but i am sure the bleach would work with it also. The bleach will kill the mold on the record and will not hurt the vinyl if you follow your normal cleaning regime and rinse well. I have about 350 records that i recovered this way. Final warning, Throw away the old liner and use a new liner for the record. This is a lot of work, but it will recover them with this method
