Act quickly! Get the LPs out of the sleeves and cleaned. The mold you see is eating the vinyl and there is no recover from that, but you can halt the process so more damage is not done.
Bleach will kill mold, but you need a cleaning solution to remove the residue. Any of the better vinyl cleaning fluids (Walker Prelude, AIVS, Disc Doctor) will be you SECOND step in cleaning.
Your FIRST step can be a 20% bleach solution with water, followed by a thorough rinse, followed by cleaning with one of the cleaning fluids mentioned. Be sure to clean the label and the center hole where mold spoors may also be hiding and can cause a recurrence. (Use a Q-Tip style cotton swab to clean inside the center hole.)
Only after killing the mold on ALL your LPs with the bleach solution and rinse, should you go back to the lengthier task of cleaning each LP. It is important to first stop further damage from the mold continuing to feast on the vinyl grooves of your LPs.
For the record jackets, I've used a combination of 20% bleach with a two tablespoon of TSP per gallon of water. Use a sponge, wring it out to just damp, and wipe down all exterior and interior surfaces of the jacket. (CAREFULLY check a small section of the outside jacket FIRST to be sure this solution is not going to adversely affect the jacket.) Insert something inside the jacket to hold it open for 24 hours until it thoroughly dries.
Good luck!
