I just inherited a massive stack of records (~75 classic LPs), and need advice on a mass-cleaning.

Like the title alludes to, I just received a huge box of classic records from my parents (I can share some pics if you guys are curious). Many are in need of a major cleaning though, and I was thinking of having a mass cleaning session.

Any advice on how to go about giving so many records a deep clean? Your help is much appreciated.
