Actually bodies, organic materials in particular are shockingly durable when it comes to acid. Contrary to the old legends of the mob melting people in sulfuric acid you’d actually want strong bases like Hydroxides to do anything to flesh (acids would only ruin bones, and teeth and metals.)
My university uses an enormous tank of Hydroxide to melt down diseased carcases and other biological research waste (the resulting brown slurry which is pumped through a sprinkler over a fallow field.)
To note, if you ‘were’ experiencing vast rains of acid anything like the game you are NOT going to survive. Most plant and insect life (excepting oddball extremophiles like Sphagnum moss, certain fungi and alga species) will simply die from pH imbalances causing a food chain collapse.
Not even considering the effect of breathing clouds of acidic steam wafting around as the landscape broils away in exothermic reactions. Our nervous system is heavily reliant on calcium ions so, while you wouldn’t melt per-say, you would die an excruciatingly painful death as the calcium is leached from your blood and your neurons begin misfiring like mad.
Scavengers like wild dogs, zombies, rat swarms, crabs, and even stranger things would be more appropriate (and interesting) corpse disposal.
