Lye and water
Can buy lye at any home depot/lowes type store. Buy in cash.
Mix up a bunch of lye and water in a plastic container (55 gal drums work). Submerge the body in the mixture. Break down body if you have to.
Mix periodically. After a few hours, should have a nice human-being slury. Dump in woods, sewer drain, etc. All the evidence is gone by that point.
I don't think it would destroy bone, and "slury" would be more like porridge in my opinion. Maybe something that can be periodically flushed down the toilet. Any large acid or base dump into the sewer system would probably be investigated though, so have to dilute a lot or change the PH more neutral.
Doesn't completely destroy bone, but makes them very brittle. To be extra careful you could strain out the bones and crush em up.
Slury if you use enough. Since it's just lye and water, it's pretty easy to make a bunch.
They would get investigated if it was somehow discovered. Even then, the case woulud go cold before it was even opened. Unless you added in a shit load of your own DNA samples into the slury before you dumped it.
