You're trying to find out what's good for murder cleanup, I see. Well for starters, hydrochloric acid is basically muriatic acid 😅 it's used for unclogging pipelines and toilets in an industrial use buuuttt it can be used to wipe out fingerprints in a crime scene so that's why the cleaners have that. And if you're looking to dispose of a body, I'd recommend sulfuric acid and hydrofluoric acid for the job so you don't leave a trace UwU but it's easier to melt bodies with HF then mix in a bit if calcium carbonate in it after you've melted everything so it's easier to flush down the toilet or drain UwU
This is my murder insight. Thank you for coming to my Ted talk 🤣
Now my question is. Why are you plotting murder in a hardware shop???
