I don't think 60 degrees celsius is enough, let alone any residue chemicals, the salt, the rinse aid etc. etc. is healthy. And on top everything smells of fish

I don't think 60 degrees celsius is enough, let alone any residue chemicals, the salt, the rinse aid etc. etc. is healthy. And on top everything smells of fish for weeks? Doesn't sound like a hack to me. Just use your oven, that actually is healthy and foolproof.
