The Jungjun Industrial Ttermes + Five-Grain Exfoliating Soap combination is the best!
These are products I've tried since I started avoiding public baths due to COVID-19.
It works very well. You don't need to soak your body separately; just apply soap to the Ttermes and gently roll it.
It honestly feels as soft as if you had scrubbed off dead skin at a bathhouse.
I highly recommend it!!
