Sponges come in all levels of abrasiveness.
Here in the US at least, there tend to be scratch (yellow/green) and non-scratch (blue/darker-blue). Along with straight scratch pad (pure green) and steel wool (silver metal).
You can grind all day with a non-scratch pad, and all you're really polishing with is the harder bits of gunk you've managed to take off.
Same way you can sand with 220 grit all day and barely make a dent, but hit something with 60 grit and make progress in 5 minutes.
Afaik, Barkeeper's Friend is essentially microgrit in some sort of liquid carrier. If you had the right shaped sand, you could probably add that to something and get a similar effect.
