I have seen a way that people just poured a small amount of etchant over the pcb and rubbed the board with a sponge. I want to know can it work.

It is really a good way which can decrease the waste.

This method is very well. But you need to be careful, otherwises you can simply scratch the protecting mask which is over the copper.
