Homebrew PCBs

New to the group, have been reading for a few days and getting to try a pcb or two.

I have read on here of the importance of cleaning the cladding and various ways to do that.  Somewhere on here I read of someone who had good success by actually wiping or pre-etching the board prior to transfer.  But now I have been searching for that message reference and cannot find it.

What I was wanting to find out further was whether the poster, after pre-etching the board, then just rinsed in water or if he cleaned the fecl off with something else?

Thanks,
John C.
