After about 1 or 2 minutes you’ll notice that you can see some board through the copper. Frequently check until all of it is gone, when your artwork is clean and clearly visible get it out of the bowl and rinse it with water. Remember we don’t want to leave it in the solution for too long or it will begin diss olvingtheprotectedcopper. Congratulations, you just made your own Printed Circuit Board.
