Definately!  I use it many times - eventually, you get a "sludge" left in
the bottom of the solution, and it doesn't etch very well any more - that's
when you get rid of it!  Also, it's worth heating your ferric chloride for
faster results each time (can't remember the optimum temperature - someone
else will!)
