Working with copper - I've already degreased this plate as part of standard preparation. After etching an aquatint & soft ground, I did some heavy burnishing. Is it necessary to degrease again before the next inking? I normally would clean off with California wash.

(First learned etching with a wonderful, but slightly flighty instructor, who didn't have us file, degrease or polish at all. have been tryingto fill in my gaps with a second instructor, the communal wisdom at my local workshop, and the internet) :clear:

I've never heard of "California wash."

To me, degreasing is merely plate-cleaning, which I do before I print, and afterwards as well. I use whiting mixed with a little ammonia and water.

I normally only degrease when I am going to be applying a ground of some type so that it will adhere properly. Before inking I make sure the plate is clean but I have never degreased it before inking. I suppose that I might if I was using water based inks.

I too have never heard of California Wash. A quick google seems to indicate that it is a water soluble solvent. Is that correct?

California Wash is pretty heavy duty!!! why not OMS or something less carcinogenic?

who didn't have us file, degrease or polish at all. interesting. I consider degreasing something that is not greasy as superfluous. My personal opinion is that shininess, not greasiness, is the culprit for strikethrough.
