I'm sorting thru some old prints I made in the 70's while in high school. I must embarrassingly admit that apparantly I didn't get the fix out as there are a few prints with yellow 1/2" circular stains. As well, the edges have begun to brown. Is this normal for edges to brown in older prints? Haven't tried yet, but will a hypo and wash take out the yellow stains? I'll probably do it anyway for peace of mind and before storing them in my new acid free box.

Thanks for any tips,
