They all probably have the same source, unfortunately. About cleaning... I can't help you with magazine scans, sorry, it's too advanced for me too. But if you're going with the second method, then leveling itself should be enough (I'm sorry, I don't know how good you're with graphic programs so I'll try to write it like for a total beginner, sorry if it offends you). In Photoshop, go to Image > Adjustments > Levels. In Gimp, it's Colors > Levels (I think? I'm sorry, I've never used English version of Gimp). There you have a graph connected to input levels, and a bar where you can change output levels. In input levels case (which is the one that should be used), you have three arrows. It shows you the distribution of pixels on your page (how much black/gray/white there is on your page). And well, all you have to do is to change arrows' position. It depends on the page, so try experimenting. Also, in magazine's scans even after the best leveling, there may be some white pixels on the black areas. In this cases, there are some methods, like filters (some people use diffuse filter) or playing with curves. There's always Denoise program which seems to be quite useful, but I've never used it. I'm sorry, that's all I know in this topic u_u
