Cleaning question 1 1

[I’m Rick Jones bitch]

Hope this is the right forum for this, 

I was wondering if any of you cleaning and pressing aficionados knew if sun or dust shadows are defects that a cleaning could help at all? 
Thanks! Pictures available if necessary.

No, sun shadows do not clean off. This is tanning, not dirt. The paper is darker. All the way through. 

I have seen dust shadows that were truly just dust or soot. Those often clean off. Most of the time you will know the difference by looking at the inside of cover.  You see the discoloration on the inside, it's not gong to clean of with dry cleaning methods. It's through the paper and it would take solvents to wash out.

Concentrated UV light alone can also do wonders!

Concentrated UV light does a lot more than wonders.

True, pays for many surgeons' big boats.

Is that an endorsement or a condemnation? Lol

I believe it's mostly a caution.

I know you were asking about shadows in particular, but as a shorthand for whether something can be cleaned or pressed out:

Dry cleaning means using an eraser, and erasers only remove stuff on top.

Pressing makes bent paper lay flat, but will not seal ink that cracked when the paper was bent. If the bend shows white, then white will remain after the bend is flattened.

(Also, if you fill the cracks by touching them with a dark marker, then you are Restoring; adding something rather than subtracting)
