I have seen people suggest using a kneadable eraser to lighten their drawings before painting over the top in oil paint, in a similar way to dusting off excess charcoal.
I would be concerned that the eraser could leave some residue.
Can I have your thoughts on this?

If plasticizers in kneaded erasers could deposit on artwork in significant amounts, in my opinion we would be seeing oil stains while erasing on sensitive papers. According to studies I've seen, among commonly used erasers, kneaded rubber performs best in terms of avoiding particle residue on a fabric surface, better than gum (bread), Pink Pearl, and Vinyl. Kneaded rubber has, however, been shown to cause more color change and alteration of surface on unprotected cotton fabric, but I doubt that's an issue with primed canvas.
So I am posting a link to the Conservation Wiki associated with the American Institute for Conservation (AIC) for works of art on paper. I am presently reaching out to our colleagues in paintings conservation on this matter as I am sure there have been recent studies on this topic as it pertains to the treatment of easel paintings. But here is the link that I mention above: http://www.conservation-wiki.com/wiki/Surface_Cleaning#Kneaded_Erasers
Also....my paintings colleagues have forwarded me this interesting chart. While there are no long term studies associated with aging, etc. some of the information may prove useful to some interested in the immediate effects/composition of various dry cleaning products used on easel paintings.Keulen-2012-Drycleaning-table.pdf
Ron PLEASE feel free to post links where ever you wish :)
