Morrison wrote in 1995: "To my >knowledge, there is no solvent for rubber cement [made from natural >rubber]." Like Jon Derow, I have also had success using hydrogen peroxide for the staining left behind by rubber cement; however, there is a commercial product available specifically for dissolving rubber cement adhesive called "Bestine". It is basically Heptane and is available at artist's supply stores. Before applying hydrogen peroxide, I remove all of the adhesive by swabbing the area with the Heptane using cotton swabs or cotton balls. The solvent is left for a minute or two to soften the adhesive, which is then gently scraped away with the edge of a micro-spatula (if the paper is strong enough) followed by rolling Heptane dampened cotton swabs absorbing the remaining adhesive into the swab. If the paper cannot take scrapping with a micro-spatula, rolling the dampened swabs will also work, but will take more time. Heptane has a great advantages: it does not dissolve dirt and therefore does not leave tidemarks; does not require a fume hood or suction table; and I have yet to find an ink that is soluble in Heptane (although testing first is always wise). I do recommend wearing Nitrile gloves when working with this chemical.
