Mineral oil on red copper

Will using mineral oil on red Lincoln's make them turn brown? I have a few crusties that have a little red left and do not wish to lose what I do have, but need to get rid of crusties that ar on them. I also have a 1983 d DD that had brasso used on it. Wanted to shoot the seller, but I think after a year of soaking in acetone and other coppers that the look has returned. Wish I had pictures but I don't have a macro lense yet and I have not gotten very good picture results with my stock DSLR lense. Thanks for your input.

    Pure mineral oil will not hurt the color of a red cent.

    Thank you for your input. I just have never used it before so no experience except reading these wonderful message boards.

    Years ago, Lincoln cents were coated with oil to retain their red color.
    Not sure how much it helped, but it didn't hurt.

    PS- always listen to what coppercoins says.
    Some coins are just plain "Interesting"
