Since ivory is a very porous material, stains tend to last. You can try to bleach the ivory using lemon juice, but bleaching compromises and weakens the material. Thanks! We're glad this was helpful.
"} 1 Combine ethyl alcohol and water. If dirt and other impurities are still ingrained in your ivory, you will need to clean your object with an ethyl alcohol solution. To create the solution, combine equal parts water and ethyl alcohol in a small bowl and stir to mix. Keep in mind that this is the most aggressive cleaning method, and should only be used on ivory that does not have any fissures or cracks. If dirt and other impurities are still ingrained in your ivory, you will need to clean your object with an ethyl alcohol solution. To create the solution, combine equal parts water and ethyl alcohol in a small bowl and stir to mix.
"} 2 Dip a Q-tip or cotton ball into the solution. After you make the ethyl alcohol solution, dip a Q-tip or a cotton ball into the liquid. Squeeze out any excess, then use a paper towel to blot the Q-tip or cotton ball.
"} 3 Test clean a small area. Ethyl alcohol is a potent cleaner, so you want to be sure to test clean an area of the object before using it on the entire object. Pick out an inconspicuous section of the ivory, then gently rub the ivory with the cotton ball or Q-tip. Dry the area with a small cloth. If there is no discoloration, you will know that the ethyl alcohol solution is safe to use.
"} 4 Use the ethyl alcohol solution section by section. If the spot test went well, clean the ivory object section by section by rubbing the barely-dampened Q-tip or cotton ball on the surface of the ivory. Make sure to dry every section if necessary before moving on to the next one. Work in small patches until you have cleaned the entire object.
"} 5 Dry the ivory with a clean cloth. Once you are done cleaning the object, wipe it down with a clean, white cloth. This will soak up any excess moisture that could damage the surface of the ivory.

Alcohol is nowhere near as strong as acetone for instance, so it should not damage or discolor ABS, but it might affect coatings, so I second the suggestions above — try on a spare keycap, or on a side you can't see. With alcohol, using a simple piece of cloth is enough, brushing your keys with it may be too agressive.
Isopropyl alcohol, (CH 3 ) 2 CHOH, Isopropanol, 2-propanol, or for you chemists out there, IPA, shouldn't damage ABS, PBT, POM, Acrylic, Polyresin, or Polycarbonate, especially if used just for cleaning. Even 99%. There's no need to use the high purity ones for most cleaning purposes, though, as it'll just evaporate faster and make life more difficult for you.
However, it might do Bad Stuff (TM) to decals, pad printing, and that sort of thing. It really depends on what the manufacturer used, and as Ethyl and Isopropyl Alcohol are such common disinfectants, it'd be pretty unprofessional for the manufacturer to make keyboards that can be damaged by a wipedown with that stuff. Dye-sublimation, doubleshot, laser burned, or UV-cured acrylic printing shouldn't be affected.
Sometimes people get Isopropyl Alcohol mixed up with Acetone, as both are sold in drugstores in similar looking bottles and smell funny. Acetone will do terrible things to many plastics.
Side note: Why would there be a concern that people would use Isopropyl alcohol in a drink? Are people that dumb? (apparently, yes). It's hella toxic if ingested and a very different substance (biologically speaking) from, say, the Ethyl Alcohol in Vodka.
