There are a few different ways that you can clean ivory gun grips. However, whichever method you choose, make sure to use caution and avoid any contact with the metal parts of the gun, as this could cause the ivory to corrode.
One option is to use a gentle cleaner like soap and water. Be sure to rinse off all of the suds completely, and then dry the grip with a soft cloth. Another option is to use denatured alcohol on a Q-tip or a soft brush. Again, make sure to completely dry the grip before putting it back on the gun. And lastly, you can also use saddle soap. Just be sure to follow the instructions on the package carefully, and again, completely dry the grip before using it.
Use a soapy cloth to clean the gun grips. Rinse with water and dry with a cloth. If needed, use a light coat of furniture polish to help keep them looking new. Avoid using harsh chemicals or cleaners as they can damage the gun grips.
