Things You'll Need
Instructions
Work over the figurine gently with a soft, dry paintbrush. This is a very good way of dislodging accumulated dust from hard-to-reach areas such as the nooks and crannies in headdresses and facial features.
Wet a cotton wool bud in mineral water and apply it to the more resilient areas of dirt. Be careful to not apply pressure to fussier details such as inlaid eyes or finely carved fingers. Once you've finished, turn the cotton wool bud around and use the dry end to remove any excess moisture --- water that sinks in to the ivory can cause cracks.
Turn your attention to any heavily stained areas. If they are in a finely carved part of the figurine, you might want to work once more with a wet cotton wool bud. Otherwise, use a small segment of soft, dampened sponge. Pause and dry regularly to gauge the effect of your work --- you might, after all, decide that you don't want your ivory to look too new.
