My coworker is retiring and gave me her eucalyptus arrangement that was special to her. It was passed on to her when her sister died of cancer. I am not talking about a plant, but rather cuttings. These cuttings are over 15 years old and still look beautiful and still emit eucalyptus scent. I rubbed one of the leaves and the smell was amazing. The cuttings are dusty so I need to learn about how to properly clean them. My coworker suggested picking up a bottle of spray cleaner made for silk plants, but that doesn't seem right to me because this is not a silk plant. I am wondering if anybody here knows how to clean the dust from 15 year old eucalyptus cuttings.
