Just be careful wintergreen oil is toxic. I found this on WebMD. I didn't use gloves but I did try to stay out of the steam. After I removed the parts I washed them with soap and water.
Wintergreen is safe in the amounts found in foods, and seems safe for most adults when used as a medicine.
The oil is UNSAFE to take by mouth. Taking wintergreen oil or large amounts of wintergreen leaf can cause ringing in the ears, nausea, vomiting, diarrhea, headache, stomach pain, and confusion.
When applied directly to the skin, wintergreen oil can cause skin irritation.
Special Precautions & Warnings:
Children: Wintergreen leaf and oil can be poisonous for children. Taking 4-10 mL of wintergreen oil by mouth can be deadly. Don’t even use wintergreen oil on the skin of children less than 2 years old. Pregnancy and breast-feeding: Wintergreen is safe in amounts found in food, but there's not enough information to know if it's safe in the larger amounts that are used as medicine. Don’t take it by mouth or put it on your skin, if you are pregnant.
If you are breast-feeding, don’t take wintergreen by mouth or put it on your skin. Wintergreen products might be toxic to nursing infants. Stomach and intestinal inflammation: Taking wintergreen by mouth might make these conditions worse. Salicylate or aspirinallergy, asthma, or nasal polyps: Wintergreen might cause an allergic reaction in people who are allergic to aspirin or other salicylate compounds, or have asthma or nasal polyps. Use wintergreen with caution if you have one of these conditions.
