Additional Information
Keep away from fire or open flames. Do not throw empty containers into fire.
The spray may soften synthetic resin (e.g., styrofoam) or dissolve paint or coatings — keep away from bags, floors, and furniture.
Tips for effective treatment:
• Apply to the affected area and surrounding skin — the fungus often extends beyond visibly affected areas.
• Continue treatment for at least 1 month after symptoms clear. Symptoms may disappear before the fungus is fully eliminated.
• Keep feet dry and well-ventilated. Wash the affected area daily with soap.
• If other household members have athlete's foot, treating everyone at the same time helps prevent reinfection.
