Precautions & Patch Test Guidance
Use exclusively plain white chalkboard chalk; colored chalk contains pigments that will transfer dye onto white cotton collars.
For any topical preparation, always conduct a 24-hour inner-arm skin patch test first. Informational traditional wisdom only—not medical advice. Read full Health Disclaimer .
