Spot Cleaner & Stain Remover is made from pure, petroleum-free glycol (100% bio-based activator and stabilizer made from corn), salt (a whitening and brightening agent), lemon & lime (helps dissolve and break down grease), and a very small amount of eucalyptus essential oil. Please note, some pets may be sensitive to eucalyptus. For additional information, please feel free to reach out to our Ruggable Care Team directly.
