Repean Dental Cleaner is a dental cleaner applied to your beloved dog or cat's teeth to lift away dirt and remove tartar. It's ideal for pets prone to tartar buildup and senior pets who can't undergo anesthesia. • Repean is an "anti-tartar toothpaste" you make on the spot. It's used by mixing "Repean Powder" and "Repean Water," and utilizes repulsive force to physically detach tartar. • It uses safe and reliable ingredients, so rinsing is unnecessary. • Fragrance-free, colorant-free, and preservative-free. • While strongly alkaline (PH12.5), it's a weakly basic solution that doesn't cause irritation. Made in Japan.
