Our washing machine cleaning tablets contain sodium bicarbonate and citric acid. They effectively remove dirt and buildup from the inner drum of the washing machine. A single tablet is sufficient to clean the entire washing machine. Usage instructions: 1. Place 1 to 2 cleaning tablets directly into the washing machine drum. 2. Fill the drum with water, run the machine for 15 minutes, then turn off the power and let it soak for 2 to 3 hours. 3. Restart the machine to complete the wash, rinse, and spin cycle to remove loosened dirt and residue. 4. Wipe the drum clean with a dry towel. These tablets also help eliminate odors from both the washing machine and laundry, promoting a fresh and clean washing environment.
