Dr. Beckmann Original Service-It Washing Machine Cleaner has a unique formula with activated carbon that releases and captures residues which are then washed out effectively in one treatment. Residues, dirt and limescale can harm the functioning and performance of the washing machine. This formula cleans to remove dirt build-up, detergent residues and limescale from non-accessible parts inside the machine like drum and pipes. It also provides protection and maintenance with corrosion inhibitors that protect the metal parts; whilst special conditioning ingredients keep the rubber seals elastic. Why activated carbon? Active Carbon is a special ingredient that acts like a magnet to absorb dirt and odours to leave your machine cleaner and fresher. Warning: Keep out of reach of pets and children. Always read packaging before use.
