6-in-1 Action - Dissolves hair - Eliminates limescale - Removes dirt/residues - Eliminates bad odours - Prevents blockages - Kills 99.9% bacteria Deep cleans and protects your washing machine by removing clogged up hair, dirt, limescale and bad odours. Clogged up hair (both human and pet hair) is a common cause of washing machine breakdown and bad performance: a normal wash with detergent alone does not remove clogged up hair. Say hello to the only washing machine cleaner that dissolves hair whilst also eliminating dirt, limescale, detergent build-up, bacteria and smells. Regular use will protect your washing machine, whilst extending its life and enhancing performance. We recommend using every 1-2 months to prevent blockages and maintain freshness.
