If your washing machine suffers from flaky build-ups, this anti-limescale magnet from Wpro is the must-have gadget for your home. Because it screws onto the tap pipe, it means that the water passes directly through it, so any calcium molecules in the stream are attracted towards the magnet and pulled out. This stops them going further into the appliance and turning to limescale. It softens the water too, and keeps the heating element from becoming encrusted. You can use this accessory with any brand of machine.
