Take a damp cloth & use mixture to clean the drum, seal, door & tray
Add 450ml cleaning vinegar to the drum
Put machine on a hot wash (60°c+)
When the machine stops, open door & leave it for a while (overnight is cool) your place might smell like a kombucha factory at first, but it will pass
This will help move limescale from your machine like a dream! Vinegar is acidic. Don’t use on natural stone (like granite or marble quartz), unsealed grout or waxed surfaces. Test on an out of sight area. Dilute if you’ve got any worries. Wear gloves!
