Dr. Beckmann washing machine cleaner is #2 in the Amazon UK Home and Kitchen bestsellers this morning, with De’Longhi coffee machine descaler at #28. If the washer smells musty or the kettle is furred up, which cleaner or descaler should you buy?
The short answer: a dedicated washing machine cleaner for musty drums and detergent build up, a dishwasher cleaner for greasy filters and smells, and a descaler matched to the appliance (kettle, iron or coffee machine), especially in hard water areas.
