DON'T use vinegar in your washing machine
Today we had a service call from our favourite Miele Senior technician. He said to NEVER use vinegar in the washing machine or the dishwasher Yes, it shines the stainless, but he said it totally eats and rots the rubber hoses and seals. He went on to say that they can always tell the machines that are used with vinegar. He says hoses and rubber seals and parts many times just crumble in his hands, when service is performed!
He said yes it is chemical free, but it is NOT good for the machines. Liquid fabric softener is 100% safe, when used as directed & with normal use...it does NOT build up or gunk the machine (especially if a regular clean machine cycle is done).
