Milky wine glasses explained
It’s very annoying when your wine glasses turn milky-white after being in a dishwasher. Several readers have posed the questions: what can be done to fix milky glasses, and if the answer is ‘nothing’, what can be done to avoid it happening in future?“Modern machines, detergents and glass compositions mean this issue should be a thing of the past.” – Mark Baulderstone
“Firstly, not all glasses are made equal, nor are dishwashers and cleaning chemicals,” he said.
“There has been a significant amount of change in all these areas over the past 15-20 years.
“In the past, it was very common for glasses to go cloudy and milky, due mostly to the alkalinity of detergents and the high heat of the machines, which affect the surface of the glass, turning it milky white over time.
“Sadly, once it goes to this stage you won’t get it back.
“Modern machines, detergents and glass compositions mean this issue should be a thing of the past.”
He said that without knowing the precise circumstances, it’s difficult to say exactly what has gone wrong.
“What I can say, is that all Riedel, Spiegelau and Nachtmann glasses are produced using our own glass composition, which we mix in-house. We do this to ensure consistency and quality. Sadly, this is not an industry standard, but something we pride ourselves on.
“We have been working with Miele in a partnership for many years as they are, in our opinion, the best home dishwasher you can get. All my glasses go through my Miele using the Miele certified cleaning products and my glasses are in perfect condition. Miele have certified all our glasses dishwasher-safe for 1,500 cycles. This covers scratching, breakage and clouding.”
The dishwashing product Miele recommends is its own brand, which can be hard to find, but Baulderstone also recommends Finish Quantum, which I can buy at my local supermarket.
