    Cloudy latte glasses

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Being a time challenged person, I have frequently used the dishwasher (that would be the electrical automatic version) to wash my latte glasses. Recently they have started to go cloudy. I believe this to be a residual calcium scale deposit from the water baked on during the rinse and drying phase of the machine cycle. I reside in Werribee, so who knows whats in the water.

    So how do I get rid of it. Will it be as simple as washing in citric acid? Has anyone seen and resolved this type of thing before. And, yes, I am too tight to go buy new glasses.

    Try throwing them into a bucket of hot water with about 1 tablespoon of nappysan added and leave it overnight.

    Nappysan is good stuff. I use it to clean my showerscreens, portafilters (minus the handle) and baskets.

    Make sure you rinse well with clean water and use gloves when sticking your hand in the bucket. Your hands burn and itch like hell otherwise. :o

    CLR would probably work too.

    CLR contains Hydrochloric acid, Hydrochloric acid was used on our Boema to strip any rubish from it when we first got it and then rinced well. Id say the CLR will work just as well, But the Napisan too is fantastic stuff as well......

    I heard that sometimes the detergents used in Dishwashers also eats at the glass as well, but I might have been mistaken.

    Yes, they can etch glass if theyre not thoroughly rinsed off or the rinse aid in the dishwasher is not working properly. If youve ever noticed painted glasses, the paint fades gradually with repeated applications of dishwashing powder.

    From memory they contain varying amounts of alkaline salts which is pretty nasty stuff. Its like a milder form of caustic soda or "Draino". So very thorough rinsing is probably a good thing.

    You could also try bicarb. Just pour a little into your glass and wipe it inside and out with a sponge/cloth. It doesnt stink like bleach and its eco friendly.

    During the week I tried the 48 hour soak in Nappysan. I would say it was a 25% effective. Then the 48 hour soak in vasalene(sp?), again about a 10% change. Ill move on to citric acid and then bi carb soda this weekend.

    Boris,

    If you use Nappysan make sure the water is fairly hot. Not boiling but as close as you can get (espresso temps ;) ). Always seems to be more effective this way.

    If all of the above treatments fail. Id say your latte glasses are beyond help. New set of Duralex glasses dont cost much more than ten bucks anyway.

    we soak our in bleach in the cafes, or a little elbow grease with detergent and a fine scourer will do it too. Am yet to see a glass which had to be chucked out... (except the broken ones, of course ;).)

    Well nobody can say I didnt try. Every household and most commercial chemicals and even two religous ceremonies refused to budge the deposit. >:( Prolonged soaking and even longer cursings didnt help. ??? So out they went. In the end, my wife was so frustrated with the laundry sink being full she kindly bought me some more. She is a good woman. :)
