Glass corrosion

Cliecost

Hi,

It's hard to explain so, sorry if I go on a bit trying to do so.

All my glass goes this weird milky way. It looks like a thin layer on top is melting.

In the picture below you can see it looks like dribbles of something is running down the glass.

I've tried soaking, scrubbing, submerging in a mild acid, having my dishwasher dispense more salt when washing (hard water area), different rinse aid's and nothing works!

It takes about 6 months for the glasses to get to a point where they look permanently dirty and are only fit for children to use lol.

Does anyone know what it is and if it's fixable?

Thanks

Stop putting your glasses in the dishwasher.

Found this online;

CLOUDY GLASSES?
You can determine the cause of cloudy glassware by soaking a glass in vinegar for 5 minutes. If the cloudiness is removed it is due to hard water deposits; make sure the salt reservoir is topped up. Do not worry about over-filling it.
If the cloudiness is not removed, it is a permanent condition known as etching. In this situation, use less detergent and stop pre-washing. Dishwashing detergent needs a bit of soil to work on, otherwise it will tend to foam up.

Why would I do that?! What's the point of a dishwasher if it'd ruin glasses. This is the first time it's happened to me. Loads of people have dishwashers and it can't be happening to everyone in hard water.

Thanks for the post but I've tried vinegar and it didn't work. I tried varying strengths of citric acid and I've even tried a lime-scale remover that burns skin on contact and that didn't work!

I'm just lost for ideas!! Something is coating the glass and I have no idea what to do!

I use tablets so can't adjust amount of soap. I've increased the salt and use the recommended wash cycle.

It's a well known fact that dishwashers erode glass. That's why you should never put lead crystal into them.

Edit: Or your best china. It'll fade the pattern and damage the glaze.

Certain things aren't suitable for washing in dishwashers - that said I suspect different detergents are better/worse. As a hunch the expensive "comes out sparkling everytime" types probably have more abrasive in them to acheive the results so may scratch the glasses more. Mine had this happen to them when I first started, but they don't seem to have got any worse since I started using Tesco cheapo "Daisy" (or whatever they call it this week!) dishwasher tablets. It also doesn't seem to affect pint glasses so whether they are a harder glass to cope with frequent pub washing I don't know.

All my glasses look like that after a while. I just buy cheapo ones from Ikea & replace as necessary.

Same here although the memsahib insists on putting the lead crystal in the dishwasher. Fortunately, as our wine drinking days are long gone, we don't use them very often.

:eek::eek::eek::eek:

If you don't want those glasses, I'll have them !!!

To be slightly more serious - you can put glasses through a dishwasher if you comply with a load of requirements, which really make the whole thing pointless..........

1. They must be labelled "suitable for a dishwasher"

97. They must be done on a low temperature cycle

Because you want your glasses to stop clouding up?

As has been pointed out, it is a well known problem. Wash glass by hand if you want to make sure it doesn't go cloudy.
