Cleaning Stained Wineglasses/Decanters

Most of my good wineglasses are the cheap manufactured Reidels that I steal from various wine festivals I attend. At the end when I'm ready to leave, I walk around & harvest any abandoned wine glasses. So I haven't bought any Reidels in yrs. Works for me.
Over several months, as I leave red wines on the counter overnight, they develop wine & lime stains.
They make me the laughingstock at my weekly wine tastings, even though the glasses are clean & odorless & don't impact my wine tasting. I've tried a number of recommended products to remove the stains. Vinegar/muratic acid/Polident/Eferident/etc to remove the stains. To no avail.
So Dustin recommended to me trying Urnex/Urn & Brewer Cleaner that he uses to clean the coffee containers at Pig+Fig. Active ingredient is Sodium Carbonate. I soaked one of the glasses in a concentrated solution for several days. It came out absolutely pristine, as clean as the day I stole it at the Taos Winter Wine Festival. The second glass is currently soaking in the same vat. So I'm hoping I'll not be the laughingstock at my tasting Wed of Val d'Aosta wines. So thank you Dustin.
So Urnex is a glass cleaner I would heartily endorse. For your glasses & decanters. Maybe even your coffee pots & containers.

As the glass sits in the vat, there's a lot of stringy/flocculent/whispy material that floats around in the solution that has been peeled off the sides of the glass. This stuff is doing its job like a champ.

I've never had a problem with wine glasses, but I never leave on counter overnight with red wine (if not cleaning all glasses at night I dump and add water); But certainly have had buildup on decanters. I periodically use Oxiclean (sodium percarbonate — dry hydrogen peroxide plus sodium carbonate aka washing soda). No long soak needed, I generally fill decanters with solution for 10-15 minutes and then rinse well, they sparkle.

Sodium carbonate. I'd never have thought to try it. I guess they don't call it washing soda for nothing. An elegant and simple solution (pun intended). Thanks for sharing it with us, Tom.

This is a very helpful thread. We have a decanter which has a very flat bottom and and a thin pipe. It is impossible to mechanically clean it, but the soda did wonders.

Thank you all
