Using rinse aid is harmful to sparkling wine.

A tip: if you can, wash your beautiful wine glasses by hand. I know, the dishwasher is a great invention for easing housework. But since the tablets normally contain both soap and rinse aid, it's not a good idea. Yes, because the rinse aid leaves a waxy film that, while giving your glasses greater shine, prevents bubbles from forming in a sparkling wine.
 

Washing wine glasses by hand: motivations

It may sound strange, but the bubbles in a glass, whether it's a flute or a tulip, always start from solutions that are continuously present within the wine, determined by small fragments that settle at the bottom of the glass. They are the starters for the bubbles. If they are absent due to a film of rinse aid, sometimes a sparkling wine may taste still or flat because it doesn't produce bubbles. 
 

The advice is therefore to wash the glasses with warm water and little soap, by hand. Then let them air dry or dry them with a cloth. If you really can't do without a dishwasher, always remember, before putting the glasses on the table, to wipe them all with a cotton cloth so that any waxy film is removed and some small fragments remain to help start the bubbles.
