Am I washing my glasses wrong??

I expect that Alan and Andy may be correct that the microfiber drying cloth is the culprit. Trying washing as usual, rinsing really well (with RO or distilled water, if you have hard water), then air-dry and compare results.

I agree it’s your towel. The towel below will solve your issue.

I have discovered that microfiber cloths suck. I got a 100% linen dish towel that was made in Portugal from either Pottery Barn or Williams Sonoma (I forget which now). Works like a charm to dry all my stemware and not cause what you’re experiencing.

I’ve switched from linen to Grassl microfiber from Chris Freemot. Linen get wet too fast and wet linen is heavy. My Grassl glasses hate weight/resistance. Different strokes.

Curious as some here mention using soap… does this not effect the taste of the wine as it leaves a residue? Especially the generic dawn type etc…

I never use any soap - just warm water and a Riedel polishing cloth after air dry - works like a charm!

Cheers.

Soap and hot water = clean. Regardless of what you are cleaning. Proper rinsing leaves no residue. I personally believe that residue left behind is from not getting glass clean enough in the first place.

Microfiber comes in dozens of different types, just like cotton towels. Diff weaves, grams per square inch, length of nap, and different poly blends. Not that we need to go that into depth.

Obviously, the towel needs to be clean to not re-contaminate the glass.

The Grassl microfiber has zero nap. Zero streaking. Zero spotting.
