My control variables are
1. water hardness level, as I live in Florida, and I lodged at a Ritz Carlton also in Florida. I'm not, in any way, affiliated with any corporation herein.
2. my eyeglasses with $700 USD Nikon SeeMax Ultimate lenses.
3. my cleaning method (https://www.allaboutvision.com/en-ca/eyeglasses/how-to-clean-glasses/)).
4. and my Nikon micro-fiber lens cleaning cloth.

When I lodged at the Ritz Carlton hotel, I used their liquid hand wash to dab my eyeglasses.

But even when I used different bottles of this hand wash, after rinsing with the Ritz's tap water, my eyeglasses remain smudged. I didn't take the images below, but they resemble my smudges.

When I got home, I daubed some of my Method Gel Hand Soap Refill, Sweet Water (https://methodhome.com/products/gel-hand-wash-refill-sweet-water/) on my Nikon lenses as usual. Then rinsing with my home's tap water cleansed the smudges.
Therefore Ritz Carlton's liquid hand wash appears to be the culprit for my smudges. But I never knew that some liquid hand washes can cause smudges?!!!?! What do you chemists think?
I'm not affiliated, or in any way connected with, any corporation named in this post.

I would be cautious with the solvents you use to clean your glasses. Many lenses are coated. I was in the lab recently and was wearing my normal glasses. A small splash of ethanol hit my lens and caused an irreversible mark. I've never used anything but proper lens cleaning solution as recommended by your optician.
