Homes & Gardens discusses a glycerin window-cleaning method intended to leave a very thin layer on glass. The quoted recipe uses only two or three drops of vegetable glycerin in about a liter of warm water. Its experts advise working from top to bottom and buffing with a separate clean, dry microfiber cloth.

Use Very Small Amounts When Assessing a Glycerin Glass Method

The article's claims about dust and condensation are expert suggestions rather than a guarantee for every window. Check compatibility with any specialist glazing coating before trying an additive, and avoid leaving a visible film. Careful dilution and removal of excess moisture are central to the described method; applying more glycerin is not presented as a way to improve the result.

The reported window-cleaning recipe relies on dilution and dry buffing, not a thick coating.
