A Homes & Gardens writer describes using a steam cleaner with a squeegee attachment on dirty windows. The article favors a dull, dry day to avoid rapid drying and notes that mineral-rich tap water can leave residue. The appliance's own instructions should decide the permitted water type and whether its glass attachment is appropriate.

Check Water and Steam Settings Before Cleaning Window Glass

Use only a setting and technique approved for the glazing, particularly where heat differences or specialist coatings may matter. Keep a clean lint-free cloth available for edges and remaining moisture. The article warns against excessive steam; adding more heat is not the same as improving cleaning. Test the supported method cautiously instead of treating all glass as interchangeable.

The tested approach uses a glass attachment and controlled steam, with attention to mineral residue.
