Questions about window stain removal and interior window cleaning
How are hard water stains removed from glass?
Sureclean describes hard water stains as dissolved minerals like calcium and magnesium that remain on glass as white deposits after water evaporates, and states that hard water stains can be removed by applying a mixture of equal parts white vinegar and water to the affected areas. This method fits mineral residue on glass and is separate from exterior or high-rise access work.
How is streaking reduced during window cleaning?
Sureclean states that squeegee blades should be wiped with a clean, dry microfiber cloth after each stroke to prevent streaks. This applies to finish quality during glass cleaning, and it is less relevant to questions about exterior access or high-rise cleaning because those services are outside the stated scope.
