Separate salt film from mineral spots
Salt film often creates a broad haze across exposed glass. Dried sprinkler spray or rinse water may leave distinct mineral spots.
USGS classifies water with 121 to 180 mg/L as hard and more than 180 mg/L as very hard (opens in a new tab).
USGS measured total hardness from 5 to 470 mg/L as CaCO3 (opens in a new tab) in shallow Grand Strand groundwater.
Show the provider which panes have haze, spots, or both. Close photos can help the provider assess the buildup.
Ask for an assessment
Routine window cleaning may remove loose coastal residue. Older mineral deposits may need a separate treatment and may not disappear completely.
Ask the provider to test a small area before treating every affected pane.
Protect special glass and finishes
Tell the provider about window film, tinted glass, coated glass, or damaged seals before work starts.
Ask which method and products the provider plans to use on those surfaces.
Define the requested work
State whether the request covers exterior glass, interior glass, or both.
List any screens, tracks, and sills that need cleaning. Include the window count, number of stories, and access limits.
Request salt and hard water spot cleaning
Share the property address, affected panes, glass details, requested areas, and requested timing.
