Most white cloudy spots on Treasure Valley windows are mineral deposits sitting on top of the glass, and those come off. A smaller share have etched into the glass itself, and no cleaner can undo that. Two minutes of testing at your own window tells you which one you are looking at.
Hard water spotting starts as calcium and magnesium left behind when sprinkler overspray or roof runoff dries on the pane. Fresh, it sits on the surface like a film and comes off with a normal wash within days. Left through a couple of Idaho summers, that deposit bonds chemically to the silica in the glass and stops responding to soap at all. That is stage two, and it still comes off with the right abrasive and enough patience. Stage three is etching. The mineral has pulled alkali out of the glass surface and left microscopic pitting behind. The damage is now in the glass, not on it. The fourth thing homeowners mistake for hard water is a failed insulated glass seal — haze or fog trapped between two panes. That one is unreachable from either side, and no product or technician cleans it.
Run these before you pay anyone for a diagnosis. Wet test: soak the pane with a hose and look at it while it is dripping. Surface deposit vanishes under water and reappears as it dries, because the water fills the texture. If the haze stays visible under a sheet of water, the flaw is in the glass or between the panes. Fingernail test: drag a nail sideways across a spot. Deposit has grit you can feel and catch. Etching feels flat. Side test: clean the inside, then the outside. If the cloud survives both, it is not on a surface anyone can reach, which points to a blown seal. Vinegar corner test: hold a vinegar-soaked paper towel on one small spot for five minutes. Lightening means mineral. No change at all points toward etched glass. Skip this one on tinted or filmed windows.
Restoration is not window cleaning with a stronger soap. It is a mechanical process done one pane at a time. A technician tests an inconspicuous corner first, then works the deposit with an acidic gel or a cerium oxide polish and a pad, keeping the glass wet and the heat down so the pane does not stress-crack. Bonded stage-two staining on a single large pane can eat twenty to forty minutes on its own. That is why it gets quoted separately from a standard clean and priced by the pane rather than by the house. Afterward the glass gets a normal wash. Reflekt rinses with 100% pure deionized water and no soap, so nothing is left on the surface to grab the next round of dust — the RainShield finish. Restoration and cleaning are two line items on purpose, not one blended number.
Four situations where hiring Reflekt, or any cleaner, is the wrong move. The haze is between the panes: that is a sealed-unit failure, and a company charging you to attempt it is charging you for nothing. The window is still under a manufacturer or builder warranty: some warranties are voided by abrasive polishing, so get the claim answered before anyone touches the glass. The pane is tempered and heavily etched: tempered glass carries surface irregularity from manufacturing, and aggressive polishing there can leave visible waviness, trading cloudiness for distortion. The sash or frame is already failing: if the wood is soft or the vinyl has warped, restoring the glass polishes one part of a window being replaced in two years anyway. Reflekt does not install glass. When a job lands in this column, the answer on site is a referral, not an invoice.
Reflekt prices standard interior and exterior window cleaning from $199, scaled by pane count, with screens at $50. Hard water restoration is quoted on site, because the only honest way to price it is to test a spot and watch how fast the deposit gives up. Severity, pane size, and how many windows are affected move that number far more than the home's square footage does. Replacing a sealed glass unit through a valley glass shop generally runs several hundred dollars per opening and climbs for oversized, tempered, low-E, or obscure glass, with a full sash or full window replacement costing more again. Treat those as ballparks and get a written glazier quote. The crossover is arithmetic: when a restoration quote approaches half the replacement quote on glass that is genuinely etched, replacement buys new glass, a new seal, and a warranty.
Criteria that work on any company. Ask them to do a test spot before quoting — anyone pricing hard water restoration sight-unseen is guessing. Ask whether restoration is a separate line item or folded into the cleaning price, because a buried price means nobody is accountable for the result. Ask for a before-and-after photo of the same stage of staining, not a general gallery. Ask for a certificate of insurance sent by the carrier rather than a screenshot. And ask what they will not attempt; a real answer there is worth more than a confident one. Where Reflekt is behind: Hunter Stevens and Ethan Seusy started the company in April 2025. Several valley companies have been at this a decade longer and carry far more total reviews. Reflekt has 115+ Google reviews at 4.9 stars and a little over a year of work. If length of track record is your deciding factor, that is a fair reason to hire someone else.

Usually, yes. Deposits sitting on the surface, and even mineral that has bonded to the glass over a few seasons, come off with an acidic gel or a cerium oxide polish worked pane by pane. What cannot be removed is etching, the pitting left in the glass itself after years of untreated exposure. The wet test separates the two: surface deposit vanishes under a sheet of water, etching does not.
Wet the glass and look at it while it is soaking. Mineral deposit disappears under water and returns as it dries. Etching stays visible wet, because the flaw is in the glass surface. Back that up with a fingernail: deposit has grit you can catch, etching feels smooth. If the haze survives cleaning both sides, it is likely trapped between panes, which is a seal failure rather than a stain.
On fresh spotting, often. Hold a vinegar-soaked paper towel against the spot for five minutes, then wipe with a non-scratch pad. The acid dissolves surface carbonate. On deposit that has been baking onto a south-facing pane for two or three summers, vinegar lightens it slightly and then stops. Skip vinegar entirely on tinted glass, applied films, and any stone or metal sill below the window.
Reflekt quotes restoration on site rather than over the phone, because a test spot is the only honest way to price it: how quickly the deposit releases decides the labor. Standard window cleaning starts at $199 and scales by pane count, screens add $50, and restoration is a separate line item on top. Expect a real number after someone has touched the glass, not before.
Yes, if the source stays. Restoration resets the glass, but it does not change what is hitting it. The usual culprit in the valley is a sprinkler head throwing onto the window three mornings a week, so adjust or shield the head first. After that, service interval matters more than any product. Monthly or quarterly cleaning keeps deposits from bonding, which costs far less than restoring the same glass twice.
No. Haze between two panes means the insulated unit's seal has failed and moisture is now inside the sealed cavity. There is no reachable surface, so no cleaner, product, or technique fixes it. The repair is a replacement sealed unit from a glass company, and the existing frame and sash usually stay in place. Check the manufacturer warranty first, since seal failure is often covered for a set term.
