7 specialty stain services
Every major stain type gets its own breakdown, and process.
June–October
This is our stain-removal service season
Process-specific
Different chemistry, dwell, abrasives, and tools by stain type.
If washing did not solve it, it may be a stain problem, not a cleaning problem.
These stains are common across Minnesota, and each one needs a different approach if you want the result to be safe, honest, educational, and worth paying for.
STANDARD CLEANING VS SPECIALTY STAIN TREATMENT
Not every dirty-looking surface needs the same kind of approach.
Standard cleaning services are for organic growth like algae, black algae, moss, mildew, lichen, cobwebs, and routine environmental buildup. Specialty stain treatment is for the issues that keep showing through because they need different chemistry, different dwell times, different abrasives, and often more labor-intensive processes.
Standard cleaning
Best for organic buildup and routine maintenance. This is where services like House Washing, Roof Washing, Concrete Washing, and Window Cleaning usually live.
Specialty stain treatment
Best for hard water, iron or rust, oil, oxidation, efflorescence, graffiti, and construction debris. These issues need a more exact diagnosis and a more exact process.
FEATURED STAIN
Hard water staining is mineral buildup left behind by repeated water exposure, often from irrigation, well water, nearby water sources, or repeated spotting on glass and exterior surfaces.
What it is
Mineral spotting that can move past simple surface residue and toward more stubborn staining or even etching over time.
What causes it
Sprinkler overspray, well water, lake water, irrigation patterns, and any repeated mineral-rich water source drying on the same area.
Who it is for
Homeowners seeing visible spotting, dull glass, or mineral staining on windows or other exterior surfaces that ordinary washing has not corrected.
What we do
Glass House uses stain-specific chemistry, controlled dwell time, #0000 steel wool where appropriate, razor work when needed, and follow-up cleaning to remove or improve mineral staining as far as the surface realistically allows.
Why Glass House is trusted
Hard water staining on glass is one of the clearest examples of where experience matters. The wrong approach can waste time or create risk. Glass House treats it with a more precise process than most companies are willing or able to explain publicly.
FEATURED STAIN
Iron staining, often casually called rust staining, is very common in the North Metro and often shows up in orange streaks or patches on siding, concrete, masonry, and other facades.
What it is
Orange or rust-colored mineral staining that can look like the surface itself is failing, even when the main issue is external iron-related contamination.
What causes it
Well water, irrigation overspray, metal runoff, fertilizer minerals, and repeated exterior water exposure are all common contributors.
Who it is for
Homeowners with visible orange staining on siding, concrete, masonry, or facades who want a safer and more effective answer than routine washing.
What we do
Glass House treats the staining with chemistry chosen specifically for iron-related discoloration and works it in with the right level of agitation for the material underneath it.
Why Glass House is trusted
Iron staining is one of the most common North Metro problems, and Glass House treats it as such. We understand the likely causes, how to talk about prevention, and how to set more honest expectations when the source is still active.
FEATURED STAIN
Oil stains sink into porous concrete, which is why they are so frustrating and why they often need more than just a pressure wash.
What it is
Hydrocarbon staining that penetrates concrete and can remain visible well after the top of the surface looks cleaner.
What causes it
Leaking vehicles, shop or service use, repeated drips, and long-term untreated oil exposure.
Who it is for
Homeowners with stained driveways, garage aprons, or parking areas who want to improve appearance and reduce how neglected the concrete looks.
What we do
Glass House uses absorbents, degreasers, chemistry, agitation, heat, and follow-up methods based on the age and severity of the stain. Results can vary, especially on older stains, but the goal is meaningful improvement.
Why Glass House is trusted
We do not pretend old oil stains behave like normal dirt. The process is tailored honestly and expectations are set like a professional, not like a salesman.
FEATURED STAIN
Oxidation commonly shows up on vinyl siding as a white, chalky, weathered look, but it can also show up on other coated and finished exterior facades throughout Minnesota.
What it is
A chalky, faded, weathered-looking residue tied to finish aging rather than simple dirt.
What causes it
Sun exposure, coating weathering, age, lower-quality finishes, and long-term exposure to the elements.
Who it is for
Homeowners seeing faded, chalky, or weathered siding — especially vinyl siding — who want to improve appearance before deciding they need full replacement or repainting.
What we do
Glass House uses oxidation-specific chemistry and a finish-aware approach that respects vinyl and other facades more than high-pressure cleaning would.
Why Glass House is trusted
Oxidation removal is one of the easiest services to oversimplify. We approach it with more education, more realism, and more respect for the finish condition than most cleaners do.
FEATURED STAIN
Efflorescence is the white deposit that shows up on masonry and concrete when water carries salts to the surface and leaves them behind.
What it is
A salt deposit on brick, block, stone, mortar, and concrete surfaces that often looks like white powder or streaking.
What causes it
Water movement, soluble salts in the material, and evaporation at the face of the surface.
Who it is for
Homeowners with white staining on masonry, retaining walls, brick, concrete, or other hardscape features who want both the deposit addressed and the moisture story understood.
What we do
Glass House removes the visible deposit with a masonry-aware treatment plan and encourages the moisture source to be corrected first or as soon as possible whenever practical.
Why Glass House is trusted
We do not chase short-term cosmetic wins at the expense of long-term honesty. If water movement is part of the problem, we are going to tell the client that directly.
FEATURED STAIN
Graffiti is unwanted coating on a surface, and the best removal plan depends on both the marking itself and the substrate underneath it.
What it is
Spray paint, marker, or other vandalism-related coating on masonry, signage, facades, and exterior surfaces.
What causes it
Vandalism is the direct cause, but the severity of the problem changes based on how porous or delicate the affected surface is.
Who it is for
Homeowners, HOAs, and property managers dealing with unwanted markings on brick, concrete, signs, painted walls, or other exterior materials.
What we do
Glass House uses dedicated sprayers, stain-specific chemistry, and substrate-aware agitation so the removal process stays targeted and as safe as possible for the surface underneath.
Why Glass House is trusted
We explain up front that some porous materials may still show shadowing or ghosting even after strong removal. That honesty matters, and it is part of why clients trust us to approach difficult surfaces the right way.
FEATURED STAIN
Paint, adhesive, caulking, sap, and hard debris on glass need a more detailed process than routine window cleaning.
What it is
Post-construction or post-installation debris bonded to glass that affects the clarity and finished look of the pane, as well as other debris that is adhered to the glass, requiring a razor to remove.
What causes it
Building, remodeling, installation, paint work, adhesive use, caulking, and delayed cleanup around new or recently worked-on glass.
Who it is for
Homeowners, builders, and installers who need post-construction debris removed from glass safely and professionally.
What we do
Glass House uses detailed prep, specialty tools, razors in expert hands, and glass-specific processes that protect the pane while working toward a perfect finished result.
Why Glass House is trusted
Using razors on glass is not the issue — using them poorly is. Glass House has more experience than most, along with specialty tools and techniques that protect the glass while delivering a cleaner finish than general cleaners can usually offer.

FAQ
Questions people ask before scheduling a stain treatment.
The stain FAQ helps readers understand what counts as standard cleaning, what counts as specialty treatment, and how to choose the right stain page quickly.
What is the difference between standard cleaning and stain removal?
Standard cleaning is for organic growth such as algae, black algae, moss, mildew, lichen, and cobwebs. Stain removal is for issues that need a more specific chemistry-driven and labor-intensive treatment plan.
Which stain types do you treat?
Glass House treats hard water stains, iron or rust stains, oil stains, oxidation, efflorescence, graffiti, and construction cleaning / hard debris issues on glass and other surfaces.
Are all stain-removal results identical?
No. The age of the stain, how deeply it has set, what surface it is on, whether the source is still active, and the condition of the material all affect the result.
How do I know which stain page I need?
If the issue is mineral spotting on glass, start with Hard Water Stain Removal. Orange staining usually points toward Iron Stain Removal. Chalky siding points toward Oxidation Removal. White salt deposits on masonry point toward Efflorescence. Graffiti and construction debris have their own pages.
When do you offer stain removal?
Stain Removal is offered June through October.
Can stain removal still be worth it if the source is not fixed yet?
Sometimes yes, but the page should be honest that some stains will return if the source — such as irrigation overspray, moisture movement, leaking oil, or coating failure — is still active.
Start with the symptom
The hub is written to help readers choose the right page based on what they are seeing, not based on technical terms they may not know yet.
Not every problem is a stain
If the problem is mainly organic buildup, the washing pages may be a better fit than the Stain Removal cluster.
