Oxidation removal in Blaine, MN
If it comes off white on your hand, it is not dirt. It is your siding.
The median Blaine home was built in 1996, and siding that age oxidizes: sunlight breaks down its surface into a chalky powder, starting on south and west walls. A house wash cannot fix that, because oxidation is not something sitting on the siding. It is the siding itself.
Oxidation removal lifts the dead chalk layer and brings back the color still underneath. Reconditioning is the step after: a UV-protectant restorer applied over the cleaned surface, so the siding holds its color longer before it chalks again. Neither step can restore pigment that is already gone.

BLAINE SPECIFICS
What oxidation removal means in Blaine
The local conditions that shape how Glass House approaches oxidation removal in Blaine, and the standards it holds to on every visit.
HOMES
Newer homes, built 1990s to 2010s
The median Blaine home was built in 1996, and more than half were built between 1990 and 2019. Newer builds and original 1990s siding often share a street. About 30 years of sun breaks the surface of 1990s vinyl and paint down into a chalky film called oxidation, which streaks when rain runs over it. Newer builds stay easiest to keep clean when growth is washed off before it sets in. Builder-grade vinyl from the late 1990s and early 2000s chalks far worse than the panels made today.
TREES
Oaks, the most plentiful shade tree
Blaine calls oaks its most plentiful neighborhood shade trees and loses hundreds to oak wilt every year. The city is also removing an estimated 1,200 boulevard ash trees because of emerald ash borer. Oak shade keeps roofs and siding damp, which algae and moss need, and oak leaves and catkins fill gutters each year. Dying ash turn brittle and drop limbs onto roofs and into gutters until they are removed. Sunny south and west walls chalk first, while shaded north walls grow algae instead.
WETLANDS
Wetlands and more than 700 ponds
Blaine has more than 700 stormwater ponds and infiltration basins, and the Blaine Wetland Sanctuary covers more than 500 acres of wetland and upland. That much standing water keeps the air around nearby homes humid, so siding, roofs and decks dry slowly after rain and dew. Algae, mildew and moss take hold on surfaces that stay damp, usually starting on the shaded north side. Homes near water often show both problems: algae from damp air, chalk from sun.
COMMUNITY STANDARDS
Community standards for exteriors
Blaine's community standards require corrective action when siding, fascia or roof surfaces are missing, rotting or have peeling paint over 20% of any one side. Algae, dirt and chalky film can hide soft fascia or peeling paint. A clean exterior reveals those problems while they are still small and less costly to repair, well before they approach the 20% mark. Heavily oxidized siding can be fragile, so a signed damage waiver may come first.

HOW WE REMOVE IT
The right product, from the bottom up, judged dry
A regular house wash mix does not remove oxidation. It runs down a chalky wall in streams and moves the chalk around, leaving the wall streaked and blotchy. Oxidation needs a product made for it.
WHAT GOES ON YOUR HOUSE
For removal we use OX-KNOX most of the time, or Clonsol-BC from EacoChem. For reconditioning we use Vinyl Renu Pro from SealItGreen. Carson is glad to answer any question about them.
01
Test a hidden spot
The product is tried first behind a downspout, a shrub or a corner nobody sees. That test proves it is safe and effective on your particular siding before it touches the whole wall.
02
Wet everything down
The wall, the windows and every plant around the work are soaked with water first and kept wet throughout, so any overspray lands on a wet surface and is diluted to the point of being harmless.
03
Apply from the bottom up
We work in sections about 10 feet wide, starting at the bottom. Applied from the top of a dry wall, the product runs down in narrow streams that clean hard where they land, leaving stripes that cannot be blended out. Each section dwells a few minutes and is misted again if it begins to dry.
04
Brush gently along the laps
A soft flagged-bristle brush works along the lap lines, the horizontal seams where one course of siding overlaps the next. There is no hard scrubbing: the chemistry does the work and the brush lifts the chalk. In our experience, products sold as brushless fall short on real oxidation.
05
Rinse low, then judge it dry
The rinse runs top-down at low pressure with a wide fan, carrying the loosened chalk off the wall. Every wet wall looks restored, so the real result is judged only once the wall has dried.
FOR BLAINE HOMES
What to know before your visit
THE SUN TEST
Check south and west
Oxidation shows first on the sunniest walls, while growth favors the shaded north side. A chalky south wall and a green north wall are two problems, not one.
COLOR AND FINISH
Dark walls chalk sooner
Dark colors have more pigment to lose and run hotter in full sun, and flat finishes carry more pigment relative to binder, so both chalk sooner than light, glossier siding.
METAL TRIM
Gutters and trim chalk too
Aluminum gutters, fascia and soffits grow their own oxide layer, a hard, chalky gray film that has to be dissolved chemically rather than scrubbed. Abrasives strip the factory finish and speed oxidation.
UPKEEP
Wash every year or two
Dirt and airborne pollutants on the surface speed the breakdown, so washing every year or two helps. After that, reconditioning is what slows the clock.

Quoted in person by Carson
Every wall is different
Test spot first
Oxidation removal is quoted in person, because the price depends on the material, how far the chalking has progressed and how much wall there is. It costs more than washing the same house because it takes considerably longer. Carson runs the wet wall test and a test spot, then tells you plainly whether it is worth doing.
THE OWNER
The person who quotes your home does the work
Glass House is owned and run by Carson Brenny, with no crews, subcontractors or handoffs. He grew up in Ham Lake, went to Blaine High School and has worked full-time in exterior cleaning for six years. The person who quotes your home is the person who arrives, does the work and walks it with you at the end.
Every job receives the gentlest method that will do the work, because too much force or too strong a mix can cause damage that no cleaning undoes. Every homeowner receives a clear explanation of what is on the house, why the method was chosen and what cleaning can and cannot fix, before any money is spent.
IN CARSON'S WORDS
“It's my neighbors' homes: their biggest investment, one of the places they spend the most time, and where the people they care about most live. It's something everyone should enjoy, and I believe that.”
Carson Brenny, owner

EQUIPMENT AND METHODS
Made-for-it products and a soft brush
Removal: a dedicated oxidation remover applied from the bottom up in sections about 10 feet wide, a soft flagged-bristle brush along the laps and a low-pressure, wide-fan rinse from the top down. Reconditioning: a UV-protectant restorer applied to the clean, dry wall once removal is complete.
BLAINE QUESTIONS
Oxidation Removal in Blaine: FAQ
Can oxidized siding on my Blaine home be restored?
It depends on how much color remains. Hose the wall down and look at it wet: if the color comes back rich, the pigment is still there, and oxidation removal can recover it, with reconditioning to help it last. If it stays dull when soaking wet, the color is gone and no product brings it back. That is a paint or replace conversation, and it is better had before anyone spends money.
Do you serve all of Blaine?
Yes, every neighborhood in Blaine. Glass House is based in Ham Lake, and Blaine is part of its regular north metro service area, so there is no trip fee. Carson quotes, cleans and walks every job himself, wherever in Blaine your home is.
Why does my siding leave white chalk on my hand?
That is oxidation. Sunlight has used up the UV protection in the siding or paint and broken the surface down into a loose powder. It is not dirt sitting on the house; it is the material itself, which is why a regular wash does not fix it and a product made for oxidation does.
Will a house wash or pressure washing fix it?
No. A house wash removes what is on the siding, and oxidation is the siding. A standard wash mix can leave a chalky wall blotchier than before, and high pressure will not remove oxidation but can etch the surface, leave wand marks and drive water behind the panels.
Why does it cost more than a house wash?
Because it takes substantially longer than washing the same house. Oxidation comes off section by section, about 10 feet at a time, worked by hand with a soft brush and a product made for it, then rinsed with care and judged once the wall is dry.
How long does reconditioning last?
Restorer manufacturers claim up to 10 years of protection on a properly prepped wall. We treat that as a best case and not as our guarantee. Walls in rougher shape usually see a few years less, and washing every year or two helps any wall hold its color longer.
