Oil stain removal in Blaine, MN
If the spot came back after you washed it, it never left. It is in the concrete.
Oil soaks into Blaine driveways rather than sitting on them, so an ordinary wash cleans only the surface above the stain. That is why the dark spot under the car keeps coming back.
Every stain job starts with a spot test on your slab, and we charge only if we can complete it. Carson Brenny, the owner, does every stain job himself, from the first test to the final flush.

BLAINE SPECIFICS
What oil stain removal means in Blaine
The local conditions that shape how Glass House approaches oil stain removal in Blaine, and the standards it holds to on every visit.
STORMWATER
Runoff flows to the Mississippi
Blaine's runoff flows through storm drains, ditches and a network of more than 700 ponds and basins on its way to the Mississippi River. The ponds are designed to remove pollutants from runoff, but anything hosed into the street, from motor oil to chemicals, still starts down that route toward the river. Oil on a driveway is absorbed and swept up, never hosed toward the storm drains.
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. Driveways poured with homes of that era have had years of drips to soak into the slab.
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.
FRESH SPILL
The first hour matters
The clock matters more than the product. Cover a fresh spill within the first hour with non-clumping clay cat litter or oil-dry, grind it in underfoot so it reaches the oil in the pores, leave it an hour or overnight, then sweep it up. That one step changes the whole job, and whatever remains is then degreased.

HOW WE REMOVE IT
Degrease, dwell, flush, repeat
Oil must be emulsified, broken into droplets that mix with water, before rinse water can carry it away. Our process is degreaser-based, and F9 Double Eagle is the degreaser we use most often.
HOT WATER, WHEN IT IS WARRANTED
Heat thins oil and helps move it out of the pores, and cold water alone does very little against petroleum. A heated machine is available on special request, and Carson will tell you if your stain calls for it. Most jobs do not.
01
Walk it and spot test
Every job begins with a walk-around. We confirm the stain is oil, check the condition of the surface and test the degreaser on your slab before the whole stain is treated. The test shows how the stain responds and how much is likely to lift.
02
Degrease first
Oil repels water-based cleaners, so it always comes off first; otherwise every other cleaner only works around it. If the job also needs organic cleaning or rust treatment, those follow in that order, and acid always goes last.
03
Agitate and let it dwell
The degreaser is worked into the stain with a brush and given real dwell time, the period a cleaner stays on the surface to do its work. That time lets it emulsify the oil, so the oil releases from the pores rather than only getting wet.
04
Flush it out
The emulsified oil is rinsed out of the pores and off the slab. We never let a chemical dry on the surface unless the product specifically calls for it, so each round ends with a thorough flush before the next one begins.
05
Repeat as needed
Multiple applications are normal on oil and are not a sign that anything went wrong. Each round reaches more of the oil held in the pores, and on an old, soaked-in stain, poultice work can follow to draw oil up from deeper still.
FOR BLAINE HOMES
What to know before your visit
LEAKS
Fix the drip
A car that is still leaking will restain a clean driveway, so the most lasting fix starts with repairing the leak itself.
UNTIL THEN
Catch it
Until the leak is repaired, a drip pan or mat under the car keeps oil off the concrete and out of its pores.
AFTER
Give it 3 hours
Keep cars and foot traffic off the treated area for at least 3 hours after stain removal, so the slab can dry and settle.
SPILLS
Keep absorbent on hand
A bag of non-clumping clay cat litter or oil-dry in the garage means a fresh spill can be covered in minutes, while the oil is still near the surface.

Every stain is different
Test first
Oil stain removal is quoted after Carson sees the stain, because the result depends on how old it is and how deep it has soaked in. He runs a spot test and tells you plainly how much will lift before any work starts.
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
WHAT IS INCLUDED
What oil stain removal includes and excludes
Oil comes out in rounds, and more than one round is normal. This is what every oil stain job covers.
INCLUDED
In every oil stain job
• A walk-around to confirm the stain is oil
• The degreaser tested on your slab first
• Degreaser worked in and given real dwell time
• The oil flushed out, as many rounds as it takes
• Poultice work on old, soaked-in stains
NOT INCLUDED
Outside oil stain removal
• Muriatic acid, which etches concrete and does not remove oil
• A promise that decades-old stains will leave no shadow
• Microbial bioremediation, meaning enzyme or bacteria cleaners
• Rust, efflorescence or paint, which require different chemistry
• Stripping, sanding and sealing, priced by Carson in person
EQUIPMENT AND METHODS
Degreaser first, poultice when needed
F9 Double Eagle degreaser, most of the time, applied in rounds: emulsify, agitate, dwell and flush. On an old, soaked-in stain, a poultice (an absorbent carrier that holds solvent against the slab) stays in place long enough to draw the oil back up out of the pores, past where a degreaser stops. A heated machine is available on special request.
BLAINE QUESTIONS
Oil Stain Removal in Blaine: FAQ
Can I hose an oil spill off my Blaine driveway?
Please do not. Hosing oil toward the street sends it to the storm drains, and water does not lift oil that has already soaked into the concrete. Absorb a fresh spill and sweep it up, and leave what has soaked in for degreasing, so the stain is lifted out of the slab instead of spread across it.
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 oil stain keep coming back?
Because it never left. Concrete is a network of tiny channels, and oil soaks down and outward into them within the first 30 to 60 minutes. Washing cleans only the top, since petroleum does not dissolve in water. As the slab dries, the oil below wicks back up and the shadow returns. A degreaser emulsifies the oil so it can be flushed out.
Can you remove a stain that has been there for years?
Usually a good deal of it. Carson will want to see the stain before saying how much will lift, and the spot test confirms it. On an old, soaked-in stain, substantial improvement is the realistic result, and a shadow may remain permanently. Poultice work reaches deeper than a degreaser alone, but no method makes a decades-old spot disappear.
What do you use on oil?
F9 Double Eagle degreaser, most of the time. It emulsifies the oil so it can be worked in with a brush, left to dwell and flushed out, and most stains take more than one round. On old, soaked-in stains we also use a poultice, which holds solvent against the slab long enough to draw oil up out of the pores.
Can I seal my driveway afterward?
Yes, once the oil is out. Sealer will not bond to oil, so sealing over an active stain leads to fisheyes, dull spots and peeling, and we will not seal over oil that will not come out. Sealing is its own project, priced by Carson in person, and a sealed surface stays off-limits for up to 96 hours while it cures.
