Just happened? Do this first
- Judge the damage first: light browning may come out, but charred or deep burns usually can't.
- Test any bleach or hydrogen peroxide on a hidden spot first.
- Work gently; harsh tools can strip the finish.
- Wear rubber gloves and ventilate when using strong chemicals.
A scorch on concrete, whether a patio slab or garage floor, has changed the surface itself, so it isn't a film you can simply wash off. Fresh light browning sometimes lifts with a gentle scrub, but the deeper the mark has gone, the less cleaning can do. Check whether the surface is sealed or treated first, because a water repellent can stop cleaners from reaching the concrete.
A fresh burn stain on concrete often responds to a few gentle rounds, so you don't need to push harder yet. Scrubbing harder rarely helps and can dull the surface, so keep the pressure light and let the cleaner work. If it's still dark after several tries, that's the point to bring in a pro rather than keep going.

Step by step
Step 1 of 6
Judge how deep the burn goes
Look at the mark in good light and decide whether it's light browning or a charred, deep burn. Light browning may come out with a gentle clean, but a deep burn usually can't be removed and may need professional repair.
Careful. Sanding, steel wool or bleaching can strip the finish, so don't reach for them to speed things up.
Step 2 of 6
Test the cleaner on a hidden spot
Pick the gentlest method that could work and try it on a small, out-of-sight area first. Let that patch dry and check the color and surface before you treat the stain itself.
Tip. Choose a corner by a wall or edge where a small mark won't be noticed.
Step 3 of 6
Brush off the loose ash
Dry-brush the stain with a stiff fiber brush to lift loose soot and ash. Sweep the debris away before you add any water so it doesn't smear into the concrete.
Step 4 of 6
Soak the concrete before cleaning
Saturate the stained area and the concrete around it with water. Keep it wet until you start scrubbing so the cleaner stays on the surface rather than soaking in.
Step 5 of 6
Scrub and rinse thoroughly
Scrub with a mild detergent or kitchen cleanser and a stiff bristle brush, working one small section at a time. Rinse each section thoroughly with water before you move on to the next. On a large, flat area you can use a pressure washer, but stay at or below 400 psi with a 25 to 50 degree fan tip held at least 12 inches from the surface.
Step 6 of 6
Check the mark once it's dry
Let the concrete dry completely and look at the stain again in good light. If a shadow is left behind, the poultice described in the set-in section below is the next step; otherwise you're done.

Best products for scorch on concrete, brick & driveways
Choose a proprietary masonry cleaner made for that stain type over a general all-purpose cleaner, and follow its label exactly. Test it on a hidden spot before you use it on the mark.

Finished the steps? How does it look?
Nice work. Let it dry completely and check it again in good light. Here is what done looks like:
How to tell it's really gone →A faint mark usually needs one more round, not a stronger product.
If the stain was already dried or set, the method changes.
Old, dried or set-in stains →When to call a professional →How to tell it's working
A healthy result shows the edges of the burn fading a little with every pass, and the rinse water running lighter each time. Let the slab dry completely before you decide, because a damp patch can mislead you. If the mark hasn't moved after a full cycle, the scorch has likely set and the set-in notes apply.
What changes for yours
Adjust for your concrete, brick & driveways
Sealed concrete
A sealer or finish on top of the concrete is the first thing a harsh tool will remove, so keep the scrub light. Use the stiff bristle brush with a mild detergent and rinse each section before you move on. Let the brush do the work rather than adding force.
If the shine dulls or the sealer starts to lift, stop scrubbing and assess the damage before you try anything stronger.
Stamped or colored concrete
A strong cleaner can lift the color or dull the pattern on a decorative finish, so the hidden-spot test matters more here. Start with the mildest step and check the test patch carefully before going further. Skip the poultice unless the test area looks unchanged.
If the color lifts or the pattern looks different in the test patch, stop and have a professional look at it.
Concrete steps and edges
Steps and edges hold dirt and water in their corners, so the soak and scrub take more time there. Work one tread or edge at a time and rinse it fully before you start the next. Brush toward the lower side so the rinse water carries the residue off.
Check the vertical faces as well as the flat tread, since the mark can look different on each.
Garage floor
Garage floors take the most heat from grills, heaters and hot parts, so burns there are often deep and charred. Judge the damage first, since a deep mark usually won't clean out. If it's light browning, the same gentle steps apply to the whole floor.
Clear the space so you can soak the whole area evenly, and rinse before the floor dries.
Concrete countertop
A concrete countertop is sealed and sits where you prepare food, so the test on a hidden edge matters even more. Keep the scrub gentle and rinse fully so no cleaner is left on the surface. A deep scorch on a counter usually can't be cleaned away, so judge it first.
For the full routine on counters, see the Countertops guide.
Old, dried or set-in stains
An old burn that has sat for weeks is harder than a fresh one, because the damage has had time to settle into the concrete. Start with the gentle scrub and rinse, and move to a stronger approach only if a shadow is still there. Older accumulated stains need stronger methods, and each one carries more risk of damaging the surface.
Once the area has dried, look at it again in good light before doing anything else. If the mark is still there, use a poultice: mix talc, whiting, fuller's earth, diatomaceous earth or clay with the right solvent, and spread it at least 1/8 inch thick. Cover it with plastic for 24 hours, let it dry, then scrape or brush it off and repeat as needed.
A proprietary cleaner made for that stain is usually a better bet than a homemade mix. Light marks often come out, but a deep or charred burn can leave permanent discoloration that no method will fully reverse. If it's still visible after a few rounds, a professional repair is the realistic answer.
Vinegar, baking soda, peroxide and more
Do home remedies work on scorch on concrete, brick & driveways?
Most household remedies you'll find online are built for fabric or stone, not concrete. Water, a mild detergent and a stiff brush are enough for light browning. The others either don't suit concrete or aren't needed for this mark.

What makes it worse
Mistakes to avoid
Don't mix bleach with ammonia
Bleach and ammonia release a toxic, lethal gas when they meet, so never combine them. Rinse the area with water and let it clear before you try a different cleaner.
Don't guess at an unidentified stain
Stronger chemicals on a stain you can't identify can create marks that are harder to remove. If the mark doesn't look like a burn you recognize, have a testing lab identify it before you use anything strong.
Don't scrub a deep burn harder
A charred or deep burn has changed the concrete below the surface, and extra scrubbing only roughens the area around it. Stop after a few gentle passes and judge the result once the slab is dry. Pushing harder rarely turns a deep mark into a light one.
Don't sandblast the burn away
Abrasive blasting can strip the surface layer for good, leaving a lighter, uneven patch next to the mark. It can also wear down the edges around the burn. A gentle cleaner tested on a small area will tell you more than blasting ever could.
Don't assume a sealed slab takes the same cleaner
Sealed and stamped concrete can react differently from bare slab, and a cleaner that works on one can dull the other. Test a small, hidden area first and let it dry before you decide. Only move to a stronger product if the gentle one clearly fails.
When to call a professional
A deep burn on a stamped or garage slab is a job for a restoration contractor, since home cleaners can't reach past the surface damage. If you're unsure what made the mark, a testing lab can identify it before anything stronger goes on.
Questions
Can a burn mark on concrete be fully removed?
Light browning often lifts with the gentle steps above, but deep or charred burns usually don't come out completely. The concrete itself has been damaged, so cleaning can only improve the look. For deep marks, the realistic goal is a lighter, less visible mark.
Will scrubbing harder make a burn look better?
No. Harsh tools such as sanding or steel wool can strip the finish and leave a bigger mark. Use the stiff bristle brush with a mild detergent and light pressure, then rinse thoroughly.
When should I try a poultice?
Only when gentle scrubbing leaves a shadow behind once the concrete is dry. Expect it to take several rounds, and check the result after each one. If the mark doesn't change after a few rounds, stop and get it assessed.
Can I use a commercial stain remover instead of a homemade mix?
Yes, a proprietary cleaner made for that exact stain is preferred over a homemade mix. Follow the label closely and test it on a hidden spot first. Keep the stronger cleaner on the stubborn mark rather than the whole slab.
Does a burn mark mean the concrete is ruined?
Not necessarily, but a deep or charred mark usually can't be cleaned away. A professional can tell you whether the damage is only on the surface or goes deeper. Light browning on its own is rarely a sign of lasting damage.
Is a pressure washer safe for a burn on my driveway?
It can be, if you keep it gentle. Stay at 400 psi or lower, use a wide fan tip set between 25 and 50 degrees, and hold it at least 12 inches from the surface. Historic stone should never be power washed, since the pressure can damage it.
Why should I wet concrete before I clean a burn?
Dry concrete drinks up the cleaner along with whatever it has loosened, which can spread the mark and leave residue below the surface. Wetting the slab first keeps the cleaner on top, where the rinse can carry it away. Keep the area damp until you've finished rinsing.
Can I use bleach to lift a burn on concrete?
Bleach suits moss, algae and similar growth, but it isn't a first step for a scorch. Never mix it with ammonia, since that combination makes a toxic gas. If you're unsure what the mark is, test a small area with a mild cleaner before reaching for anything stronger.
