- Wipe with washing soda or detergent in water, then rinse clean.
Candle wax on concrete is a stubborn job once it's been left to set, because the slab is porous and soaks up whatever you put on it. Fresh wax lifts in a few passes, while wax that has sat a long time can leave a tint that needs more rounds, especially from colored candles. A water repellent or sealer on the slab can block the cleaner, so look for one before you start.
Test any cleaner on a small, hidden patch of the slab first, since porous concrete soaks up what you apply. If you're trying to get wax off concrete that's been polished, keep pressure light so the shine stays intact. A candle wax stain on concrete that still shows after that is a job for a pro.

5 steps
Step by step
Step 1 of 5
Harden the wax with ice
Put an ice cube in a plastic bag and hold it against the wax. Keep it there until the wax firms up.
Step 2 of 5
Scrape off the loose wax
Use a dull knife, spoon, spatula or the edge of a plastic credit card to lift the wax residue off the surface. Work gently and keep the tool low and flat, so you lift the wax rather than pushing it into the concrete.
Step 3 of 5
Wipe with washing soda or detergent
Dip a sponge or soft cloth in a solution of washing soda or detergent and water. Wipe over the spot until the last of the wax film comes away.
Step 4 of 5
Rinse with clear water
Rinse the spot well with a sponge or cloth dipped in clear water. Keep rinsing until no cleaning solution is left on the concrete.
Step 5 of 5
Dry the spot and check it
Wipe the area dry with a soft clean cloth. Look at it in good light once it has dried before you decide the job is finished.

Best products for candle wax on concrete, brick & driveways
Washing soda and plain detergent are the product types to look for, and you only need one of them for the wipe. Buy a stain product made for wax on concrete only if the stubborn-stain treatment above doesn't clear the spot.
Amazon Basics Microfiber Cleaning Cloths
How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on concrete, brick & driveways, and its directions fit the steps above.
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
Each round should leave less wax on the cloth and a less glossy patch on the slab. Wait until the spot is fully dry before you judge it, since damp concrete hides how much is left. If the wax stays glossy and won't lift even after a gentle scrape, it has set into the pores, so move to the older-stain approach.
What changes for yours
Adjust for your concrete, brick & driveways
Concrete
Concrete is the surface these steps are written for, so the method applies as it is. The wax sits on top, so most of the work happens in the scraping, and the washing soda wipe only has to clear the thin film left behind.
Check the spot once it has dried, since that's when you can judge it best. If the wax is gone but the spot still looks off, the stubborn-stain treatment above is the next step.
Melted on concrete
Melted wax that has spread across the concrete needs a longer chill before you touch it. Let the ice work until the whole puddle is firm, then scrape in small passes.
Once the top layer is off, the washing soda wipe and rinse handle what's left. Working in small passes keeps the scraped wax from smearing across the slab.
Old, dried or set-in stains
Older wax that has built up needs stronger methods, and each one carries more risk of damage to the concrete. Start again with the ice and gentle scraping, then wipe with the washing soda or detergent solution before going further.
When a stain has dried into the concrete and the wipe doesn't lift it, a poultice is the next step. Mix talc, whiting, fuller's earth, diatomaceous earth or clay with the right solvent for the stain to a paste, and spread it at least 1/8 inch thick over the spot. Cover it with plastic and leave it for 24 hours, then let it dry before scraping or brushing it off.
If the mark is still there after a poultice, repeat the poultice rather than switching to harsher cleaners. Proprietary stain-specific cleaners are the better choice over homemade mixes, so buy one made for the stain before you try another mix.
Vinegar, baking soda, peroxide and more
Do home remedies work on candle wax on concrete, brick & driveways?
Most of the home remedies people reach for don't belong on this job, so the steps above are the ones to follow. Polished concrete has a sealer or finish that a cleaner can damage, so removing wax from it carries some risk. Test any cleaner in a hidden corner first, and stop if the finish looks dull or changes.

What makes it worse
Mistakes to avoid
Don't use soap
Skip soap in the wipe and the mix; washing soda or detergent in water is what this job calls for. Washing soda or detergent mixed in water is the right wipe for this job.
Don't scrape with a sharp blade
A sharp blade can cut into the concrete and leave a mark that looks worse than the wax. Use a dull knife, spoon, spatula or the edge of a plastic credit card instead.
Don't heat the wax to lift it
Heat only melts the wax again and spreads it across the slab. The ice and gentle scraping remove it without spreading it.
Don't skip the clear-water rinse
A film left by washing soda or detergent can make the spot look hazy and tempt you into more scrubbing. Rinse with a sponge dipped in clear water until the surface feels clean, then wipe it dry with a soft cloth.
Don't mix bleach with ammonia
Bleach and ammonia together release a toxic gas, so never use one right after the other without a full rinse. Rinse the spot with plain water between any two products, even if you're only trying a second option.
When to call a professional
If the mark stays after a few careful rounds, the wax has likely soaked deep, and a restoration contractor can test a small patch before anything stronger goes on. Tell them it's candle wax, whether the concrete is polished, and which cleaners you've already tried.
Questions
Why does the spot still look different after the wax is gone?
That's usually the dye, not the wax, because colored candles can leave a tint behind once the wax is removed. Check the spot in good light after it dries, and if the tint stays, use the stubborn-stain treatment above.
Do I need to rinse if the spot looks clean?
Yes. A cleaning solution left on the concrete can leave its own film, so rinse with clear water even when the wax looks gone.
What if the wax has been sitting there for a long time?
Older wax needs more work, so start with the stubborn-stain treatment above rather than working harder on the surface. Keep the method gentle, because stronger methods carry more risk of damage to the concrete.
Is it safe to use a stronger cleaner to speed things up?
No. Strong cleaners carry a risk on this surface, and the washing soda or detergent wipe is the safe choice. If it doesn't clear the spot, use the stubborn-stain treatment rather than a harsher product.
Can I pressure wash the wax off my concrete?
Not as a first step. Pressure can push softened wax into the pores and etch the surface, so lift and wash the wax first. If you rinse with a hose afterward, keep the pressure low and the water warm.
Why should I wet the concrete before I clean it?
A damp surface keeps the washing soda solution from sinking into the concrete, where it can't be rinsed out. Dampen the area before you start and keep it wet through the wipe-down. It's a small step that keeps the cleaner working on the surface where you can reach it.
Can I use bleach to lift the tint from colored wax?
Bleach isn't the right tool for a candle dye tint. It's listed for moss, algae and similar growth, and it should never be mixed with ammonia, because that combination gives off a toxic gas. For a leftover tint, repeat the washing soda wipe and rinse thoroughly before you judge the spot.
