Quick Answer
Okay, so here's the quick version. If the oil spill is fresh, I mean still wet, don't just stare at it! Throw some clay kitty litter, sawdust, or even cornstarch on it right now. Let it soak up the mess for a day, then sweep it up. For older, uglier stains that have been there a while, you're gonna need a real degreaser and some elbow grease. Something like Oil Eater or a poultice cleaner. You can try this yourself for maybe $20-50 in materials. If it's a huge disaster, it might be worth calling a pro to save the headache.
Common Symptoms
Possible Causes
Step-by-Step Diagnosis
Step 1
Identify the age of the stain - is it a fresh spill or an old, set-in stain?
Step 2
Determine if the concrete is sealed or unsealed by pouring a little water on it. If it soaks in, it's unsealed.
Step 3
Check the current temperature. Adegreasers and cleaners work best in temperatures above 50°F (10°C).
Step 4
Assess the size of the spill to determine how much product you'll need.
Step 5
Test your chosen cleaning method on a small, hidden area first to avoid discoloration or damage.

When to Call a Professional Concrete
- When your DIY attempts with degreasers and scrubbing haven't worked.
- If the stained area is very large, like an entire driveway.
- If you're preparing to sell your home and need the best possible curb appeal.
- When you lack the proper equipment, like a hot water pressure washer, to tackle the job effectively.
Prevention Tips
- Place a large piece of cardboard or a dedicated drip pan under leaky vehicles.
- Address and repair vehicle fluid leaks as soon as you notice them.
- Clean up any spills immediately with an absorbent material like clay kitty litter.
- Consider sealing your driveway and/or garage floor with a quality concrete sealer.
