Getting rid of old paint takes more than simply tossing it in the trash. Whether you’ve got a few cans left over from a project or inherited old supplies, unwanted paint must be handled with care. Many paints contain chemicals that can harm the environment or violate local waste disposal laws if thrown away incorrectly.
This guide covers how to safely dispose of, recycle, or throw away old paint based on the type you have. You’ll also learn what to do with empty cans, how to avoid common mistakes, and where to turn for local recycling or hazardous waste programs.
Identify What Kind of Paint You Have
Before discarding anything, determine what type of paint you’re dealing with. The disposal method depends entirely on this.
| Paint Type | Typical Use | How to Discard It |
|---|---|---|
| Latex (water-based) | Walls, ceilings, general interior use | Dry it out and place in trash (if local rules permit) |
| Oil-based | Trim, doors, furniture, exterior finishes | Must go to a hazardous waste facility |
| Lead-based | Homes built before 1978 | Requires specialized disposal through certified channels |
Look for labels that mention “water cleanup” (latex) or “mineral spirits” (oil-based). If the can is unmarked and the paint is very old, treat it as potentially hazardous.
Safe Disposal Methods for Latex Paint
Latex or acrylic paint is the most common type found in homes. While it’s not classified as hazardous waste, it still must be dried out before you can throw it away.
Here’s how to dispose of latex paint safely:
- Dry it out completely.
For small amounts, leave the lid off and let it dry naturally. For larger quantities, mix in cat litter, shredded newspaper, or a commercial paint hardener until it solidifies. - Place in regular trash with the lid off.
Once hardened, the can may be thrown away with your household garbage. Leaving the lid off lets collectors confirm it’s no longer a liquid.
Always confirm with your city or county’s solid waste department—some areas require all paint waste to be brought to a collection site, even if it’s dry.
How to Discard Oil-Based Paint
Oil-based paints contain flammable solvents and are classified as household hazardous waste (HHW). Improper disposal can result in water pollution, fines, or fire hazards.
To safely get rid of oil-based paint:
- Bring it to a hazardous waste drop-off site.
Most cities and counties provide HHW collection days or permanent drop-off locations. Use Earth911 to find nearby facilities. - Keep it in its original container.
Don’t try to dry it out. Secure the lid, and label the can if the original markings are unreadable.
If your local waste program doesn’t accept paint directly, contact nearby paint or hardware stores—some participate in recycling or take-back programs.
Handling and Disposing of Lead-Based Paint
Lead-based paint is toxic and federally regulated. Homes built before 1978 may still contain it, especially on trim, windows, or siding.
If you suspect you have lead-based paint:
- Do not sand, scrape, or burn it.
Disturbing lead paint creates dangerous dust and fumes. - Hire a certified lead abatement professional for removal.
- Bring unopened or leftover lead-based paint to your hazardous waste facility. Never attempt to throw it in the trash or dry it out yourself.

Recycling or Throwing Away Empty Paint Cans
Empty or nearly empty paint cans may still pose disposal questions. The best method depends on the material of the can and the residue inside.
- Metal paint cans can often be recycled with scrap metal if they’re completely clean and dry.
- Plastic paint cans are rarely accepted in curbside recycling and usually go in the trash—again, only when completely dry.
If there’s even a small amount of liquid paint left, treat the can as if it’s full and follow the appropriate disposal method for latex or oil-based paint.
Take-Back Programs and Paint Recycling Options
Many homeowners aren’t aware that old paint can often be recycled. Paint take-back programs collect unused paint for redistribution, recycling, or safe disposal.
One of the largest programs in the U.S. is PaintCare, available in select states. These programs accept:
- Interior and exterior latex paint
- Oil-based paint and stains
- Primers and sealers
- Varnishes and clear finishes
You can usually drop off paint at participating hardware stores, including Sherwin-Williams, Ace Hardware, and select Lowe’s locations. Always call ahead to verify accepted materials and volume limits.
Common Paint Disposal Mistakes to Avoid
When it comes to getting rid of old paint, the biggest risks come from doing it the wrong way. Here are a few practices to avoid:
- Never pour paint down the drain or into storm sewers.
This can contaminate waterways and is illegal in many areas. - Don’t mix different types of paint together.
It may produce chemical reactions or complicate disposal. - Don’t try to burn or bury paint.
Paint fumes can be toxic, and buried containers may leak over time. - Avoid throwing away liquid paint.
Let it dry or take it to the proper disposal site.
Proper disposal isn’t just about avoiding penalties—it protects drinking water, wildlife, and community health.
Final Thoughts on Getting Rid of Old Paint
Getting rid of old or unwanted paint doesn’t have to be difficult, but it does require attention to safety, legality, and environmental impact. The most important step is knowing what kind of paint you’re working with—because that determines everything else.
From there, you can choose the right method to discard, recycle, or drop it off. If you’re ever unsure, reach out to your local waste management agency or use tools like Earth911 or PaintCare for help finding nearby solutions.
