How to dispose of paint
The right answer depends on whether your paint is latex (water-based) or oil-based / solvent. Latex is usually trash-safe once dried; oil-based is hazardous waste and must be taken to a household-hazardous-waste (HHW) site. If you live in one of the 11 PaintCare states, both can be dropped at a participating retailer for free.

Latex (water-based) paint
Latex paint is the most common type sold today (water cleanup, low odor). It's not hazardous once dried. Federal EPA RCRA rules let dried latex paint go in regular trash; about 40 states explicitly confirm this in their guidance.
To dry small amounts (< 1 inch in the can): leave the lid off in a well-ventilated area until solid. For larger amounts, mix in cat litter, sawdust, or a commercial paint-hardener (sold at any hardware store). Once solid, place the can (lid off) in regular trash. The empty can is recyclable as scrap metal.
Oil-based / solvent / alkyd paint
Oil-based paints, stains, varnishes, and shellacs are federally regulated as hazardous waste (RCRA D001 ignitable). Never trash, never pour down a drain, never put in curbside recycling. Take to your county HHW site (free for residents) or a PaintCare participating retailer if you're in a PaintCare state.
Aerosol spray paint
An aerosol can with paint or propellant still inside is hazardous (pressurized + flammable). Use it up completely (spray onto cardboard until no more comes out), then recycle the empty can with scrap metal. If the can won't empty — never puncture it — take it to HHW.
PaintCare states (free retailer drop-off)
PaintCare is the industry-funded paint stewardship program operating in California, Colorado, Connecticut, Maine, Maryland, Minnesota, New York, Oregon, Rhode Island, Vermont, and Washington (plus DC). It runs free drop-off at over 2,000 retailers — typically the paint stores that sold it. Find the nearest site at paintcare.org/find-a-drop-off-site.
Step-by-step: prep + drop off
- 1. Identify the type. Cleanup with water = latex. Cleanup with mineral spirits = oil-based. Read the label if unsure.
- 2. Check for PaintCare. Live in one of the 11 PaintCare states + DC? Skip everything else and use paintcare.org. Free for both types.
- 3. Latex: dry it out. Small amounts: lid off. Larger: add cat litter or paint-hardener. Trash once solid.
- 4. Oil-based: don't dry it. Keep the lid on and take to HHW or PaintCare. Never trash, never down a drain.
- 5. Find your verified local option. Use ClearPath /check with your ZIP.
Frequently asked
Can I throw latex paint in the trash?
Yes, once it's fully dried (no liquid left). Most counties allow dried latex paint in regular trash; some require the lid be off so trash inspectors can see the can is solid. Never trash liquid paint — even latex.
Is oil-based paint hazardous waste?
Yes. Federal EPA rules classify it as RCRA D001 ignitable hazardous waste. Take to a household-hazardous-waste (HHW) site or a PaintCare retailer in PaintCare states. Free for residents.
What is PaintCare and where does it work?
PaintCare is the industry-funded paint stewardship program that runs free drop-off in California, Colorado, Connecticut, Maine, Maryland, Minnesota, New York, Oregon, Rhode Island, Vermont, Washington, and DC. Find the nearest site at paintcare.org.
How do I dry latex paint quickly?
Mix in cat litter, sawdust, or a commercial paint-hardener (sold at hardware stores). For small amounts (under an inch), leaving the lid off in a well-ventilated area works in 24-48 hours.
Can I recycle the empty paint can?
Yes — once fully empty and dry, a paint can is scrap metal. Check your county's curbside-recycling guide; some accept metal cans curbside, others require drop-off at a scrap-metal facility.
What about spray paint cans?
Use them up completely (spray onto cardboard until propellant is exhausted), then recycle as metal. A partial can is hazardous waste — take to HHW. Never puncture an aerosol can.
