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 that operates 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 same 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. Water cleanup means latex. Mineral-spirits cleanup means oil-based. Read the label if you are not sure.
- 2. Check for PaintCare. If you live in one of the 11 PaintCare states (or DC), skip the rest and use paintcare.org. It is free for both types.
- 3. Latex: dry it out. For small amounts, leave the lid off. For larger amounts, add cat litter or paint-hardener. Trash it once solid.
- 4. Oil-based: do not dry it. Keep the lid on and take it to HHW or PaintCare. Never trash it, never pour it down a drain.
- 5. Find your verified local option. Try /check with your ZIP.
Frequently asked
Can I throw latex paint in the trash?
Yes, once it is 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 it to a household-hazardous-waste (HHW) site, or to 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 the propellant is exhausted), then recycle as metal. A partial can is hazardous waste, so take it to HHW. Never puncture an aerosol can.
Where can I dispose of paint near me for free?
If you live in a PaintCare state (California, Colorado, Connecticut, Maine, Maryland, Minnesota, New York, Oregon, Rhode Island, Vermont, Washington, DC), free paint drop-off is at participating retailers — Hirshfield's, Sherwin-Williams, Home Depot, and 1,800+ other sites. Find the nearest at paintcare.org. In non-PaintCare states, county HHW is the free option.
How much does it cost to dispose of paint?
Free in 12 PaintCare states + at any county HHW facility nationwide. Outside those, some hardware stores accept paint for a $5-15 per-gallon fee, and commercial recyclers charge $25-50 per 5-gallon bucket. Latex paint that you dry yourself and trash is free anywhere.
Is it illegal to pour paint down the drain?
Yes, in all 50 states, under the federal Clean Water Act. Even small amounts of latex paint kill the bacteria in municipal wastewater plants. Oil-based paint contaminates the drinking-water supply. Penalties range from $500 to $25,000+ per violation depending on volume. Always dry, take to HHW, or use PaintCare.
How long does latex paint take to dry?
Small amounts (less than 1 inch deep in the can) with the lid off in a ventilated garage: 24-48 hours. Larger amounts mixed with cat litter or commercial paint-hardener: 2-4 hours. Test by tilting the can — if any liquid moves, it's not done. Trashing wet latex paint can leak in the truck and contaminates loads.
