How to Get Rid of Paint Responsibly
Getting rid of paint isn’t as simple as tossing a can in the trash. Improper disposal can harm sanitation workers, contaminate the environment, and lead to local fines. Whether you’re dealing with leftover latex paint or unused oil-based paint, this guide explains how to dispose of paint safely and responsibly.
Quick Answer
How you dispose of paint depends on the type.
Latex or water-based paint: Dry it out, then throw it away.
Oil-based paint: Take it to a hazardous waste facility.
Usable paint: Reuse, donate, or recycle when possible.
When to Get Rid of Old Paint
Paint can last for years when properly stored, but like everything, it can't last forever. So how can you tell when to get rid of it? Here are some key ways to identify when old paint has gone bad:
1. Unusual consistency–lumps, rough texture, or dried chunks typically mean the paint has gone bad.
2. Bad smells–a sour, rancid, or foul odor is a tell-tale sign your paint has reached its expiration.
3. Mold–water-based or latex paint can grow mold if it's old or improperly stored.
Does Paint Have an Expiration Date?
Paint doesn’t have a specific expiration date, but all paint will eventually go bad. The shelf life of paint varies depending on the type and how well it was stored. Properly stored latex or water-based paint will last up to 10 years, and oil-based paints can last up to 15.
Can You Throw Away Paint?
Before you toss, first check to see what type of paint you have, and then follow the following guidelines for your type of paint.
Oil-based paints, also known as alkyd paint, can never be thrown into a garbage bin or dumpster. You will have to take it to a household hazardous waste facility to be properly processed. Latex or water-based paints can be thrown out in the garbage with your other waste, but must first go through a drying process before you can toss them. .
How to Dispose of Latex or Water-Based Paints
Liquid paint should not be thrown away because it can contaminate groundwater. Instead, it should be dried and hardened before being thrown out with your regular trash and recycling.
Never throw away liquid paint. It must be dried first.
If the can is nearly empty:
Remove the lid
Let the paint dry completely (sunlight speeds this up)
If there’s a lot of paint left, you have a few options:
Mix in paint hardener
Add cat litter, sand, or another absorbent material
Pour paint into a lined box and allow it to dry
Always confirm disposal rules with your local sanitation provider.
How to Dispose of Oil-Based Paint
Unlike latex paints, oil-based paints are considered hazardous because they are flammable and contain toxic metals. To properly dispose of oil-based paint, it must be taken to a facility that accepts hazardous waste. Some tips for oil-based paint disposal:
1. Locate the nearest hazardous waste facility near you and make sure paint is accepted at that facility.
2. Look into Household Hazardous Waste collection events near you to bring your paint to.
3. In some states like Colorado, Connecticut, Vermont, and California, paintcare.org has take-back programs to recycle unused paint.
Make sure to also never let oil paint evaporate, as this can cause air pollution and affect wildlife and the environment.
How to Dispose of Acrylic Paint
Acrylic paint is a chemical-based paint, but you can treat it like latex paint by letting it harden before you dispose of it with your other trash.
How to Dispose of Empty Paint Cans
If paint cans are completely empty and dry, they can be disposed of in your household trash. Leave the lid off and place the empty cans with your recycling for curbside pickup.
What Not to Do
Don’t dump paint on the ground
Don’t flush paint down drains or toilets
Don’t pour liquid paint into trash bins or dumpsters
Don’t allow oil-based paint to evaporate
How to Properly Store Paint
If you properly store paint, it can last for years, and you don't have to worry about disposal as often. Keep paint in a dry, dark place. The optimal temperature for storing paint is 60 to 80°F (15 to 27°C). Air circulation also ruins paint, so wipe the rim before sealing the lid tightly.
Tips for Eco-Friendly Paint Disposal
Eco-friendly paint disposal helps save the environment. Use these tips for responsible paint disposal:
Choose latex paint instead of oil-based paint.
Plan how much paint you need before buying.
Store leftover paint properly or use it up.
See if your paint retailer has a take-back program.
Donate paint in good condition to local community centers, shelters, or organizations like Habitat for Humanity and Global Paint for Charity.
How to Discard Paint Where You Live
Paint disposal rules vary by city and state, so it’s always best to check local guidance before getting rid of old paint. Your municipality may offer specific programs or requirements depending on the type of paint you have.
To find the right option in your area:
Contact your local waste or sanitation department to confirm whether dried latex paint can go in the trash and where oil-based paint should be taken.
Check for household hazardous waste collection events, which often accept oil-based paints and other materials that can’t go in regular garbage.
Look for PaintCare or retailer take-back programs, available in some states, that allow you to return unused or leftover paint for proper recycling.
Taking a few minutes to check local options helps ensure paint is disposed of safely, legally, and responsibly.
