Safely Dispose of Old Paint Cans: A Step-by-Step Guide

Updated: Feb 15

If you're like many homeowners or DIY enthusiasts, you probably have some old paint cans lying around, taking up space and posing a potential environmental hazard. Disposing of old paint cans properly is not only essential for the environment but also ensures you comply with local regulations. In this guide, we'll walk you through the steps to safely and responsibly dispose of old paint cans.

Step 1: Check the Contents

Before you can safely dispose of old paint cans, it's important to determine the condition of the paint inside. If the paint is still in good condition and you anticipate using it in the future, consider storing it properly. Ensure the lids are sealed tightly and store the paint in a cool, dry place away from direct sunlight. If the paint has dried or is no longer usable, you can proceed with disposal.

Step 2: Choose the Right Disposal Option

There are a few options for disposing of old paint cans, and the best choice may depend on your local regulations and the type of paint you have:

Local Household Hazardous Waste Collection: Many municipalities offer special collections for hazardous waste, including old paint. Contact your local waste management agency to find out about scheduled collection events or permanent disposal facilities in your area. This is typically the safest and most eco-friendly option.

Latex Paint Disposal: If you have latex-based paint (water-based), it is less hazardous than oil-based paint. In some areas, it may be acceptable to solidify latex paint by mixing it with an absorbent material such as cat litter or sand. Once it's solidified, you can dispose of it with regular household trash. Be sure to check local regulations to confirm this option.

Oil-Based Paint Disposal: Oil-based paint is considered hazardous waste in most locations. Take it to a household hazardous waste collection center, where it can be disposed of safely and in accordance with environmental regulations.

Step 3: Prepare the Paint Cans

Before disposing of the paint cans, you'll need to prepare them:

Allow Latex Paint to Dry: If you're solidifying latex paint, leave the lid off the can and let it air dry. Once it's solid, it can be safely disposed of.

Oil-Based Paint Cans: For oil-based paint, it's important to keep the cans sealed. Ensure the lids are tightly secured to prevent leaks during transport. You can also place the cans in a plastic bag or container to further contain any potential spills.

Step 4: Transport Safely

When transporting old paint cans, place them in a sturdy box or container to prevent tipping or leaks. Make sure the lids are tightly sealed to avoid any spills or accidents during transport.

Step 5: Follow Local Regulations

Before disposing of old paint cans, be sure to adhere to your local regulations. Different regions may have specific guidelines for hazardous waste disposal, so it's essential to follow their recommendations to avoid fines or penalties.


Properly disposing of old paint cans is not only good for the environment but also ensures you comply with local laws and regulations. By following the steps outlined in this guide, you can safely and responsibly dispose of old paint cans, minimizing the impact on the environment and your community. Remember to always check with your local waste management agency for specific guidelines and collection events in your area.
