Basement Clean-Out? Here’s How to Handle Old Paint the Right Way
If you’re like most homeowners, you probably have a few half-used paint cans sitting in the basement, garage, or utility room.
The question is… what are you supposed to do with them?
Tossing liquid paint straight into the trash (or worse, pouring it down a drain) isn’t safe for your home or the environment. The good news is that disposing of old paint properly is simple once you know the steps.
Step 1: Determine If It’s Latex or Oil-Based
Most modern interior paint is latex (water-based), but older paint may be oil-based.
Latex paint can often be dried out and disposed of with regular trash.
Oil-based paint usually needs to be taken to a household hazardous waste facility.
If you’re unsure, check the label on the can.
Step 2: For Latex Paint — Let It Dry Completely
Latex paint must be completely solid before disposal.
You can:
Leave the lid off and let it air dry (small amounts)
Add cat litter, sawdust, or a commercial paint hardener to speed up the process
Once it’s fully hardened, you can dispose of it in your regular trash (with the lid off in many municipalities — check local guidelines).
Step 3: For Oil-Based Paint — Use a Hazardous Waste Drop-Off
Oil-based paints, stains, and solvents should be taken to a local household hazardous waste site. These facilities are equipped to dispose of materials safely.
A quick search for “household hazardous waste near me” will point you in the right direction.
A Quick Homeowner Tip
Before you dispose of a can, make sure you truly won’t need it again. Keeping a small, well-labeled container of leftover paint for touch-ups can save you time and money later.
