# How to dispose of paint (latex and oil-based)

Paint is one of the most searched household disposal problems in the U.S. The answer depends on chemistry: **latex (water-based)** and **oil-based** are not the same stream. Getting that wrong is how people get rejected at the gate or create a hazardous load in a trash truck.

Step 1: Read the can

• **Latex / acrylic / water-based** — often solidifiable or PaintCare/HHW
• **Oil-based / alkyd / stain / solvent** — almost always household hazardous waste (HHW)
• **Aerosol spray paint** — usually HHW; do not puncture

If the label is gone, treat unknown liquid paint as HHW.

Latex paint: what usually works

Many cities allow **fully dried** latex to be trashed as a solid. That means:

• Absorb leftover liquid with cat litter, sawdust, or a commercial hardener
• Leave the lid off only if your city instructs that method
• Put dried cans in the trash if local rules allow — empty metal cans sometimes recycle when bone-dry and accepted

Never pour latex down a drain or storm sewer. “Water-based” does not mean sewer-safe in volume.

Some states participate in **PaintCare** or similar producer programs — drop-off at paint retailers. That is often easier than county HHW for latex and many oil products. Confirm your site accepts the product type before you drive.

See latex paint.

Oil-based paint: HHW only

Oil-based paint, spar varnish, and many primers are flammable HHW. Do not dry them in the open as a DIY trash hack if your city requires HHW intake. Transport upright, sealed, and labeled. See oil-based paint.

Partial cans and “leave it for the next owner”

Leaving usable paint for a neighbor is fine if you arrange pickup. Abandoning open cans in an alley is dumping. For move-outs, budget an HHW trip the same week you handle batteries and bulbs.

What not to do

• Mix oil and latex in one jug “to finish it”
• Hide liquid paint in a black trash bag
• Toss aerosol cans in recycling full of product
• Burn paint cans
• Assume every hardware store is a PaintCare site

How to use DumpRegistry

• Start at latex paint or oil-based paint
• City HHW guides: Chicago oil-based paint, New York, San Diego latex, Phoenix
• Filter Centers when you need a drop-off map

If your city page says dry-out is allowed, follow that source’s steps exactly — drying rules are local, not universal.
