Short answer: Clean tools right after the last coat: wash latex tools with warm water and soap, use mineral spirits only for oil-based paint, and follow local rules for paint disposal.

Clean-up is where paint jobs go wrong: a brush left overnight can be ruined. The method depends on the paint. Water-based (latex) paints wash out with warm water and soap; oil-based paints need mineral spirits or a specialty cleaner. Always read the can.

Do not pour paint or solvents down drains or onto the ground. Local rules vary, so check your municipality's guidance for leftover paint, thinners and rags. Used rags with oil-based products can be a fire hazard, so follow the manufacturer's disposal instructions.

Cleaning brushes and rollers

Who it is for: anyone using water-based paints.

Remove excess paint first, then wash under running water until it runs clear. A comb and spinner make the job faster.

Oil-based and stubborn paint

Who it is for: people who used oil-based paint or let latex dry on a tool.

Use mineral spirits in a ventilated area and follow the label. Wear gloves and eye protection.

Wiping spills and splatters

Who it is for: anyone who finds drips on floors, trim or hardware after painting.

Wipe wet paint quickly. Test cleaners on a hidden spot because some strip finishes.

Storing and labeling leftovers

Who it is for: anyone keeping paint for touch-ups.

Seal the can tightly and label it with color, sheen, date and room.

FAQ

Can I wash latex paint brushes in the sink?
Many people do with warm water and soap, but avoid rinsing large amounts of paint down household drains. Wipe off excess first and check your local rules.
How do I clean a roller cover?
Scrape off excess paint, wash with warm soapy water until clear, spin or squeeze dry and stand it on end to air dry. Disposable covers can be thrown away.
How long does leftover paint last?
An unopened can can last years in a stable environment, and a properly sealed opened can often lasts a year or more. Check for smell, lumps and separation before using.
How do I dispose of leftover paint?
Check your local household hazardous waste program. Many places accept liquid paint, and some allow dried latex paint in regular trash.
