Leftover acrylic thinners should never be poured down the drain
dumped on the ground
or thrown in the regular trash.
This substance is highly combustible and poses serious risks to ecosystems and human well-being.
The safest way to dispose of them is through a local hazardous waste collection program
Numerous municipalities provide fixed disposal sites or periodic pickup events for toxic home substances.
Reach out to your county’s waste control office to confirm drop-off schedules and approved locations for thinners.
If your remaining quantity is negligible
you may allow it to air out in a ventilated space free from sparks or open flames
Pour the thinner into a shallow metal or glass container
and leave it uncovered in a secure outdoor space, such as a garage or patio
where children and pets cannot reach it.
Once the liquid has fully evaporated and only dry residue remains
you can dispose of the container in your regular trash.
Protect your skin with protective gloves and ensure ample airflow during use.
Never mix acrylic thinners with other chemicals like paint strippers or solvents
since unpredictable and hazardous chemical reactions may occur.

Responsible disposal protects your community and the environment.
