To get rid of thinner solvents, you need to follow safe disposal steps. Thinner solvents are chemicals used to thin paints and clean tools.  To dispose of them, check local rules first. Small amounts can be mixed with materials like cat litter until they become solid, then put in the trash. Larger amounts might need special disposal places. Never pour them down drains or on the ground, as this can harm the environment. It is important to remember to keep people, animals, and nature safe when getting rid of these chemicals.
