Does paint thinner leave a residue?

Yes, paint thinner can leave a residue depending on the type and brand used. Some paint thinners contain additives that may not evaporate completely, resulting in a greasy or sticky film on surfaces. Additionally, if not properly wiped away, any leftover paint thinner can attract dust and dirt, further contributing to residue buildup. To avoid this, it's essential to thoroughly clean surfaces after using paint thinner.
