Yes, paint thinner is commonly used to remove paint, especially when it comes to cleaning brushes, rollers, and other painting tools. It can also be used to thin oil-based paints and varnishes for easier application. However, the effectiveness of paint thinner for paint removal depends on factors such as the type of paint being removed and the surface it's applied to. Additionally, proper safety precautions should be taken when using paint thinner, as it can be flammable and produce strong fumes.
