Solvent-based cleaners are cleaning products that use solvents as their primary ingredient to dissolve dirt, grease, and stains. These solvents can be derived from petroleum or other organic sources and are effective in breaking down tough residues on various surfaces, including metals, plastics, and fabrics. Common examples of solvent-based cleaners include paint thinners, degreasers, and adhesive removers. While solvent-based cleaners are powerful, they can also emit strong fumes and may require proper ventilation during use. It's important to follow safety guidelines, such as wearing gloves and masks, to minimize exposure. Additionally, some solvents can be harmful to the environment, so proper disposal is essential.
