Mineral Spirits vs. Paint Thinner Difference
Both unblended mineral spirits and blended mineral spirits called paint thinners have an odor similar to camping lantern oil or kerosene. Due to the added benzene, paint thinner will have more of an odor than will pure mineral spirits. The smell is typically sweet and most users do not find it objectionable. Due to the difference in odor, pure mineral spirits tend to be better for interior use.
