Paint stains are a common problem in many households. They can be caused by a variety of sources, such as spilled paint, splattered paint, or even just the natural aging of paint. The two crossword solutions for the term 'paint stains' are 'blobs' and 'smears'. Blobs are large, round spots of paint that have been left behind on a surface. Smears are thin, streaky lines of paint that have been smudged or smeared onto a surface. Both blobs and smears can be difficult to remove and can leave behind an unsightly mess.
