Abstract: A scraping tool for removing paint residue from the friction seal of paint cans. The tool includes a handle (10) of sufficient size to accommodate a human hand from which one of two scraping blades continue. Extending from the fore end of the tool is a rim scraping blade (20) while conversely extending from the aft end is a lid scraping blade (30). The blades have contour edges shaped to approximate the cross sectional configuration of the rim and lid components of a paint can friction seal. The seal is cleaned completely, as the tool is designed to address both the rim and lid. Due to slightly smaller or larger blade dimensions, in respect to the seal configuration, the tool is allowed to move without encumbrance over the seal surface as it is cleaned. The blades are shaped to correspond specifically to the surfaces of the friction seal, permitting the tool to be used on assorted sizes of the cans as well as those of various manufacture.
