Let R be a commutative ring with identity. R is called clean (respectively, almost clean) if every element in R is a sum of an idempotent and a unit (respectively, a regular element). In this paper, we clarify conditions under which the two overrings RðxÞ and Rhxi of the ring of polynomials R½x are (almost) clean rings.
