To improve accuracy in calculating QCD effects, we propose a method for renormalon subtraction in the context of the operator-product expansion. The method enables subtracting renormalons of various powers in Λ QCD efficiently and simultaneously from single-scale observables. We apply it to different observables and examine consistency with theoretical expectations.
