A cleaning device for cleaning an orifice in a condensate removal device that is capable of use while the condensate removal device is on-line, i.e. during operation. In one aspect, the cleaning device provides a reciprocally movable cleaning rod that can be retractably insertable into the orifice. This can be done without affecting the sealed volume defined around the orifice. In another aspect, the cleaning device includes a retractable hood or shield over the cleaning rod, to protect when not inserted in the orifice.
