Abstract: A cleaning apparatus for the on-site de-scaling of a stationary object, includes a housing having a plurality of panels detachably mounted to the housing side wall exterior surface so that the panel outer faces are radially oriented in relation to the housing. A plurality of elongated cleaning members, such as bristles or needles, each includes a first end mounted to one of the panels and a second end extending away from the panel outer face. The elongated cleaning members extend radially outwardly from the housing and the elongated cleaning members are adapted to contact a surface of the stationary object to be cleaned and de-scaled.

Abstract: An apparatus for clearing around an associated stationary object includes a housing having a top wall, a side wall, and at least one opening extending through the side wall. At least one paddle member is mounted to and extends radially outward from an exterior surface of the housing. The paddle member is adapted to clear around the associated stationary object. The apparatus further includes a plurality of elongated cables mounted to a support that is selectively secured to an interior surface of the housing. The elongated cables are adapted to clean around the associated stationary object.
