A solar panel cleaning system includes a brush connected by a hose to a fluid supply. The brush has scrubbing material, such as bristles, attached to a brush body for mechanically cleaning the surface of the solar panel. The width of the contact surface of the scrubbing material may be equal to the width of the solar panel, so that the solar panel may be cleaned with only upward and downward strokes. The brush body may further support a fluid manifold that receives the fluid from the fluid supply. The fluid manifold may include nozzles that emit the fluid under pressure onto the solar panel. The nozzles may project both frontward and rearward of the brush body so that the fluid sprays off the solar panel in front of and behind the brush. Spray patterns of the nozzles may overlap and impinge the entire width of the solar panel.

A method of forming a bristle field for an oral care implement. The method includes providing a bundle of bristles and aligning the bundle of bristles with an insertion opening in a guide member. Upon insertion into the guide member, the guide member divides the bundle of bristles into a plurality of bristle tufts. The guide member can be aligned with tuft holes on a head or head plate of an oral care implement so that the bundle of bristles can be inserted through the guide member and into the tuft holes. As a result, a single bundle of bristles can be used to mount a plurality of bristle tufts to the head or head plate.

A paint brush includes a handle including a base generally defining a solid cylinder, the base further including a proximal region, the handle having an axial hollow channel, the channel having a spiral threaded interior beginning at a proximal end of the channel and ending at a distal end of the handle, the spiral threading proportioned for engagement of a threaded paint pole extension. Beginning at a distal end of the base is a paint brush neck having an integral hollow segment of a flexible accordion-like corrugated material, and the axial channel extending into the neck without threading on it. Disposed distally of the corrugated material and integral with it is an integral bristle support region having a bristle securing recess proportioned for securement of bases of paint brush bristles, the recess including an upper and a lower region, the lower region proportioned for selectable receipt of paint bristles, the bristle-securing recess including an upper and a lower region, the upper region defining mutually slanted planes each in a range of about 20 to about 40 degrees relative to the axial channel, the upper and lower regions defining a funnel for directing excess or splashed paint toward the bristle securing recess.

A paint brush and method include a ferrule extending around and in contact with a plurality of bristles and a spacer apparatus positioned to space apart the plurality of bristles to provide at least one reservoir within the plurality of bristles. The spacer apparatus defines at least one opening extending through the spacer apparatus that allows fluid passage therethrough to the at least one reservoir to assist in removal of paint from the plurality of bristles when fluid is provided therein.

A frayed cable scaling tool is made by fraying the end of a cable so that it forms a wire brush. A collar or other way of keeping the cable from unraveling too much is necessary. When powered by a pneumatic saw power tool, the scaling tool is very effective at removing scale, rust, carbon, or other debris. The flexibility of the cable allows the frayed end of the cable to move vigorously in a random motion, which is effective for scrubbing. For some applications, it is preferred to enclose the cable and/or the collar in a guide tube.

A brush bar including a central core in the form of a rigid tube, a plurality of outwardly extending bristles in the form of at least one bristle strip, and a sealing material extending over substantially the entire remaining circumferential and axial extent of the brush bar, the at least one bristle strip having a root portion which is sandwiched between the sealing material and the central core or which is attached on top of the sealing material.
