DETAILED DESCRIPTION OF THE INVENTION
 Embodiments of the present invention provide a system and method for efficiently removing dust and debris from delicate music instruments and electronic displays. The following description is presented to enable one of ordinary skill in the art to make and use the invention and is provided in the context of a patent application and its requirements.
 Various modifications to the preferred embodiment and the generic principles and features described herein will be readily apparent to those skilled in the art. Thus, the present invention is not intended to be limited to the embodiment shown but is to be accorded the widest scope consistent with the principles and features described herein.
 FIG. 1-FIG. 5 illustrate a cleaning brush 100 according to a preferred embodiment of the present invention, wherein: FIG. 1 illustrates a perspective view of cleaning brush 100, FIG. 2 illustrates a top view of cleaning brush 100, FIG. 3 illustrates a right-hand side view of cleaning brush 100, the left-hand side being a minor image, FIG. 4 illustrates a front view of cleaning brush 100, and FIG. 5 illustrates a rear view of cleaning brush 100.
 Cleaning brush 100 is a multimodal contact cleaner having both a first head 105 and a second head 110 coupled by an offset handle assembly 115. First head 105 includes a thin flat planar profile wrapped or otherwise covered in or supporting a cleaning surface. Some embodiments of the present include a cleaning surface specifically adapted to reach between a set of music strings and a soundboard, or for removing fine particulate matter from a face of an electronic display, or other surfaces. First head 105 includes a generally polygonal profile having a pair of opposing cleaning planes 117 and a plurality of cleaning sidewalls 119 (planes and sidewalls collectively cleaning faces). For a quadrilateral (e.g., rectangular) polygonal first head 105, the profile includes a pair of opposing sidewalls 1191 and an intermediate forward sidewall 1192. Other profiles of first head 105 may be implemented besides the specific illustrated profile. Other polygonal profiles (regular or irregular) include triangles, other quadrilaterals (square, rhombus, trapezoid, kite, and the like), pentagons, hexagons, and the like. A forward portion of first head 105 may be tapered (e.g., having a width at the forward portion that is different (e.g., narrower) that a width at a rearward portion and/or having a thickness at the forward portion that is different (e.g., narrower) that a thickness at a rearward portion. Cleaning brush 100 is illustrated as having a uniform width and thickness for first head 105.
 The cleaning surface is distributed on one or more cleaning faces depending upon implementation. In some implementations, the cleaning surface is wrapped around, adhered to, or otherwise secured to first head 105 to cover both cleaning planes 117 and cleaning sidewalls 1191. Other embodiments provide the cleaning surface on other combinations of cleaning planes and cleaning sidewalls. For example, the cleaning surface is sometimes provided on a single cleaning plane 117, with or without the cleaning surface extending to one of sidewalls 119. In other embodiments, the cleaning surface is provided on both cleaning planes and may exclude the cleaning surface from one or more of sidewalls 119. Some embodiments have the cleaning surface cover an entire cleaning face and other embodiments include one or more partially covered cleaning faces.
 The cleaning surface in FIG. 1 includes microfiber surfaces. As used herein, microfiber is defined as a synthetic fiber measuring less than one denier and with less than 1.5 Decitex per filament (Decitex being a measure of linear density--ten thousand meters of a 1-decitex fiber weighs one gram). These microfibers may be combined to create yarns which are knitted or woven in a variety of constructions. These microfibers are made of polyester, polyamide or other polymers, including polymers of polypropylene, and combinations thereof, and may be constructed from split conjugated fibers of polyester and polyamide (e.g., 100% polyester microfibers). Depending upon the particular application and intended use, the microfiber is chosen for a particular characteristic including softness, durability, absorption, wicking ability, water repellency, among other characteristics. In some implementations, first head 105 may include other material design for fine precision contact cleaning in narrow confined spaces.
 The cleaning surface may not be 100% microfiber. In some embodiments, the cleaning surface varies between 0-100% microfiber, most preferably using microfibers particularly configured for cleaning applications. The cleaning surface may include other combinations of woven and non-woven non-microfiber cleaning material.
 Particularly for instruments such as a guitar, banjo, fiddle, violin, viola, and the like, first head 105 may be made thin and flexible with the cleaning surface disposed on both cleaning planes 117. Electronic displays may be incorporated or associated with computers, tablet computers, and other electronic devices, which includes both portable and non-portable electronic devices. For such electronic displays, first head 105 may be made thin and flexible with the cleaning surface disposed on a single cleaning plane 117. As noted above, the flat planar profile need not be rectilinear; the profile may include triangular or other multisided arrangements particularly adapted and optimized for specific implementations and design considerations. In some implementations, first head 105 will not be flat, but may be rounded or have some other appropriate cross-section. First head 105 may be detachable, such as use of a quick-connect coupler, for cleaning or exchange, or it may include a replaceable microfiber cleaning pad that is wrapped around a template and retained in place.
 Bristle head 110 includes a set of bristles, brush fibers, and the like designed for more coarse removal requirements, such as dusting and detailing other parts of a music instrument or electronic device, such as keys, housings, cases, and the like. Bristle head 110 may be detachable/replaceable as well. Bristle, as used herein, encompasses stiff hair, feather, or synthetic polymer, and the like.
 Offset handle assembly 115 includes two ends, a first end coupled to first head 105 and a second end coupled to bristle head 110. A grip 120 is provided between the first end and the second end, with an axial displacement in offset handle assembly 115 such that first head 105 is in first plane that is both parallel to, and shifted relative, to a second plane containing both bristle head 110 and grip 120. This offset provides superior ergonomics and operation to a user cleaning between the strings and the soundboard of a musical instrument, or reaching and cleaning electronic displays, or other flat surface. In the case of the strings, the offset enables the user to clean the area without extending their hand and arm to the same extent and orientation as would be required without the offset. Particularly because the uniformly flat head portion has a thickness sized to fit between the strings and the underlying soundboard. The offset allowing the head portion to remain flat under the strings as the handle is not required to be angled up to avoid having the fingers of the user's hand contact the strings during cleaning. In the case of the electronic display, the offset enables the user to easily and quickly sweep particulate matter off the electronic display with a wide contact area without risk of touching the display with the user's hand. Not all cleaning brushes 100 include an offset, or will set grip 120 to be parallel to a plane containing first head 105. Some arrangements provide first head 105 in a plane at a non-parallel angle to the plane containing bristle head 110 and grip 120.
 Not all embodiments include grip 120 having an axial displacement. In some embodiments, first head 105, bristle head 110, and grip 120 are aligned in a single plane. In some embodiments with and without the offset to grip 120, the bristles of bristle head 110 extend longitudinal-axially from grip 120 while one or more of the cleaning faces provided with the cleaning surfaces have an orientation that is orthogonal to the longitudinal axis that includes the bristles.
 There are many different possible alternate components, arrangements, and configurations falling within the scope of the present invention, some of which have been described herein. Offset handle assembly may include multiple offsets (e.g., bristle head 110 non-aligned with grip 120), or in some instances, no offset such that first head 105 is aligned with bristle head 110.
