Abstract: Flash vortex brush cleaning apparatus is provided which comprises a device and method for cleaning inner channels of boreholes which have been drilled or cored within solid substrates, particularly, concrete, masonry, grout, where the boreholes are to be used to bond adhesive anchors therein. Flash vortex brush device comprises a straight tubular shaft; a coil cleaning brush. Tubular shaft includes a first end including an open inlet; opposing second end including an open outlet; first end including a connector element. Coil cleaning brush includes bristles secured in channel affixed wound proximate to second end of shaft developed of pitch to form an open wound coil. Connector element provides removable attaching means to a variety of pre-existing nozzles. For rapid efficient cleaning, first embodiment for use includes flash vortex brush removably attached with air nozzle; second embodiment for use includes flash vortex brush removably attached with water nozzle.
