Thermoformed media for car wash equipment and methods of building and operating car wash equipment using such media

摘要

A car wash brush comprises an axial core structure and a plurality of foam plastic media sheets attached to the core structure in angularly spaced relationship to one another. The media sheets are preferably made of closed cell, low absorbtivity foam plastic material between about 1/8 and ½ inch thick and thermoformed into a pleated configuration with a surface pattern of raised and recessed geometric figures. The media sheets are split at least partially into individual pliant fingers.
