In cases where inner rims are thick with baked on brake dust, normal wheel brushes are sometimes too flexible and soft to dislodge it, even with strong chemical assistance. This is where the EZ Detail Go EZ Brush comes in handy. Unlike the other wheel cleaning brushes in the EZ Detail line up, which are flexible and soft, the Go EZ Brush is stiffer and has a stronger scrubbing action, and is designed to withstand the rigours of professional use. Like its siblings, it does tend to throw off a fair amount of splatter, but as long as you stand over the wheel rather than squatting in front of it this can be largely avoided. If you need a heavy duty wheel brush then this is the one for you.
