An absolute staple and the soft cousin of the stiff short brush.  These two brushes are identical but with different bristles, this one is the soft version. 

This is the brush you need to best scrub the face of mag wheels, cleaning engine bays and more delicate surfaces where you need a brush but you want the brush to be soft.  Chemically resistant and durable bristles and handle, a must have to make light work of rougher jobs.   Can also be used to clean rubber and plastic, but we recommend also having our stiff version of this brush here as well which will clean dirty tyres faster.
