The brushes from Auto Finesse, first impressions, nicely made wooden handle, long very soft boar hair, longer than I expected infact, but once you use it the long hair gets into the tightest of areas in the wheels. So to compare with the ever popular 1 inch round brush so you can see them next to each other. One dirty wheel that needs a good clean this has not been washed for a month. Iron out was used and left for a couple of minutes (nice bleed out) the long hair getting in the tight area around the valve Also really helped foam up the iron out and work its magic! After a rinse with a open hose
