Must admit some door sills get pretty bad. When I come across really bad ones I tend to wipe them with a cloth for fear of getting grit in the brush.

or you could just run your hand through the brush with the water flowing a couple of times.i do this a lot every day and its the main reason i dont use flocked brushes very often(unless leaded windows)as they hold on to more dirt.
