I noticed a while ago that Sneeboer use brass bristled brushes (thats a hood tongue twister!) but always struggled to find any. Well, good old tinker and fix to the rescue! The point of brass over steel is that it's much softer, almost like a toothbrush but still abrasive enough to get through dried on dirt and muck. At the prices they are, I've got 6 (3 of each size) and put in shed, tool box and allotment so there's always one to hand. If you want to be really posh, drill a hole at the top and add some string and hang it up! Another brilliant product you didn't know you needed until you used it!
