Fill material decides what the brush may touch. Steel cuts hardest and marks anything softer than itself. Brassed steel is gentler. Solid brass is softer again and will not spark, which is why it is used near fuel. Stainless resists corrosion and does not contaminate the surface. Reading the fill before the size is what stops a brush marking what it was bought to clean.
Nylon fill sits at the softest end and cleans without abrading at all, which suits a finished surface or one that would corrode if steel particles were left embedded in it. Brass also leaves no ferrous particles behind, which matters where the surface will be painted afterwards.
Form follows access. A hand brush at 250 to 260mm covers an open surface. A brush with a scraper on the end deals with the deposit a brush alone will not lift. Miniature sets reach into a recess where a full brush will not enter. Sets are also the cheaper route into several fills where one brush would be wrong for half the work.
Sets cover several fills at once: two, three, five and eight piece sets are held, along with a rotary tool brush set at 18 pieces for powered cleaning. The roofing tools on this leaf are a separate group: tar brushes on short and long handles, a lead dressing tool, a lead knife, a roofing hammer at 600g and a roofer's square.
