Wire Saucer Cup Brushes’ saucer-shape is ideal for cleaning corners, recesses, and other hard-to-reach areas. Choose twist knot style for heavy-duty cleaning jobs, or crimped style for light- to medium-duty cleaning. Powder-coated and color-coded hubs won't rust, preventing cross-contamination for the end-user. Choose red hubs for steel applications or blue hubs for stainless steel use.
