and shapes depending on the stiffness required. Brush bristles are small- or large-gauged wires made of
steel, brass, or stainless steel. Use steel wire bristles on steel, wood, and masonry; brass wire bristles on
brass; and stainless-steel wire bristles on stainless steel. To prevent damage, store wire brushes by
hanging them on a wall.

b. Painter's Dusters. Painter's dusters are used to remove fine dust before painting. Dusters are
usually flat or oval in shape and are fitted with handles similar to those on paintbrushes. Store painter's
dusters by hanging them on a wall or by wrapping paper around them and laying them flat. Never stand
dusters on their bristles.
c. Scrapers. Paint scrapers are grouped as pull, push, or molding (Figure 3-2). Scrapers will
vary based on their intended uses; for example, one scraper type is used to remove deteriorated paint
from the surface, and another is used to remove plane and mill marks from wood surfaces (Figure 3-3).
Scrapers made of flexible steel must be kept sharp to do good work. Figure 3-4, page 3-4, demonstrates
how hand-scraper edges are sharpened. The cutting edges of a cabinet scraper (Figure 3-5, page 3-5)
and a scraper plane (Figure 3-6, page 3-5) are sharpened similarly to the hand scraper. You should
never toss scrapers into a toolbox with other tools as this will nick the sharp edges and make it necessary
to resharpen them.
