for cleaning purposes, as they are strongly abrasive; common examples include the toothbrush and toilet brush. The bristle brush and the scrub brush are common household cleaning tools, often used to remove dirt or grease from pots and pans. Bristles are also used on brushes other than for cleaning, notably paintbrushes. Bristles are distinguished as '' flagged'' (split, bushy ends) or ''unflagged;'' these are also known as ''

'' or ''unflocked'' bristles. In cleaning applications, flagged bristles are suited for dry cleaning (due to picking up dust better than unflagged), and unflagged suited for wet cleaning (due to flagged ends becoming dirty and matted when wet). In painting, flagged bristles yield more even application.''Old-House Journal,'' May 1986

Natural types

Bristles are found on pig breeds, instead of fur. Because the density is less than with fur, pigs are vulnerable to sunburn. One breed, the
