a. Don’t scrub to hard with the brushes as the bristles will permanently bend over.
b. The best time to clean the bristles is while the gunge is still wet. Simply spray “Flusher” into the bristles & with a sharp tap, smack the bristle onto a hard surface, the gunge should fall out.
c. If any gunge dries in the bristles, comb the bristles through a wire brush.
