Should the pad or brush show ample wear and have reached their
replacement point, simply discard the pad or brush and replace it at the
beginning of your next shift. Brushes should be replaced when the bristle
length reaches 3/4 in (19 mm).
Alternatively, if not worn out, you can extend the life of your pad driver,
pad or brush by rinsing out any captured debris or sediment and then
hanging it to dry between shifts - a simple step that can lower your cost
to clean.
