Make sure to completely remove all material from the inside
of the piston chamber by scrubbing with the brush. Even a
small amount of material can dry like glue and keep the
piston from moving, causing damage to the sprayer.
Make sure to keep the vent hole on the pump housing clean
and unblocked or a vacuum can build up in the container
and cause damage to the sprayer. A toothpick or
straightened paper clip can be used to clean it.
