The high pressure spray from your pressure washer is
capable of causing damage to surfaces such as wood,
glass, automobile paint, auto striping and trim, and delicate objects such
as fl owers and shrubs. Before spraying, check the item to be cleaned to
assure yourself that it is strong enough to resist damage from the force of
the spray.
