Bleach can be highly dangerous if inhaled, and it can kill plants, flowers, and neighbors' animals that accidentally ingest it. 

We don’t recommend pressuring washing clapboard siding. At high levels of pressure, a pressure washer can damage wood siding permanently. Pressure washing can also make it easier to drive water into the cracks of clapboard (which are recommended for easier drainage), causing moisture damage.
