Bleach is commonly used to power wash houses and roofs because it quickly kills mold, mildew, algae and moss. However, if you’re not careful it can also kill the plants and trees around your house. Take these simple steps to ensure your landscaping stays alive and well when pressure washing your house:
- Pre-soak all plants. We can’t stress this enough. This is the key step to ensuring your plants stay protected from bleach and other harsh chemicals. Use a garden hose or a pressure washer that is adjusted to a low pressure rating.
- Use tarps to cover bushes and shrubs. Just be careful on hot and sunny days; the plastic can create a greenhouse effect and will heat the plants up too much which can ultimately kill them.
- Add surfactant to your bleach. Surfactants help bleach cling to the surface of your house and roof which helps prevent run-off, and also helps reduce the amount of bleach needed to clean. They are also often eco-friendly.
- Apply soap from the bottom, up. This will help create a barrier to chemical run-off.
- Rinse thoroughly. After you are done rinsing the bleach off of your house and roof, rinse your plants and shrubs again to wash off any chemicals that may have dripped on them during the chemical application.
