It can Do if you don’t know how to protect them
Soft washing uses professional-grade sodium hypochlorite (bleach) to kill (Gloeocapsa Magma), which is a type of algae that leaves ugle black streaks on roofs , walls and other surfaces, causing damage in the process. Bleach also works to kill and remove other organic matter such as mildew, moss, and lichen from homes and buildings.
The problem is that while bleach is great at killing the organic matter from roofs and walls, it can also kill the plants, trees, shrubs, flowers, and grass around homes and buildings.
While there are no guarantees you won’t kill or damage plants, there are things you can do to greatly minimize the risk.
✅ 1. Channel the down pipe with large plastic tubing to other part of the building. If you are roof cleaning and the home or building’s gutters are working properly, your soft wash solution is going to run to the gutters and out the down pipe.
✅ 2. Water, water, water and some more. Keeping the plants saturated with fresh water will keep them hydrated, meaning they cannot soak up as much of the soft washing solution. Ideally, you will have two people on the job site when soft washing, one who does the cleaning, and one who keeps the plants watered.
Generously pre-wet all the plants around the house before cleaning, paying special attention to those that are directly below the roof line. You can use a garden hose for this.
✳️ We use a product called plant wash afterwards. Plant Wash when used during the Soft Washing application will ensure you don’t damage plants and grass.✳️
