FAQs Will Safewash Powerwash cleaning harm my plants? All of our cleaning work is absolutely safe for plants, pets and people. Our exclusive eco-friendly, biodegradable soap solution cleaning method uses warm water at low pressure, along with ultra-safe self-neutralizing cleaning and rinsing agents. Will your cleaning damage the paint on trim or siding? Because of our low-pressure cleaning and safety approved cleaning products, damage is not possible. Will pressurized water be forced behind my siding? Unlike high-pressure washing, Safewash uses a specific volume of water over pressure of water, making sure your siding is safe and secure.
