What's Actually in Our Cleaning Solutions (and Why It's Biodegradable)

It is a fair and sensible question: what exactly are you spraying on my house, my roof and my garden? Homeowners deserve a straight answer, not a brush-off. Here is a plain explanation of what goes into exterior cleaning solutions, why biodegradable products matter, and how the way they are used keeps your property safe.

What the solutions are for

Exterior cleaning solutions are designed to do one main thing: kill and break down the living growth, moss, algae, mildew and lichen, that fouls surfaces in our climate, along with lifting general grime. The point is that the chemistry does the cleaning so the physical pressure can stay low, which is what protects roofs, siding and other surfaces from damage.

A solution is matched and diluted to the surface and the job. Roof and siding soft-wash mixes, wood-safe deck cleaners, degreasers for concrete and specialty removers for rust or efflorescence each suit their task, rather than one harsh product for everything.

Why biodegradable matters

Biodegradable means the product breaks down into harmless components over time rather than persisting in the soil and water. That matters because exterior cleaning happens right next to your gardens, lawns and the storm drains that lead to local waterways. Using biodegradable solutions at controlled dilutions is a big part of doing the job responsibly.

It is a real difference from the crude approach of throwing straight bleach or strong acid at a surface, which is what people picture and rightly worry about. Responsible exterior cleaning is deliberately not that.

How they are used safely

The products are only half the picture, technique is the other half. Landscaping is pre-wetted with plain water so it absorbs far less of anything that drips, sensitive plants are covered where needed, everything is rinsed afterward, and overspray and wind are watched. Applied this way, an area is safe to use normally once it has been rinsed.

If you have particular concerns, a pond, a vegetable garden, specific plants, or anyone with sensitivities, say so before the work starts so the approach can be planned around them. A company that cannot explain what it uses and how it protects your property is one to be wary of.

Common questions

What is in exterior cleaning solutions?

Diluted, surface-matched cleaning mixes designed to kill and break down moss, algae, mildew and lichen and lift grime, so that physical pressure can stay low. Different tasks use different mixes rather than one harsh product for everything.

Are the products safe for my garden and the environment?

Responsible exterior cleaning uses biodegradable products at controlled dilutions, applied with plant pre-wetting, covering and rinsing. That breaks down harmlessly over time, unlike throwing straight bleach or acid at a surface.

What if I have specific plant or health concerns?

Tell the company before work starts, ponds, vegetable gardens, particular plants or sensitivities, so the approach can be planned around them. A company that cannot explain what it uses and how it protects your property is one to be wary of.
