FAQs
What’s the difference between Pressure Washing and Soft Washing?
1
Soft washing focuses on specialized detergents and cleaning solutions that do the heavy lifting to break down and remove organic material like algae, mildew, and moss. We apply these solutions with very low pressure to gently rinse away the loosened buildup without relying on force. This approach is ideal for protecting delicate surfaces while effectively eliminating the root causes of organic growth. Pressure washing uses higher water pressure to mechanically blast away dirt, stains, and embedded grime on tougher surfaces.
What types of stains and organic growth can be completely removed from surfaces, and which can only be improved in appearance?
2
Organic growth, including algae, mildew, moss, lichen, black streaks, and pollen, can typically be completely removed when we use the proper disinfectants and soaps to kill it at the root and rinse it away. Surface dirt, spider webs, and light grime are also fully eliminated. Deeper inorganic stains, such as rust, oil spots on driveways, heavy soot, or efflorescence on concrete, often penetrate porous materials. These can be significantly lightened and dramatically improved in appearance with targeted cleaning solutions and methods, but they may not always disappear entirely without additional specialized treatments.
How can I tell if my home needs to be washed?
3
In Northeast Ohio’s humid and variable climate, your house’s exterior, meaning the siding, trim, soffits, fascia, and roof, likely needs professional washing if you notice any of these signs: visible green algae, black streaks (often called tiger stripes), dark mildew spots, or moss growth, especially on shaded or north-facing sides; a dull, chalky, faded, or hazy appearance to the siding or roof shingles; heavy pollen film, tree sap residue, or spider webs clinging to surfaces; or a musty/damp odor coming from the exterior walls or eaves after rain.
Is it safe to pressure wash my vinyl or aluminum siding?
4
No, pressure washing is generally not considered safe for a vinyl or aluminum sided house when using standard high-pressure methods, especially for homeowners or inexperienced users. We at Patriot Exterior Cleaners recommend avoiding traditional pressure washing altogether for these materials and opting for soft washing instead, which uses low pressure combined with specialized cleaning solutions to gently remove dirt, algae, mildew, and organic growth without risking damage.
Is it safe to pressure wash my shingled roof?
5
No, it is not safe to pressure wash a shingled roof, especially the asphalt shingle roofs common on homes in Northeast Ohio. High-pressure water can strip away protective granules, loosen or dislodge shingles, break seals, and force water underneath, causing leaks, rot, mold, and a shorter roof lifespan, issues made worse by our freeze-thaw cycles and heavy weather. Roofing manufacturers and professionals strongly advise against it. At Patriot Exterior Cleaners, we never pressure wash roofs and instead use soft washing: specialized solutions kill algae, mildew, and black streaks at the root with very low pressure, safely removing the buildup while helping preserve the roof’s condition.
How do I prepare my home for exterior washing?
6
Preparation is minimal: Close windows and doors, move lightweight outdoor items (like chairs or planters) away from the walls if possible, and let us know about any sensitive plants or areas. We handle the rest, including protecting landscaping where needed. In Northeast Ohio, we also check the forecast to pick a dry window for best results.
What kinds of organic growth commonly appear on homes and flat surfaces in Northeast Ohio?
7
In Northeast Ohio’s humid, shaded, and lake-effect climate, the most common organic growth on house exteriors includes algae (especially the type that causes black streaks or green films), mildew (powdery gray, pink, or dark patches in damp, low-sun areas), moss (thicker green clumps on roofs and shaded surfaces), and lichen (crusty patches in green, gray, orange, or black on roofs and siding). These thrive on moisture and airborne spores, often starting as cosmetic issues but potentially trapping water and speeding up surface wear if left untreated.
What areas does Patriot Exterior Cleaners service?
8
We service Lorain, Cuyahoga, Medina, Summit, Erie, Huron, Lake, and Geauga counties.
What is oxidation on vinyl and aluminum siding?
9
Oxidation on vinyl and aluminum siding is a natural weathering process where prolonged exposure to sunlight (UV rays), oxygen, moisture, and the elements causes the outer surface or protective coating to break down. On vinyl siding, this often appears as a chalky, powdery white residue (called chalking) when you rub your finger across it, making the siding look dull, faded, or hazy, especially on sun-exposed sides. On aluminum siding, it typically shows as a similar chalky or dull layer from the painted or coated finish degrading, sometimes exposing the bare metal color underneath.
Can the oxidation or chalking be removed from my siding?
10
Yes, you can often remove or significantly reduce oxidation and chalking from vinyl or aluminum siding with the right gentle cleaning approach. For vinyl, specialized cleaners (like oxidation removers or certain soft washing solutions) applied with low pressure, soft brushing where needed, and careful rinsing can lift much of the powdery residue without damaging the material, though heavy or uneven oxidation may not come off completely and could leave some dullness. On aluminum, similar mild cleaners or controlled methods work to break down the chalky layer, but aggressive scrubbing or high pressure risks stripping the finish unevenly or exposing bare metal.
