Gutter Brightening
Gutter brightening is cleaning the outside face of gutters to remove black streaks, chalky oxidation, and dirt that a normal gutter cleaning leaves behind. It restores the original color of painted aluminum gutters with an oxidation-removing cleaner followed by a thorough rinse.

In depth
The dark streaks, known as tiger striping, form as dirt and airborne grime wash down the gutter face with every rain. Brightening is an exterior-only service, separate from clearing debris inside the trough. Results depend on the finish: a gutter whose paint has failed will not brighten, because the coating itself is gone. Pros protect nearby paint, siding, and plants from the cleaner and rinse everything afterward. It is commonly done together with a house wash so the gutters match the clean siding.

Tiger Striping
Tiger striping is the pattern of dark vertical streaks that appear on the exterior face of aluminum and painted gutters, running from the gutter lip down toward the ground. The stripes are caused by electrostatic attraction between negatively charged dirt particles (pollen, dust, algae spores, atmospheric fallout) and the positively charged painted or anodized aluminum surface. Over years, these particles bond into a film that ordinary rinsing and even pressure washing will not remove without chemistry.
Oxidation
Oxidation is the chalky, faded film that forms when a surface reacts with oxygen, UV light, and moisture over time. On vinyl siding it feels like white powder that rubs off on your hand; on aluminum siding and gutters it shows as dull, chalky patches or streaks.
Gutter Flushing
Gutter flushing is running water through gutters and downspouts after the debris is removed to confirm that everything drains. It washes out fine silt and shingle grit and reveals leaks, low spots, and clogged downspouts that dry cleaning would miss. It is the test that proves a gutter cleaning actually worked.
Acid Wash
An acid wash in exterior cleaning is the application of a dilute acidic solution — most commonly muriatic (hydrochloric), phosphoric, oxalic, or a proprietary masonry blend — to dissolve mineral-based staining that bleach and surfactants cannot touch. Typical targets include efflorescence on brick, heavy rust from fertilizer or irrigation, mortar haze on new brickwork, mineral deposits on glass, and battery acid on concrete. Acid wash is not a general cleaning method — it is a targeted chemistry tool for specific stains on specific substrates.
Fascia Board
The fascia board is the horizontal board running along the lower edge of the roof, to which gutters are typically fastened. It covers the ends of the roof rafters and gives the roofline a finished appearance. In wood construction, fascia is typically 1x6 or 1x8 pressure-treated or painted pine; in newer construction, it is often PVC or fiber cement. Because it is exposed to constant moisture from gutters, drip, and snow melt, the fascia is one of the most rot-prone boards on a home.
