When it comes to exterior maintenance, most homeowners know the importance of cleaning the inside of their gutters—but what about the outside? Over time, gutters develop dark streaks and stains caused by oxidation, runoff, and pollution. This discoloration, known as “tiger striping,” doesn’t come off with just water or regular pressure washing. That’s where gutter brightening comes in.

At Kelly’s Pressure Cleaning, we help homeowners across Lakeland, Bartow, Mulberry, Winter Haven, Auburndale, and Plant City bring their gutters back to life with targeted brightening solutions that clean and restore the exterior finish.

What Is Gutter Brightening?

Gutter brightening is the process of removing those black and gray streaks on the outer surface of your gutters using specialized detergents and low-pressure scrubbing techniques. These marks are usually caused by:

  • Oxidized aluminum

  • Airborne pollutants

  • Runoff from asphalt shingles

  • Tree sap and mildew buildup

Unlike basic pressure washing, gutter brightening uses a chemical treatment designed to break down the oxidation layer and lift embedded stains without damaging paint or finishes.

Why It’s Worth Doing

Many homeowners overlook gutter brightening because the gutters “still work.” But if you care about curb appeal or are preparing to sell your home, clean gutters are a detail that makes a big difference.

Benefits include:

  • A cleaner, brighter roofline

  • Uniform appearance between the gutters, trim, and siding

  • Increased home value and buyer confidence

  • Protection of gutter paint from premature deterioration

  • Better first impressions when guests or neighbors visit

Think of it like polishing chrome on a classic car—it’s not required, but it completes the look.

When to Schedule It

Gutter brightening is best done:

  • After interior gutter cleaning

  • During a full house or roof wash

  • Before putting your home on the market

  • Anytime you notice discoloration along the gutters or fascia boards

Combining gutter brightening with your regular soft washing service is the most efficient way to improve your home’s overall appearance in one visit.
