Gutter Brightening in the Des Moines Metro
Those dark vertical streaks are oxidation bonded to the aluminum. Brightening removes them. Cleaning the inside of the gutter does not.
What Those Black Streaks Actually Are
The dark vertical stripes running down the outside face of your gutters are not dirt, which is why washing them does nothing. They are oxidation, bonded to the aluminum, mixed with the road film and pollen that sticks to it.
People call them tiger stripes. They show up on gutters long before the gutter is anywhere near the end of its life, and they make a well-kept house look neglected from the curb.
Why Cleaning the Gutters Does Not Fix This
Gutter cleaning is about the inside of the channel. Brightening is about the outside face. They are different problems and one does not touch the other, which surprises most people who have just paid for a cleaning and noticed the outside still looks bad.
Brightening uses a treatment that breaks the oxidation bond, then gets agitated and rinsed. It is the only thing that removes the stripes short of replacing the gutter.
When Brightening Is Worth It
Two situations mostly. You are selling the house and the gutters are the first thing anyone sees from the street. Or the gutters are otherwise fine and you are not ready to replace something that still works just because it looks tired.
It pairs naturally with a cleaning. The ladder is already up.
Why a Gutter Company Does This Better Than a Pressure Washer
Brightening usually gets sold by pressure washing companies as an add-on to a house wash. The instinct that comes with that trade is pressure, and pressure is the wrong tool here. Oxidation is a chemical bond, not dirt, and the aluminum behind it dents and streaks if you attack it.
We come at it from the gutter side instead. Brightening is one of three things we do, all of them gutters, so the person treating your gutter face has spent the season looking at gutter faces and knows the difference between oxidation, road film, and a finish that is simply spent.
Sometimes the honest answer is that brightening will not get you where you want, and the gutter is just old. You will hear that from us, because we do not sell the replacement either.

What are tiger stripes on gutters?
The dark vertical streaks on the outside face of aluminum gutters. They are oxidation bonded to the metal, not dirt, which is why pressure washing and regular cleaning do not remove them.
Is gutter brightening the same as gutter cleaning?
No. Cleaning clears the inside channel so water flows. Brightening treats the outside face so the gutters do not look streaked. Most people want both, but they are separate jobs.
Will brightening damage my gutters?
Done correctly, no. The treatment is matched to the finish and rinsed thoroughly. The risk with this service is someone using something too aggressive and etching the aluminum, which is permanent. Ask what they are putting on your house.
