Why Clean Gutters Still Look Dirty: The Truth About Tiger Striping

You cleaned your gutters.
 Or you paid someone to do it.

Either way, you step back expecting that “finished” look…
and something’s off.

They’re working fine.
 But they don’t look clean.

That’s not your imagination.


What’s Really Going On

There are two completely different jobs when it comes to gutters:

1. Cleaning the inside (function)
 2. Cleaning the outside (appearance)

Most services stop at the first.

But the second?
 That’s what everyone actually sees from the street, the driveway, and the curb.


What Is Tiger Striping?

Those vertical black streaks on the face of your gutters are called tiger stripes.

They’re caused by:

  • Roof runoff carrying asphalt and shingle residue
  • Airborne pollutants sticking to moisture
  • Water repeatedly flowing over the same edges

Once they show up, they don’t just rinse away.

They build up, and bond.

Why They Don’t Come Off Easily

These aren’t surface stains.

They attach to the finish of the gutter, especially aluminum, and removing them takes:

  • The right chemistry
  • The right method
  • The right level of control

Too aggressive? You risk damaging the finish.
 Too light? You get nowhere.


The Gap Most People Don’t Realize

A standard “gutter cleaning” doesn’t include removing tiger striping.

So homeowners end up asking:

“Why do my gutters still look dirty?”

Because the visible part was never actually cleaned.


What Most Products Get Wrong


If you’ve gone looking for a solution, you’ve probably seen products like:

  • Gutter Butter
  • Gutter Grenade
  • Chomp Gutter Cleaner
  • And other heavy-duty chemical cleaners

They all promise results, but come with trade-offs:

  • Mixing chemicals
  • Pre-washing surfaces
  • Hoses and runoff management
  • Scrubbing… a lot of scrubbing
  • Risk to plants, siding, and finishes

They can work, but they’re often overkill for the job.

And they turn a simple task into a full production.


Where TigerStrike / TigerStrike Changes Everything



This is where Tiger Strike, also known as Tiger Strike, takes a completely different approach.

No mixing.
 No pre-wash.
 No power washers.
 No hoses.
 No aggressive scrubbing.

Just a controlled, direct solution designed specifically for gutter faces.

What makes it different:

  • Less mess - no runoff, no overspray
  • More control - you clean exactly where needed
  • Faster results - wipe and see the difference immediately
  • Safer process - no harsh chemical handling or setup

It’s not about overpowering the problem.

It’s about solving it cleanly.


The Difference When It’s Done Right



When the face of the gutter is actually cleaned:

  • Gutters look new again
  • The entire house sharpens up visually
  • The job finally feels complete

That’s the moment most people expected in the first place.


Bottom Line

Clean gutters don’t always look clean.

But when you remove tiger striping, 
 that’s when everything comes together.

And once you see the difference,
 you won’t settle for half-clean again.
