How to Remove Black Streaks from your Gutters

Do you have gutters on your house with dark black streaks? They should be easy enough to remove.


You can go to your local Dollar Store and buy generic oven cleaner, hair net/cap, and paint mask, and goggles

Be Careful and use ladder to go up to the gutter. Spray with oven cleaner and move to next section. Do not over reach while on a ladder as you could fall.

Do one side of your house at a time. After spraying with oven cleaner let sit for about 10 to 15 minutes and then rinse with garden hose. Be sure to rinse entire wall at the same time

Finish by doing the remaining sides of your house.
