How to get gutters clean?

I sprayed Tilex on my gutters with good results. (Wear old clothing and eye protection.)

use Wet and Forget. It will come off little by little without all the work.

I feel your pain. I've used the pressure washer too and bleach with no luck. The bleach lightened it a bit but it's still there. They look so awful this way. I wonder if the only alternative is painting them?

I've had this one siding as well. Its as if the stains just penetrates so deep into the gutters that its nearly impossible to remove. The only thing I can think to try is a magic eraser. I assume you used bleach as one of your OTC attempts. I'll be curious to see if someone else has any ideas. I found I just had to get the stains as light as I could, but nothing got rid of it completely. There weren't magic erasers around when I had the problem, so don't know if that would have worked or not. But after all, they are 'magic', lol!!

Hello Nancy

I have found that cooktop cleaner and a magic sponge eraser works on my white vinyl rail- grayish film and stains. It might work on a gutter too. If you have some on hand it might be worth a try.
