mrmichaeljmoore 14 Report post Posted August 1, 2011 Homewoner here with a question about preventing the black streaks on gutters (apparently called "Tiger Stripes").... I celaned my house and gutters this weekend. Everything looks nice and clean and new, including the gutters. I did a quick google search this morning and found two products designed to prevent the Tiger Stripes. Has anyone seen either of these two porducts? https://gutteredge.com/index.php Snaps into place, no screws needed. StainGuarderĀ®TM - "Because stripes belong on tigers...not on gutters." Requires a screw through the top lip of the gutter Anyone have any experience with these? Or have a better idea to prevent the stripes? thanks. mm Share this post Link to post Share on other sites
