CHOMP! Ultimate Gutter Cleaner 32 oz

CHOMP!’s 32-ounce formula is designed to quickly remove dirt, debris, and unsightly stains from gutters, siding, and exterior trim. It works on aluminum, vinyl, and steel surfaces, making it a versatile choice for mixed-material homes. The product is ready to use—no mixing required—so you can apply and wipe or rinse with a garden hose for fast results. Use caution around vegetation and plants, and test on a small area first to confirm colorfastness.
Key features include powerful cleaners that tackle runoff stains and oxidation, plus broad compatibility with common exterior surfaces. For homeowners seeking a simple, ready-to-use solution, this CHOMP! option offers straightforward application and immediate improvement in curb appeal.
CHOMP! 1 Gallon Gutter Cleaner

This larger CHOMP! formula extends the same capability to a gallon container, enabling broader coverage for bigger homes or multiple cleaning sessions. It quickly removes dirt, debris, and staining from gutters and exterior trim, including aluminum, vinyl, and steel. Like the 32-ounce version, it’s ready to use with no mixing needed, making it convenient for DIY projects and quick maintenance cycles.
F-13 Gutter Grenade

F-13 Gutter Grenade is a trusted oxidative stain remover used by professionals for over two decades. It targets the root cause of black streaks and tiger stripes by addressing the oxidation layer on painted gutters. The product supports versatile dilution, enabling strong concentration for tough stains or lighter cleaning for easier maintenance. Its dilution flexibility helps balance cost and cleaning power across different job sizes.
Gutter Guard by Southeast Softwash – Heavy Duty Cleaner

This heavy-duty cleaner is designed to lift black streaks and oxidation from gutters made of aluminum and vinyl. It’s fast-acting—simply spray, let dwell, and rinse or lightly brush for deeper cleaning on stubborn areas. The product is highly concentrated, offering cost savings when diluting with water to fit the scale of the job. It’s suitable for use with pressure washers as a touchless cleaner or for manual cleaning tasks.
Gutter Guard 4-Gallon Cleaner

A four-gallon version emphasizes scale and value for larger cleaning tasks. It promises strong black streak removal while being safe for common gutter materials. As with other heavy-duty cleaners, proper ventilation and PPE are advised, and product instructions should guide dilution ratios for different job sizes. The large container makes it practical for frequent gutter maintenance programs or seasonal cleaning campaigns.
CHOMP! Microfiber Gutter Cleaner Tool

In addition to liquid cleaners, CHOMP! offers a microfiber gutter cleaner tool to assist in physically scrubbing and wiping surfaces. The tool is designed to conform to gutter and siding shapes, enhancing contact with stubborn stains like algae, mold, mildew, and dirt. Thick caterpillar-like fibers help lift residue without excessive scrubbing, providing a hands-on option for thorough cleaning when used with compatible cleaners.
Buying Guide
Key considerations when choosing a gutter cleaner solution include surface compatibility, stain type, dilution flexibility, application method, and safety. For mixed-material homes, select products labeled safe for aluminum, vinyl, and steel. If you regularly encounter oxidation and black streaks, prioritize cleaners designed to address the oxidation layer and staining at the source. For larger properties, bulk containers or concentrates can reduce per-use costs. Always test on a small area, use appropriate PPE, and follow manufacturer dilution and usage instructions for best results. Consider having a dedicated spray bottle, brush attachment, and a microfiber tool to optimize both application efficiency and final appearance.
