## Description

Product Description BioAdvanced 2-in-1 Moss and Algae Killer and Cleaner uses one formula to effectively address moss & algae control, wherever it grows. This moss killer for roofs and moss killer for lawns features a 2-in-1 formula that acts as both a moss and mold* killer spray without staining or harming lawns. Within hours, moss quickly turns yellow, then brown, making it easy to wash away by hand or rain. A single application lasts up to one year. Utilizing its high coverage and durability, it is ideal for continuous lawn maintenance & outdoor cleaning on lawns, patios, roofs, buildings, decks, and driveways. Easily attach the ready-to-spray applicator to your garden hose to activate the sprayer with your thumb. BioAdvanced 2-in-1 measures 32 ounces and treats up to 500 square feet, working as a moss roof solution and patio cleaner for concrete. One formula kills moss and algae on patios, lawns, and roof shingles. While other brands may require two separate formulas, BioAdvanced covers it all. Ideal applications include growth prevention on lawns, patios, fences, mulch, gravel, roofs, and buildings, with effective use anytime of the year. Active Ingredients: Potassium soap of fatty acids: 22.11%. EPA Registration Number: 67702-12-92564. (*not including species considered public health concerns) From the Manufacturer One formula kills Moss and Algae wherever it grows. Treats lawns, patios PLUS roofs and buildings. With other brands you'd need two formulas to treat all areas. Kills: Moss, Algae, Lichen. Where to Use: Lawns, decks, patios, fences, mulch, driveways, gravel, roofs and buildings. When to Use: Anytime during the year. Active Ingredients: Potassium soap of fatty acids: 22.11%.

Review: Highly Effective Moss and Algae Control - Fast Results - I purchased the BioAdvanced 2-in-1 Moss and Algae Killer for Lawns, and I couldn't be more impressed. The formulation is exceptional—professionally developed, concentrated, and clearly designed with effective active ingredients. Application was quick and straightforward, and the product performed flawlessly right from the first treatment. The spray provides smooth, even coverage and delivers consistent, visible results within days. I noticed the moss beginning to darken and die back within 24-48 hours, with complete elimination after one week. The 2-in-1 formula not only kills existing moss and algae but also helps prevent regrowth, keeping my lawn looking clean and healthy. The coverage area is generous, and the hose-end sprayer attachment makes application effortless across large lawn areas. The overall effectiveness and performance exceeded my expectations, especially for the price point. My lawn has transformed from patchy and moss-covered to lush and green. I'd highly recommend this moss and algae killer to anyone looking to restore their lawn's health and appearance without damaging the grass.
Review: Kills moss, but bottle defective. - This stuff definitely works at killing moss. Within a few days all the moss on my walkways was dead and brown. The problem is, it doesn’t go anywhere, so then you have to pick/scrape it all out. Also, the most recent bottle I received, the mixing bottle didn’t work. I had to dump it into another sprayer I have in order to use it.
